7.3 Configuring the Ethernet Port on the IPM Card

In the backplane, the IPM card provides four FE ports to cascade the slave frame. In

the front panel, the IPM card provides one FE optical port, two FE electrical/optical

ports, and one or two GE optical ports to connect the upstream equipment.

Ethernet ports on the IPM card are numbered as follows.

0–1: The two ports on the Ethernet subcard. The upper port is numbered as 0, and

the lower port as 1. If the subcard offers only one FE or GE port, the port number is

0.

2–5: The four FE ports used for subtending the slave frame.

6–7: Two internal FE ports used to connect the PVM card. The port attributes must

be consistent with those of the ports of the PVM card. These two FE ports are

configured together. Use the default value in general.

7.3.1 Command List

7.3.2 Entering the IPM mode

To enter the IPM mode, use the interface ipm command. In this mode, you can

configure and manage the Ethernet ports on the IPM card.

7.3.3 Enabling/Disabling an Ethernet Port

To enable or disable an Ethernet port, use the [undo] shutdown command.

You can use an enabled Ethernet port. By default, the port is enabled.

7.3.4 Configuring the Attributes of a Port

Table 7–3 shows the Ethernet port attributes.

Table 7–3 Ethernet port attributes

GE optical port N Y N N N Y N N N N

“Y” means that the attribute is supported by the port, and “N” means that the attribute is not supported by the

port.

Follow the steps below to configure an Ethernet port.

I. Setting the duplex mode of an Ethernet port

To set the duplex mode of an Ethernet port, use the duplex command.


8/84



7-5

There are two types of duplex states: half duplex and full duplex.

In the half duplex mode, a port is allowed to transmit or receive data in only one

direction.

In the full duplex mode, a port is allowed to transmit and receive datasimultaneously.

When you configure the duplex mode, keep two connected ports consistent, and avoid

half duplex at one end but full duplex at the other.

Do not configure the duplex mode for an aggregation port.

II. Setting the line type of an Ethernet port

To set the line type of an Ethernet port, use the mdi command. The line types of

interconnected ports must be set consistently.

This setting is applicable to FE electrical ports, and not to FE/GE optical ports.

The network cable type of an FE electrical port can be either straight through or

cross-over cable. By default, the MDI type of the FE electrical port is auto (auto

sensing).

III. Setting the bit rate of an Ethernet port

Use the speed command to set the bit rate of an Ethernet port. The bit rate of two

interconnected ports must be consistent.

An FE electrical port supports both 10 Mbit/s and 100 Mbit/s. Its default setting is auto

(auto negotiation), and 100 Mbit/s is recommended.

An FE optical port supports only 100 Mbit/s, and a GE optical port supports only 1000

Mbit/s.

IV. Enabling/Disabling the flow control of an Ethernet port

Use the flow-control command to enable the flow control. Use the undo flow-control

command to disable it. By default, the flow control of an Ethernet port is disabled.

If congestion occurs, the system performs flow control only when it is enabled.

7.3.5 Configuring the Default VLAN of a Port

For the system to be compatible with terminals that do not support VLAN, configure a

default VLAN for the Ethernet ports on the IPM card. To configure a default VLAN for an

Ethernet port, use the native-vlan command.

When a port receives packets:

If the packets do not contain any VLAN tag, assign the default VLAN tags to them.

If the packets already contain VLAN tags, do not add the information.

When a port transmits packets:


9/84



7-6

If the default VLAN of the port is the same as the VLAN included in the transmitted

packets, the system removes the VLAN tag from these packets.

If not, the port keeps the VLAN tag with these packets for transparent VLAN

transmission.By default, the ID of the default VLAN (PVID) is 1. To modify the default VLAN of a port,

do as follows:

1) Create a standard VLAN, and then assign the port to the VLAN.

2) Define the created VLAN as the default VLAN.

Note:

A port can be configured with only one default VLAN.

Different ports can have the same default VLAN.

Example

To set the default VLAN of port 1 as 5, do as follows.

huawei(config-if-ipm-0/3)#native-vlan

{ portid|all }:1

{ vlan }:vlan

{ vlanid }:5

7.3.6 Configuring the Traffic Suppression

You can limit the throughput of broadcast packets, multicast packets and unknown

unicast packets passing through a port by discarding the packets that exceed the set

limit. This prevents the system from malicious attacks from unknown users and avoids

network congestion.

The UA5000 provides 12 traffic suppression levels.

To query the 12 traffic suppression levels, use the display traffic-suppress command.

Example

To query the traffic suppression level of port 0/3/2 on the IPM card, do as follows:

huawei(config-if-ipm-0/3)#display traffic-suppress

{ portid|all }:2

Traffic suppression ID definition:

Current traffic suppression ID of broadcast : 7

Current traffic suppression ID of multicast :--

Current traffic suppression ID of unicast : 7

Note:

The default traffic suppression level for broadcast and unknown unicast packets is

7.

