Cable Interface Line Cards Supported

Table 1-2 provides information about the supported cable interface line cards and processor engines in Cisco IOS Release 12.2(33)SCH.

OIR of Cable Interface Line Cards on the Cisco uBR10012 Universal Broadband Router

The Cisco uBR10012 series universal broadband routers support online insertion and removal (OIR) of cable interface line cards only when exchanging cable interface line cards of the same type.

Effective with Cisco IOS Release 12.2(33)SCC, OIR compatibility between the Cisco uBR10-MC5X20 and the Cisco UBR-MC20X20V line cards is supported. The OIR compatibility procedure translates the configuration from one format to another during the OIR process.

Prerequisites for Performing OIR

• Save the line card configuration before starting the OIR.

• Perform OIR when the CMTS is up and running.

• Change the standby card (if available) to HOT state.

• Save the startup configuration file before any reload of the system (if there is a need to reload), after a successful OIR.

Restrictions During OIR Process

Note The Cisco uBR-MC3GX60V line card does not support OIR compatibility. To upgrade to the Cisco uBR-MC3GX60V line card from the Cisco uBR10-MC5X20H or Cisco UBR-MC20X20V line cards, you must remove the existing configuration of the line card using the no card command and create a new configuration for the Cisco uBR-MC3GX60V line card.

• OIR upgrade cannot be performed when the standby PRE is being loaded.

• OIR downgrade from the Cisco UBR-MC20X20V line card to the Cisco uBR10-MC5X20 line card may fail in certain scenarios when the frequency and RF power settings on the Cisco UBR-MC20X20V line card are incompatible with the Cisco uBR10-MC5X20 card.

Performing an OIR of a Cable Interface Line Card

Step 1 In global configuration mode, enter the cr10k card oir-compatibility command for the cable interface line card to perform an OIR, as shown in the following example:

Router(config)# cr10k card 8/0 oir-compatibility

This command helps preserve the configuration and performs some internal synchronization to make sure that the OIR runs successfully.

Table 1-2 Supported Cable Interface Line Cards and Processor Engines

Supported Line Card Supported Processor Engine

Cisco UBR-MC20X20—maximum 8 PRE4, PRE5

Cisco uBR-MC3GX60V—maximum 8 PRE4, PRE5



Note Effective with Cisco IOS Release 12.2(33)SCC, OIR compatibility is automatically ON for all slots of the line cards.

Step 2 Save the configuration to ensure the transition, as shown in the following example:

Router# copy running-config startup-config

Step 3 Turn the power off to the line card using the cable power off command for the slot that is being replaced, as shown in the following example:

Router# cable power off 8/0 Line Card 8/0 is POWERED OFF

This powers off the line card gracefully.

Step 4 Before removing the card, verify that the proper grounding instructions have been followed for the card.

Step 5 Remove the line card.

Step 6 Replace it with the new line card in the slot.

Step 7 Enter the cable power on command to power up the line card, as shown in the following example:

Router# cable power on 8/0

Step 8 Enter the show interface cable command and verify that the card and line protocol is “up” as shown in the following example:

Router# show interface cable 8/0/0

Cable8/0/0 is up, line protocol is up Hardware is BCM3210 ASIC, address is 000a.13e8.1ca8 (bia 000a.13e8.1a60) Internet address is 10.1.1.3/24 MTU 1500 bytes, BW 27000 Kbit, DLY 1000 usec, rely 255/255, load 1/255 Encapsulation, loopback not set, keepalive not set ARP type: ARPA, ARP Timeout 04:00:00 Last input 4d07h, output 00:00:00, output hang never Last clearing of "show interface" counters never Queuing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 1834000 bits/sec, 2385 packets/sec 5 minute output rate 1982000 bits/sec, 2431 packets/sec 24461542 packets input, 2348214388 bytes, 0 no buffer Received 1979 broadcasts, 0 runts, 0 giants, 0 throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 24854257 packets output, 2536222931 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out

Step 9 Enter the show controllers cable command and verify the hardware status, as shown in the following example:

Router# show controllers cable 8/0/0Cable8/0/0 JIB hardware status: JIB Downstream port Enabled JIB Upstream port 0 Enabled JIB Upstream port 1 Enabled JIB Upstream port 2 Enabled JIB Upstream port 3 EnabledCable8/0/0 Upconverter is Enabled Output is Enabled Model: 74-3153-02 Serial Number: 0WAV090200A1 CLEI Code: FFFFFFFFFF HW Rev: PC2D0109 SW Rev: 203, NVRAM Rev: 021 ECI numb



Note To verify the hardware status of the Cisco UBRMC20X20V cable line cards, it is recommended that you run the show controller integrated-cable 8/0/0 brief command instead of the show controllers cable command.

Step 10 Verify the configuration with the show running-configuration command.

Other Hardware Supported

Table 1-3 provides information about other hardware supported in Cisco IOS Release 12.2SC.

Verifying the Software VersionTo determine the version of the Cisco IOS software running on your Cisco universal broadband router, log in to the router and enter the show version EXEC command:

Chapter 1 IntroductionMIBs

Physical Channel Interface Mapping

This feature provides an SNMP interface to access information between the physical channel interface and the primary channel interface. The following MIB objects of the CISCO-DOCS-EXT-MIB object can be queried for information about the physical channel interface and the primary channel interface.