The IGMP proxy is enabled by default. In this case, do not configure traffic

suppression levels for the multicast packets. Hence, disable the IGMP proxy before

configuring a traffic suppression level.

I. Setting a traffic suppression level

To set the traffic suppression level for a packet type, use the traffic-suppress

command.

Example

To set the traffic suppression level for broadcast packets on port 0/3/2 on the IPM card

as 6, do as follows:

huawei(config-if-ipm-0/3)#traffic-suppress

{ portid|all }:2

{ broadcast|multicast|unicast }:broadcast

{ value }:value

{ value }:6

Query the configuration result using the display traffic-suppress command.

II. Cancelling the traffic suppression

To cancel the traffic suppression of a specified packet type, use the undo

traffic-suppress command.

Example

huawei(config-if-ipm-0/3)#undo traffic-suppress

{ portid|all }:2

{ broadcast|multicast|unicast }:broadcast

To query the configuration result, use the display traffic-suppress command.

huawei(config-if-ipm-0/3)#display traffic-suppress

7.3.7 Aggregating Ethernet Ports

To aggregate Ethernet ports, use the link-aggregation command. To delete the

aggregated Ethernet port, use the undo link-aggregation command.

Port aggregation is intended to bundle multiple ports together so that the incoming and

outgoing load can be distributed among member ports. Meanwhile, to increase thesecurity of a link, ports within an aggregation group can serve as a backup for each

other.

Up to four aggregation groups can be configured for one IPM card, with each group

containing up to eight ports.

Note:

The operations on the master port take effect on all ports in the aggregation group.

Two aggregation modes are available: ingress and ingress-egress. The ingress mode

means that packets are distributed among member ports according to the source MAC

address. The ingress-egress mode means that packets are distributed among member

ports according to both the source and destination MAC addresses.

To aggregate multiple physical ports, make sure that the following preconditions are

met.

All physical ports are located in the same slot.

All these ports work in the full duplex mode.

The network cable of these ports cannot be in the auto negotiation mode.

These ports work at the same bit rate and the bit rate cannot be in the auto

negotiation mode.

These ports have the same default VLAN (PVID) and VLAN attributes.

A port belongs to only one aggregation group.

None of these ports is a member of an aggregation group

None of these ports is a mirror destination port.

Example

To configure an ingress aggregation group consisting of ports 0 and 1, do as follows.


13/84



7-10

1) Configure the port aggregation parameters.

The ports to be aggregated must work at the same bit rate and in full duplex mode.

huawei(config-if-ipm-0/3)# mdi 0 normal

huawei(config-if-ipm-0/3)# mdi 1 normal

huawei(config-if-ipm-0/3)#duplex 0 full

huawei(config-if-ipm-0/3)#duplex 1 full

huawei(config-if-ipm-0/3)#speed 0 100

huawei(config-if-ipm-0/3)#speed 1 100

2) Configure the port aggregation.

huawei(config-if-ipm-0/2)#link-aggregation

{ port-list }:0,1

{ mode }:ingress

3) Query the port aggregation information.Use the display link-aggregation command to view the information about an

aggregation group, including master port, member ports and aggregation mode.

huawei(config-if-ipm-0/2)#display link-aggregation

-----------------------------------------------

Master port Sub-ports Mode

-----------------------------------------------

0 1 ingress

-----------------------------------------------

Total: 1 link-aggregation set(s)

7.3.8 Configuring Ethernet Port Mirroring

The IPM card has the port-based mirroring function. It can duplicate the packets

passing one or multiple ports (source port) to the monitor port (destination port) for

analysis and monitoring. With the port mirroring function, you can monitor all source

ports by analysing the packets of the destination port, greatly facilitating the fault

location.

To configure port mirroring, use the mirror port command. To eliminate port mirroring,

use the undo mirror port command.

Note:

Do not define an aggregated port as the mirror destination port. You can define it as

the mirror source port.

The switchover of the control card clears all port mirroring settings.


14/84



7-11

Example

1) Establish a port mirroring which mirrors source ports 2 and 3 to destination port 4

in the transmitting direction:

huawei(config-if-ipm-0/3)# mirror port { src-port-list }:2,3

{ dst-portid }:4

{ mirror-direction }:ingress

Add port 2,3 ingress direction as mirror source port successfully

2) After the port mirroring is established, use the display mirror command to query

the port mirroring.

huawei(config-if-ipm-0/3)#display mirror

------------------------------------------------

Source port Direction Destination port

------------------------------------------------

2 ingress 4

3 ingress 4

------------------------------------------------------------------------

3) If the port mirroring is established, use the mirror port command to add new

source ports to it.

huawei(config-if-ipm-0/2)# mirror port 0x2 3 egress

Add port 1 egress direction as mirror source port successfully

7.3.9 Querying Port Information

The related commands are as follows.

To query the configurations of an Ethernet port, use the display board

frameid /slotid command.

To query the state of an Ethernet port, use the display port state command.

To query the current traffic of an Ethernet port, use the display port traffic

command.

To query the statistics of an Ethernet port, use the display port statistics

command.

command. Port resources include the maximum number of VP and VC connections,

and so on.

Example

To query the VP/VC resources of ATM port 0/7/0, do as follows:

huawei(config-if-aiu-0/7.optic)#display resource 0

The total VPIs supported by the port is 256

The number of available VPIs of VC connection supported by the port is 8

Max VP connection support on this port is 248

Max VC connection support on this port is 7936

Available VPI scope is {0,255}

Available VCI scope is {32,1023}

The port is configured as UNI

Port speed 155Mbps

Port of 155M does not support SD alarm

7.4.6 Setting the maximum VPI Number for a VC Connection

To set the maximum VPI number for a VC connection, use the vpi-num-for-vcc

command. The vpi number must be 2n, such as 1, 2, 4, 8…128.

7.4.7 Setting the Port Mode

To set the working mode of an ATM port, use the port mode command. To query the

working mode, use the display board command.

The 155 Mbit/s port can work in the OC-3c/STS-3c or STM-1 mode. By default, the port

works in the STM-1 mode.

7.4.8 Querying the Port Statistics

To query the statistics of an ATM port, use the display statistic command. The

statistical information includes receiving/transmitting cells and bit error events of the

ATM port.

7.4.9 Clearing the Port Statistics

To clear all the statistics of an ATM port, use the clear statistic command.

7.4.10 Inserting an Alarm Event

To insert an alarm event into an ATM port, use the event-insert command.

You can insert the following alarm event into the ATM port:


18/84



7-15

Line alarm indication signal (LAIS)

Loss of frame (LOF)

Loss of signal (LOS)

Line remote defect indication (LRDI) Path alarm indication signal (PAIS)

Example

To insert the LOS alarm event into ATM port 0, do as follows.

huawei(config-if-aiu-0/7.optic)#event-insert 0 los

huawei(config-if-aiu-0/7.optic)#display event-insert 0

Inserted LOS event

To stop inserting alarm events into an ATM port, use the undo event-insert command.

To query the inserted alarm event, use the display event-insert command.

7.4.11 Inserting a BIP Bit Error Event

To insert a BIP bit error event, use the bip-insert command.

You can insert the following BIP bit error events into the ATM port:

Line BIP bit error (LBIP)

Path BIP error event (PBIP)

Section BIP bit error event (SBIP)

7.4.12 Setting the Loopback of an ATM Port

To set the loopback test, use the loopback command.

The ATM port supports local loopback and remote loopback.

In the local loopback, the system duplicates cells transmitted from the AIU card to

the port. The duplicated cells will be sent back to the AIU card.

In the remote loopback, the system duplicates the cells sent to the backplane. The

duplicated cells will be sent back to the ATM port.

Figure 7–1 shows the loopback.

To disable the loopback after the loopback test is completed, use the undo loopback

command.

7.4.13 Configuring the ALS Switch of an Optical Port

When a communication link fails, the Automatic Laser Shutdown (ALS) function can

shut down the optical sources automatically at both ends of the link. After that, the

devices on both sides send optical signals regularly to detect the link state until the link

resumes. After the link resumes, the optical ports on both sides work normally.

I. Enabling/Disabling the ALS function

To enable or disable the ALS function, use the als enable/disable command. By

default, the function is disabled. When the ALS function is disable, the optical port on

the device does not shut down even when the link fails.

Example

Assume that:

The delay time of sending the optical detection signal is 100s (delaytime).

The port sends the optical detection signal at the interval of 50s (txontime).

To enable the ALS function, do as follows:

huawei(config-if-aiu-0/7.optic)#als enable

{ portid }:0

{ |delaytime }:100

{ txontime }:50


20/84



7-17

Note:

By default, the delay time is 90s and the txontime is 10s.

For the ATM optical ports configured with the 1+1 port protection, do not enable the

ALS function.

II. Querying the ALS switch state

To query the state of the ALS switch, use the display als command.

huawei(config-if-aiu-0/7.optic)#display als

{ portid }:0

ALS is enable

Current ALS TxOn time: 50(second)

Current ALS delaytime: 100(second)

III. Manually sending optical detection signals

To manually send the optical detection signal, use the als-startup command.

7.4.14 Querying the Port Alarm State

When a port fails, use the display alarm command to query its alarm state. Based on

the alarm information, you can locate the fault.

7.5 Configuring the E3/DS3 Port

UA5000 provides E3 and DS3 ports through the AIUB card. Table 7–5 lists the

commands for configuring the E3/DS3 port.