• cdxRFtoPrimaryChannelMappingTable

• cdxPrimaryChanneltoRFMappingTable

For more information, see Cisco CMTS Universal Broadband Router Series MIB Specifications Guide 12.2SC at:


Reload PXF in the Standby PRE Periodically

Reload PXF in the Standby PRE feature fixes most of the double-hit IRAM parity errors by reloading the Parallel Express Forwarding (PXF) in the standby PRE. The PXF can be reloaded periodically, or by a process based on timeout events, in the standby PRE.

The following new command was added:

periodic rel-pxf enable

http://www.cisco.com/en/US/products/hw/cable/ps2209/prod_eol_notices_list.html

Software Feature RestrictionsThis section describes other important guidelines or restrictions to consider when running Cisco IOS Release 12.2SC that might not yet be documented in the supporting customer documentation.

DOCSIS 3.0 Load Balancing

Note Effective with Cisco IOS Release 12.2(33)SCG1, the Cisco uBR-MC3GX60V line card and up to five Cisco Wideband SPAs can be configured to the same LBG.

DOCSIS

• You cannot configure a US connector to more than one fiber node.

• Multicast over DOCSIS L2VPN does not work for a DOCSIS 3.0-bonded cable modem (CM) when DOCSIS L2VPN is provisioned on a DOCSIS 3.0-bonded CM and downstream multicast traffic is sent over L2VPN. You can use a DOCSIS L2VPN classifier to classify multicast traffic on a secondary DS service flow with SF attributes (TLV 25.31/32) specifying primary DS for the CM. As a result, L2VPN multicast traffic uses the primary DS and L2VPN unicast traffic is forwarded over the primary bonding group. The service flow attribute feature is available in Cisco IOS Release 12.2SCB.


http://www.cisco.com/en/US/products/hw/cable/ps2209/prod_eol_notices_list.html

Chapter 1 IntroductionLimitations and Restrictions

DTI Card Configuration

The Cisco uBR10012 universal broadband router TCC card does not work as expected when the startup configuration contains the configuration for a Cisco uBR10012 universal broadband router TCC+ card. To fix this issue, use the no card slot/subslot 2cable-tccplus command and then configure the DTI card.

MIBs Restrictions

• IP-MIB is implemented as read-only. Writing is not supported for ipv6IPForwarding or ipv6IpDefaultHopLimit.

• docsIf3MdCfgMcastDsidFwdEnabled object is implemented as read-only.

• cdxBWQueueMaxDepth object sometimes reports a value out of range. The supported range is from 0 to 64, but the object sometimes returns a value of 128 when queried.

PacketCable

Payload Header Suppression (PHS) is not supported on wideband Embedded Media Terminal Adapters (eMTAs) for dynamic downstream service flows.

PXF

Statistics for two different divert-rate limit (DRL) WAN-IP streams can momentarily overlap or collide and produce statistics that are lower than expected.

Redundancy

• Longer dropout times (about 6 seconds) can occur when you use the OIR method to trigger a cable line card switchover on the Cisco uBR10012 router. To repair or maintain a cable line card and get better switchover performance, use the redundancy linecard-group switchover command to trigger the line card switchover instead.

• Although the software does not prevent it, preconfiguring commands on a protect line card is not supported.

• A dynamic service-flow for a PacketCable call is not deleted during a line card switchover.

• Although the Cisco CMTS router is initially configured only for global N+1 redundancy, the show running-configuration command displays both global and legacy interface-level Hot-Standby Connection-to-Connection Protocol (HCCP) configuration when you change the redundancy mode configuration from SSO to RPR mode. If you switch back to SSO mode, both redundancy configurations are still shown.

• In very rare circumstances, after an N+1 switchover, upstream traffic that is using Baseline Privacy Interface (BPI) encryption is not received properly by the CMTS router. Input errors are logged on the interface and the debug cable error command shows error messages similar to the following:

Cable5/1/4: Bad rx packet. JIB status code 0xA

The issue occurs on upstream channels that use a shared connector, where the other upstream channel using the same shared connector is on another downstream and is shutdown. To workaround this issue, you can activate the downstream and other upstream channel using the same shared connector or temporarily unshare the upstream connector.


Chapter 1 IntroductionImportant Notes

Wideband

If you configure a wideband interface with more than one MAC domain host sharing the committed information rate (CIR) bandwidth, then the total wideband interface CIR bandwidth gets fragmented among the MAC domain (MD) hosts sharing the wideband interface CIR bandwidth.

The WB interface CIR bandwidth can be shared by multiple MAC domain hosts, and these MAC domain hosts could potentially be on the same or different cable line cards. As admission control for WB interfaces occurs on cable line cards, the available CIR bandwidth gets partitioned and is given to the MD hosts causing the bandwidth fragmentation. However if a typical service flow CIR is very small compared to the total CIR of the wideband interface, then this fragmentation is not visible until the CIR usage reaches very high levels close to the total interface bandwidth.