7.5.1 Entering the E3/DS3 Port Mode

To enter the E3 mode, do as follows:

1) Use the interface aiu command to enter the AIU mode.

2) Use the sub-interface e3 command to enter the E3 mode.

To enter the DS3 mode, do as follows:

1) Use the interface aiu command to enter the AIU mode.

2) Use the sub-interface ds3 command to enter the DS3 mode.

Example

huawei(config)#interface aiu 0/7

huawei(config-if-aiu-0/7)#sub-interface

{ima|optic|e3/ds3 }:e3/ds3

Command:

sub-interface e3/ds3

huawei(config-if-aiu-0/7.e3/ds3)#

7.5.2 Setting a Port as UNI or NNI

To set a port as UNI or NNI, use the uni-nni-set command. By default, it is a UNI. When

two E3/DS3 ports are interconnected, their properties must be consistent.

The setting will take effect after the card is reset.

Note:

Delete all PVC and PVP configurations associated with the port before you set it as a

UNI or NNI.

7.5.3 Setting the Port Line Type

To specify the line type of an E3/DS3 port, use the linetype command.

Line types supported by both the E3 and DS3 ports are:

G.751 with PLCP encapsulation (e3Plcp)


22/84



7-19

G.751 without PLCP encapsulation (e3Framed)

G.832 (e3other )

Line types supported only by the DS3 port are:

ds3CbitAdm

ds3M32Adm

ds3CbitPlcp

ds3M32Plc

7.5.4 Setting the Port Tx Clock

To set the Tx clock of the E3/DS3 port, use the tx clock port { system | line} command.

The port Tx clock includes system clock and line clock.

System clockWhen the system clock is selected for the transmission port, the signals in the

transmission line will lock the TDM or SDH clock of the system. Use the system clock

when the peer network element is synchronized to the UA5000.

Line clock

When the line clock is selected for the transmission port, the clock extracted from the

receiving port will be sent back to the Tx clock. Use the line clock when the UA5000 is

synchronized to the peer network element.

7.5.5 Querying the Port Resources

To query the application resources of an E3/DS3 port, use the display resource

command. Port resources include the maximum number of VP and VC connections,

and so on.

7.5.6 Setting the maximum VPI Number for a VC Connection

To set the maximum VPI number for a VC connection, use the vpi-num-for-vcc

command.

7.5.7 Querying the Port Statistics

To query the statistics of an E3/DS3 port, use the display statistic command. The

statistics include Rx/Tx cells and bit error events of the E3/DS3 port.

7.5.8 Clearing the Port Statistics

To clear the statistics of an E3/DS3 port, use the clear statistic command.


23/84



7-20

7.5.9 Querying the Port Line State

To query the line state of an E3/DS3 port, use the display linestatus command. The

state can be basic line state or extended line state.

7.5.10 Querying the Interval Statistics

To query the statistics within different intervals for an E3/DS3 port, use the command

below:

display interval-statistics port { current-15minutes | last-24hours |

15minutes-Interval 15minutes-IntervalNo }

The parameters are described below:

current-15minutes means to query the statistics of current 15 minutes.

last-24hours means to query the statistics of current 24 hours.

15minutes-Interval means to query the statistics by the time interval (15

minutes).

15minutes-InvervalNo is the interval index (1–96).

The query interval is 15 minutes. So, the query times within 24 hours is 96

(24 × 60/15=96).

7.5.11 Setting the Loopback

To carry out the loopback test, use the loopback command.

To stop the loopback, use the undo loopback command.

Loopback test is a frequently used troubleshooting method. The E3/DS3 port supports

both local loopback and remote loopback.

In the local loopback, cells from the AIU card to the E3/DS3 port are sent back to

the AIUB card directly.

In the remote loopback, cells received by the E3/DS3 port are sent out directly and

do not pass through the AIUB card.

7.5.12 Querying the Configuration of a Card and Its Ports

To query the details of a card and its ports, use the display board command.

7.6 Configuring the IMA Port

The Inverse Multiplexing for ATM (IMA) de-multiplexes the ATM cell flow into multiple

low-speed links, and multiplexes them at the far end to reassemble the original ATM

cell flow. The IMA enables transmitting ATM cells over existing links (especially 2 Mbit/s

links).


24/84



7-21

The IMA technology includes multiplexing and demultiplexing ATM cells. The functional

group that performs the multiplexing and demultiplexing is called an IMA group. An IMA

group terminates at the end of each IMA virtual connection.

The UA5000 provides IMA interfaces through the E8IA subcard attached to the AIUcard.

Figure 7–2 shows the configuration procedure of the IMA service.

IMA ID

IMA protocol version

IMA frame length

Whether to enable CRC4

IMA group scramble

IMA group clock mode

Transmission clock

7.6.1 Entering the IMA Mode

Before configuration, enter the IMA mode.

Example

To enter the IMA mode of the AIU card at frame 0 slot 6, do as follows:

huawei(config-if-aiu-0/6)#sub-interface ima

huawei(config-if-aiu-0/6.ima)#

7.6.2 Adding an IMA Group

Use the following command to add an IMA group:

ima group add groupindex version mintxlinks minrxlinks { itc | ctc } imaid framelength

alpha_value beta_value gamma_value

In this command:

The IMA protocol version includes version 1.0 and version 1.1. IMA groups with

different versions cannot communicate with each other.


26/84



7-23

minTxLinks and minRxLinks indicate the minimum numbers of transmitted links

and received links respectively. One IMA group shall have at least one link. So, the

minimum link number shall be configured. These two parameter values are the

same. CTC and ITC refer to two types of clock modes. Common Transmit Clock (CTC)

means that the transmitting clocks of all links in the group lock the same clock

source. Independent Transmit Clock (ITC) means that the transmitting clocks of

links in the group lock different clock sources. When the IMA uses the system

clock, configure the CTC mode for the group clock. When the IMA uses the line

clock, configure the ITC mode for the group clock.

Framelength indicates the length of an IMA frame, that is, the number of cells one

IMA frame contains. The values include 32, 64, 128, and 256. Usually select 128.

alpha, beta and gamma are the status machine parameters of the IMA. When the

IMA link receives consecutively a certain number of frames of the specified type

(the number is specified by alpha_value, beta_value, and gamma_value

respectively), the status of IMA group will transfer.

The settings of an IMA group shall be consistent at both near end and far end. The links

of an IMA group at near end cannot be configured to two IMA groups at far end.

For example, to add an IMA group, do as follows:

huawei((config-if-aiu-0/6.ima)#ima group add 0 version1.1 2 2 ctc 0 128 2 2

1

Note:

One IMA subcard supports four IMA groups. Each group can be configured with one

to eight E1 links. Each E1 link can belong to only one IMA group.

One IMA group has one group index and one IMA ID. These two values are often

set to be the same.

7.6.3 Querying an IMA Group

To query the information about an IMA group, use the display ima group command.

I. Querying failure status of an IMA group

To query the failure status of an IMA group, use the display ima group fail-status

command. The queried information includes: failure status, near-end failure number

and far-end failure number.


27/84



7-24

II. Querying IMA group parameters

To show the parameters of an IMA group, use the display ima group parameter

command.

The queried parameters include:

Near end symmetry

Far end symmetry

Minimum transmitted links

Minimum received links

Near end clock mode

Far end clock mode

Transmission reference link

Receiving reference link

Transmission IMA ID

III. Querying running status of an IMA group

To query the running status of an IMA group, use the display ima group run-status

command.

The queried information includes:

Near end group status

Far end group status

Available transmission bandwidth

Available receiving bandwidth Tx config link count

Rx config link count

Tx active link count

Rx active link count

Test status

IV. Querying performance statistics of an IMA group

To query the performance statistics of an IMA group, use the following command:

display ima group performance-statistics groupId { total | current | interval

intervalIndex }


28/84



7-25


Unavailable duration

Near end failure number

Far end failure number

The following describes the parameters of this command.

total: to query the total performance statistics.

current: to query the current performance statistics.

interval: to query the performance statistics by time interval.

intervalIndex : interval index (0–95). The performance statistics interval is 15 minutes,

so, the measuring times in 24 hours is 96 (24 × 60/15 = 96). Therefore, the interval

index ranges 0–95.

Note:

Query the performance statistics and statistics status of the IMA group after you

configure the IMA links in the IMA group.

V. Querying the statistics status of an IMA group

To show the statistics status of an IMA group, use the display ima group

performance-status command.

7.6.4 Deleting an IMA Group

To delete an unused group, use the ima group delete command.

If the deleted IMA group has IMA links, the links will also be deleted at the same time.

When the IMA group has loopback or PVC connection, this IMA group cannot be

deleted.

After an IMA group is created, to modify the IMA ID or IMA frame length, you have to

delete this IMA group and then create a new one. At this time, the peer IMA group has

recorded the data of the previous IMA group, and cannot update it automatically. In this

case, use the ima group reset command at the peer end to reset the IMA group.


29/84



7-26

7.6.5 Setting the IMA Group Mode

I. Setting the clock mode

To set the clock mode of an IMA group, use the ima group mode clockmode{ groupindex | all } { line |system } command.

The clock of an IMA group can lock the line clock or system clock. By default, it locks

the system clock. When two IMA subcards are interconnected, the clock modes at both

sides shall be different.

II. Setting the CRC4 function

To set the CRC4 function of an IMA group, use the ima group mode crc4-multiframe

groupindex {off|on} command. By default, the CRC4 function is disabled.