With certain bandwidth percentage configuration and traffic distribution, the overall link utilization of dynamic bandwidth sharing (DBS) can be as low as 85 percent. For example, this can occur if the traffic rate on a wideband interface is smaller than its configured bandwidth percentage, but the traffic rate on a modular-cable interface is much larger than its bandwidth percentage. The packet drops occur only on the modular-cable interface which has a larger amount of traffic than its bandwidth-percentage. To workaround this scenario, configure a higher bandwidth percentage to the modular-cable interface, which is larger than or equal to its expected or average traffic rate.

CSCuc81226 A vulnerability in the implementation of the Network Time Protocol (NTP) feature in Cisco IOS Software could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition.

The vulnerability is due to the improper handling of multicast NTP packets that are sent to an affected device encapsulated in a Multicast Source Discovery Protocol (MSDP) Source-Active (SA) message from a configured MSDP peer. An attacker could exploit this vulnerability by sending multicast NTP packets to an affected device. Repeated exploitation could result in a sustained DoS condition.

Cisco has released free software updates that address this vulnerability. A workaround is available to mitigate this vulnerability.

This advisory is available at the following link:

Open Caveats—Cisco IOS Release 12.2(33)SCH

Bug ID Description

CSCue98698 On ESR-PRE2, "DUAL_CLEANUP_ATTEMPT" and "CM_INCONSISTENCY" error messages are displayed with tracebacks.

CSCud59107 On Cisco MC3GX60V line card, when fiber cable and Small Form-Factor Pluggable (SFP) (into active port) are plugged in at the same time, Traffic does not revert back to the active port.


CSCug78143 When docsIfCmtsServiceAdminStatus is set by SNMP, the line card crashes.

CSCuf51415 DOCSIS 2.0 modems become offline. "SINGLE_BIT_SEU_INT" error is seen before the modems become offline.

CSCuf95038 After a Cisco uBR-MC3GX60V line card switches over and reverts back during high availability operation, the narrowband modems connected to a random interface, drop offline. This also occurs during a high availability switch over. This behavior is observed when there is high upstream utilization.


CSCug18771 On Cisco 10012 router with Cisco uBR-MC3G60V line card using BRCM3142 chip, the upstream modulation error ratio (MER) is limited to 36.12 dB is observed.

CSCud46092 PRE4 on Cisco uBR10012 router running Cisco IOS Release 12.2(33) SCF3 crashes with the "%SYS-6-STACKLOW: Stack for process C10K card_oir_up_action_process running low, 0/6000" error message.


CSCud66175 When negative operation like reload, shutdown and no card are run on shared port adapter (SPA), then the PRE crashes.
















CSCud85809 When a SNMP polling script is used to poll SNMP objects with a large number of online cable modems, CPU Hog occurs with DTCC card and line card crash.



CSCuc95266 When N+1 Redundancy is activated for Cisco uBR-MC3Gx60V or Cisco uBR-MC20X20V line cards, the working line card crashes and normal operation is assumed by the protect line card.


CSCug00938 When single step ISSU changeversion is run, "%ISSU_PROCESS-7-DEBUG: % peer is not in terminal state" and "% issu changeversion failed to execute issurunversion'"errors occur.'

CSCug48008 When a script is run to reset the Cisco uBR_MC3GX60V line card using te hw-module slot 7 reset command.


CSCue02932 Rendezvous Point (RP) CPU usage spikes to 99% as IP Input process causes a spike of about 65%, because of the high channel change rate per cable modem.

CSCuf38527 On narrowband cable modems enabled with Multicast DSID Forwarding (MDF) enabled, when Video over DOCSIS (VDOC) load balancing feature moves cable modems on different channels, the cable modems stop receiving multicast traffic. If MDF is disabled, the cable modems receive multicast traffic again.

CSCue57085 The Cisco uBR-MC3GX60V line card crashes at cmts_hccp_delete_inter_pkt_cfr_loc(0x250df50)+0xf8.

CSCuf64911 Invalid cable modem status events are recorded in the logs when a cable modem sends two Timing, Communication, and Control records in the registration acknowledgement (REG-ACK) messages during an upstream partial service.

CSCuf71169 A cable interface line card may crash if a cable modem is reset periodically after enabling downstream resiliency.

CSCug66273 The Cisco uBR-MC3GX60V line card may crash when a 20-channel wideband interface is configured on a MAC domain.

CSCue48390 The SNMP agent reports channel information from the line card switchover state even after the cable modems are reverted to the original line card.

CSCuf81108 The route processor crashes if the spectrum management group with the start time and end time is deleted more than two times.

CSCue15313 Under certain conditions, Cisco uBR 10000 Series router configured for IPv4/IPv6 dual stack may be vulnerable to unauthenticated, adjacent attacker to trigger the reload of the routing engine on the affected device. Other configured IPv6 services, like DHCPv6, may additionally trigger such a reload.

CSCuf15414 The route processor may crash when modifying a cable filter group.















CSCuf56496 During replacement of configuration, the PRE crashes.

CSCug14057 The Cisco uBR-MC3GX60V protect line card goes down without any crash or log if the member subslot command is used with the protect keyword.