The CRC4 function is to perform the CRC for E1 frame. Note the CRC4 setting whenthe UA5000 is interconnected with equipment of other manufacturers.

III. Setting the scramble function

To set the scramble function, use the ima group mode scramble groupindex {off|on}

command. By default, the scramble function is disabled.

Use the scramble function to avoid that the payload of ATM cell has the same digital

string as the cell header.

The settings of CRC4 and scramble functions shall be consistent at both ends of the

lines.

7.6.6 Blocking/Unblocking an IMA Group

To block an IMA group, use the ima group block groupId command. You cannot block

an IMA group if it has no link.

To unblock an IMA group, use the undo ima group block groupId command.

7.6.7 Enabling/Disabling IMA Group Loopback

To enable the loopback to an IMA group, use the ima group loopback command. Theloopback type includes local loopback and remote loopback.

To disable the loopback, use the undo ima group loopback command.

When the transmission clock of an IMA group is the line clock, do not configure the local

loopback for this group. When the IMA ID, IMA frame length and minimum link number

of two interconnected IMA groups are different, you cannot activate the IMA group after

the loopback.

7.6.8 Adding an IMA Link

The IMA service only supports the symmetrical working mode.


30/84



7-27

To add IMA links, use the ima link add groupindex linkid command.

In this command, linkid is the IMA link ID, ranging 0–7. Each IMA group supports up to

eight E1 links. Each E1 link can only belong to one IMA group.

7.6.9 Querying an IMA Link

To query the information about an IMA link, use the display ima link command.

I. Querying IMA link parameters

To query the IMA link parameters, use the display ima link parameter command.

II. Querying running status of an IMA link

To query the running status of an IMA link, use the display ima link run-status

command.

III. Querying performance statistics of an IMA link

To query the performance statistics about an IMA link, use the command bellow:

display ima link performance-statistics linkId {total | current | interval

intervalIndex }

The following describes the parameters of this command.

total: to query the total performance statistics.

current: to query the current performance statistics.

interval: to query the performance statistics by time interval.

intervalIndex : interval index (0–95).

IV. Querying the statistics status of an IMA link

To query the statistics status of an IMA link, use the display ima link

performance-status command.


Valid interval number

Invalid interval number

Past seconds

7.6.10 Setting the IMA Link Test

Use the ima link test activate command to test:

the transmitting/receiving status of the specified link

the receiving status of other links in the same group.

The relevant information is shown in alarms.

After the link test completes, the system will deactivate the test.


31/84



7-28

If exceptions occur during the test, you can use the undo ima link test activate

command to deactivate the test.

7.6.11 Blocking/Unblocking an IMA Link

You can block the IMA link in the transmitting or receiving direction or both directions.

To block the IMA link, use the ima link block linkid {tx | rx} command. To unblock the

IMA link, use the undo ima link block linkid {tx | rx } command.

7.6.12 Deleting an IMA Link

To delete links from an IMA group, use the ima link delete command.

However, you cannot delete a link if:

The IMA group of the link has loopback. The IMA group has PVC connection, and the bandwidth of the group is less than

the allocated bandwidth after the link is deleted.

The IMA group has PVC connection, and the number of links of this group is less

than the minimum numbers of received/transmitted links.

The link to be deleted is the last link in the IMA group.

To delete the last link in an IMA group, use the ima group delete command to delete it

together with the group.

To add a link to a new group after it is deleted from one group, both this NE link and FE

link in this group must be deleted and then added to the new group. Otherwise, the NEand FE will be inconsistent.

7.6.13 Querying the IMA Configuration

To query the IMA configuration, use the display ima config command.

The queried information includes the configurations and status of the IMA group and

link.

7.6.14 Configuring the PVC

Use the pvc command to create the PVC connection between the IMA group and other

ports.

When the PVC is created, the parameter frame/slot refers to the frame number/slot

number of the AIU board. The IMA group number is also needed.

7.6.15 Setting the Maximum Number of VPI for the VC Connections

Use the vpi-num-for-vcc command to modify the maximum number of VPI for the VC

connections of the IMA group. The number must be 2 to the power of n such as 1, 2,

4, …, 256.


32/84



7-29

Use the display resource command to show the existing maximum number of VPIs.

Example

To set the maximum number of VPI to 4, do as follows:

huawei(config-if-aiu-0/6.ima)#vpi-num-for-vcc 0 4

This operation may result in board reset, whether to continue? (y/n)[n]:y

Board resetting is under way...

Caution:

Modifying the maximum number of VPIs will result in the card reset.

7.7 Configuring the ADSL Port

The UA5000 supports multiple cards that can provide different types of ADSL ports and

ADSL services. See Table 7–7.

Table 7–7 The relation between ADSL cards and ADSL ports

ADSL Cards Description

ADLB Provides 16 ADSL ports and the ADSL over POTS service

ADLF Provides 16 ADSL ports and the ADSL over ISDN service

ADM Provides 16 ADSL2+ ports and the ADSL over POTS service

7.7.1 Querying the ADSL Port State

To query the ADSL port state, use the display port state command.

The state includes: activating, activated, deactivating and deactivated. Among them,the activating and deactivating states are transitional states.

By default, the ADSL port uses the default line profile 1, and the ADSL2+ port uses the

default line profile 1002. Once a port is connected with an ATU-R and the link between

ATU-R and ATU-C is normal, the port is activated.

7.7.2 Setting the ADSL Line Profile

Set the following parameters when you activate the ADSL port:

ADSL working mode

Channel mode

Upstream and downstream line rates

Signal to noise ratio (SNR) margin

Most of these parameters are the same for all the ATM ports. The ADSL line profile sets

these parameters. So, after the profile is configured successfully, the port can reference

it in the activation.

I. Adding the ADSL line profile

Use the adsl line-profile add command to add an ADSL line profile.

The UA5000 has four default profiles, with the profile indexes 1, 1000, 1001 and 1002.

Their functions are as follows:

Use profile 1 to activate the common ADSL port.

Use profile 1000 to activate the common ADSL port quickly.

Use profile 1001 to activate the long-distance ADSL port.

Use profile 1002 to activate ports on the ADSL2+ cards.

Parameters in the default profile are only for reference. You can change them if

necessary.

Figure 7–3 shows the configuration procedure for the ADSL line profile.

> Upstream channel bit swap 0-disable 1-enable (0~1) [1]:

4) Select the channel working mode.

> Please select channel mode 0-interleaved 1-fast (0~1) [0]:0

Input 0 to enable the interleaved mode, or 1 to enable the fast mode.

There are two channel modes: interleaved mode and fast mode. By default, the

interleaved mode is enabled. In the fast mode, the transmission delay of the ADSL

data is smaller than that in the interleaved mode, but the fast mode is less stable

than the interleaved mode. For the Internet access service, use the interleaved

mode. For delay sensitive services such as VOD, use the fast mode.

If you select the fast mode, you must set the SNR and the upstream and

downstream rate of the modem. If you select the interleaved mode, you must set

the interleaved parameters as follows.

5) Set the interleaved delay.

> Will you set interleaved delay? (y/n)[n]: y

Set the maximum downstream interleaving delay.

> Maximum downstream interleaved delay(0~255 ms) [16]:

Set the maximum upstream interleaving delay.

> Maximum upstream interleaved delay(0~255 ms) [6]:

6) Set the downstream rate adaptation mode.

> Please select form of transmit rate adaptation in downstream:

> 0-fixed 1-adaptAtStartup 2-adaptAtRuntime (0~2) [1]: 2

The mode includes fixed, adapt at startup and adapt at runtime. When the defaultparameter type is ADSL, only 0 and 1 are available. The downstream rate can be

trained in various situations.

Fixed: In this mode, the ADSL port is activated at the fixed downstream rate. The

rate must be the same as the maximum/minimum downstream rate set in the line

profile.

Adapt at startup: In this mode, the ADSL port sets up a connection at the best rate

based on the result of its training with the ATU-R. The rate falls in the range of the

maximum and minimum rates set in the profile.

Adapt at runtime: In this mode, the line rate is adjusted according to the line state.

If the line state deteriorates, lower the rate to enhance the stability of the

connection. If the line state is good, increase the line rate.

Note:

Only the ADSL2 or ADSL2+ supports adaptation at runtime. The ADSL does not

support this function.

7) Set the modem SNR margin.


39/84



7-36

> Will you set SNR margin for modem? (y/n)[n]: y

Select the default value generally. Input “N” to ignore the SNR margin of the

modem. Input “Y” to set the modem SNR margin.

In the line parameters, the SNR margin includes target SNR margin, maximum

SNR margin and minimum SNR margin.

SNR margin for a modem is directly proportional to the stability of the ADSL

connection. That is to say, the larger the SNR margin for the modem, the more

stable is the ADSL connection. However, the SNR margin is inversely proportional

to the bit rate of an activated physical connection. That is to say, the larger the

SNR margin, the lower is the activated physical connection rate.

To set the SNR margin, the system prompts the following information.

Set the target downstream SNR margin.

> Target SNR margin in downstream(0~15dB) [6]:

The target SNR margin refers to the noise margin reserved when the data

communication is normal. It is used to keep the communication normal if the line

noise deteriorates. The larger the SNR margin, the smaller is the possibility of a

system transmission error, and the safer is the system. However, the larger the

SNR margin, the smaller is the traffic flow, and the lower is the data transmission

rate.

After the target SNR margin is set, the ADSL creates the connection and

determine the physical rate of the connection based on this SNR margin.

Set the minimum downstream SNR margin.

> Minimum SNR margin in downstream (0~6 dB) [0]:

If the SNR margin is smaller than the minimum SNR margin, the system increases

the transmission power. After that, if the problem persists, reactivate the line.

Set the maximum downstream SNR margin.

> Maximum SNR margin in downstream (6~31 dB) [31]:

Use the default value 31 dB.

If the line SNR margin is larger than the maximum SNR margin, the system lowers

the transmission power.

Set the target upstream SNR margin.

> Target SNR margin in upstream (0~15 dB) [6]:

Set the minimum upstream SNR margin.

> Min. SNR margin in upstream (0–12 dB) [0]:

Set the maximum upstream SNR margin.

> Maximum SNR margin in upstream (6~31 dB) [31]:

8) Set the parameters for adaptation at runtime.

This step applies to only the ADSL2/ADSL2+ and the adaptation mode must be

adaptAtRuntime.


40/84



7-37

Set the SNR margin threshold for enabling the adaptAtRuntime function.

When the SNR margin reaches the limit for lowering or increasing the rates, the

adaptAtRuntime function is enabled.

> DownStream SNR margin for rate downshift (0~5 dB) [3]:

> DownStream SNR margin for rate upshift (7~31 dB) [9]:

> UpStream SNR margin for rate downshift (0~5 dB) [0]:

> UpStream SNR margin for rate upshift (7~31 dB) [12]:

Set the shift time for enabling the adaptAtRuntime function.

The system adjusts the line rate only when the SNR margin reaches the threshold

for enabling the adaptAtRuntime function and keeps the state for a period. The

period of time is the shift time.

> Will you set shifttime? (y/n)[n]: y

> Minimum Downshift time in downstream (0~16383 second) [60]:

> Minimum Upshift time in downstream (0~16383 second) [60]:

> Minimum Downshift time in upstream (0~16383 second) [0]:

> Minimum Upshift time in upstream (0~16383 second) [0]:

9) Set the rate parameters.

> Will you set parameters for rate? (y/n)[n]:Y

Input N to ignore the setting, or input Y to set the rate parameters.

The rate settings are related to the stability of the connection. Under the same

conditions, a very high rate results in an unstable connection. In general, the

default settings are recommended.

To set the rate parameters, the system prompts the following information.

Set the minimum downstream bit rate.

> Minimum bit rate in downstream (32~32000 Kbps) [32]:

If the calculated downstream rate is smaller than the minimum downstream rate,

the port is not activated.

To specify the fixed rate, set the minimum value the same as the maximum value.

Set the maximum downstream bit rate.

> Maximum bit rate in downstream (32~32000 Kbps) [24544]:

Set the minimum upstream bit rate.

> Minimum bit rate in upstream (32~3000 Kbps) [32]:

If the calculated upstream rate is smaller than the minimum upstream rate, the

port is not activated.

Set the maximum upstream bit rate.

> Maximum bit rate in upstream (32~3000 Kbps) [1024]:

10) Prompt the successful setting of the ADSL line profile.

After you set the upstream maximum bit rate and the ADSL line profile, the system

prompts the following message.


41/84



7-38

Add profile 2 successfully

The message contains the ADSL line profile index. Here, it is 2. The referencing

and deleting of this profile will be based on the profile index.

II. Querying the ADSL line profile

Use the display adsl line-profile command to query the ADSL line profile.

If you do not specify a profile index, the system lists the brief information about profiles.

The information contains:

Profile index

ADSL working mode

Channel working mode

Maximum and minimum upstream/downstream rates

If you specify a profile index, the system lists its detailed information. The information

includes interleaving delay, SNR margins and so on.

--------------------------------------------------------------------

III. Modifying the ADSL line profile

To modify the ADSL line profile, use the adsl profile modify command.


43/84



7-40

After you modify the ADSL line profile, the system displays the message that the new

configuration will take effect immediately.

Note:

If the modified profile has already been referenced by the port, the system uses the

modified parameters to activate the port again.

IV. Deleting the ADSL line profile

To delete the ADSL line profile, use the adsl profile delete command.

Note:

You cannot delete the ADSL line profiles 1, 1000, 1001 and 1002.

You can also not delete ADSL line profiles referenced by the port.

7.7.3 Setting the ADSL Alarm profile

You can use the ADSL alarm profile to set alarm thresholds, to count and supervise the

performances of an active ADSL line. Once the threshold exceeds the limit, the

UA5000 informs the equipment of the event, and sends alarms to the log host and the

NMS.

In practice, as most of the ports share the same settings, the UA5000 system provides

the ADSL alarm profile. After the profile is set successfully, use the alarm-config

command to bundle a port.

I. Adding an ADSL alarm profile

To add an ADSL alarm profile, use the adsl alarm-profile add command.

Note:

The UA5000 has its own ADSL alarm profile, with an index 1. By default, the ADSL port

is bound with this profile.
