Battery Backup 1x1 ModeCisco CMTS supports downgrading the channel bonding for cable modems and media terminal adapters(MTAs) in battery backup mode. When this feature is enabled and the cable modem enters the battery backupmode, channel bonding is downgraded to one downstream and one upstream channels (battery backup 1x1mode). This feature reduces the power usage when the cable modem is running on battery backup. When thecable modem returns to the AC power mode, the channel bonding is returned to its original configuration.

The following commands were introduced:

• cable reduction-mode mta-battery

• show cable modem reduction-mode mta-battery

IntroductionNew Software Features in Cisco IOS Release 12.2(33)SCI






D30 Dynamic Load BalancingEffective with Cisco IOS Release 12.2(33) SCI, the DOCSIS 3.0 dynamic load balancing can be activated onthe downstream channels using the cable load-balance docsis30-dynamic-enable command. The DOCSIS3.0 dynamic load balancing is based on the utilization method. It is used to balance the traffic across the QAMchannels per load balance interval.

The following commands were introduced or modified:

• cable load-balance docsis30-dynamic-enable

• clear cable load-balance error-statistics

• show cable load-balance docsis-group

• show cable load-balance

For more information, see the Load Balancing, Dynamic Channel Change, and Dynamic Bonding Changeon the Cisco CMTS Routers guide at the following URL:


Bidirectional Forwarding DetectionEffective with Cisco IOS Release 12.2(33) SCI, the Bidirectional Forwarding Detection (BFD) functionalityis supported on the Cisco uBR10012 router.

BFD is a detection protocol designed to provide fast forwarding path failure detection times for all mediatypes, encapsulations, topologies, and routing protocols. BFD also provides a consistent failure detectionmethod for network administrators. Because the network administrator can use BFD to detect forwarding pathfailures at a uniform rate, rather than the variable rates for different routing protocol hello mechanisms, networkprofiling and planning is easier, and re-convergence time is consistent and predictable.

The Cisco uBR10012 router has the following restrictions for BFD:

• BFD supports only four sessions on the Cisco PRE5. The performance of the PRE5 is affected, if morethan four BFD sessions are configured.

• On Cisco uBR10012 router, when multiple Intermediate System-to-Intermediate System (IS-IS) BFDsessions are configured on the interface and if all the interfaces are down at the same time, the IS-ISdoes not work as expected and the traffic loss is more than five seconds. This is because the adjacencyon the Cisco uBR10012 router is rebuilt slowly and takes more than five seconds to send packets.

• During PRE HA, OIR, PRE crash, or switchover, the performance of the Cisco uBR10012 router cannotbe maintained, if the BFD is configured on the Cisco 5-Port Gigabit Ethernet SPA or Cisco 1-Port10-Gigabit Ethernet SPA instead of Backhaul (BH) interface.

• If the default interface x/y/z is configured immediately after the BFD sessions are removed using theno bfd template command, there could be some issues, as the no bfd template command may not syncwith the standby PRE quickly.Cisco recommends that you have a time delay of more than two secondsbefore you configure the BFD sessions again.

• The Cisco uBR10012 does not identify BFD echo packets when the RPF is enabled. If you configurethe RPF on the interface, the BFD sessions are blocked and the packets are dropped.

• On the Cisco uBR10012 router, BFD does not support the MIB objects.


IntroductionNew Software Features in Cisco IOS Release 12.2(33)SCI



• On the Cisco uBR10012 router, BFD does not support multi-hop session.

• For non-ECMP routes, the traffic is delayed by more than 10 seconds, if you perform the OIR of anactive PRE. The current active PRE should recalculate the routes after the interfaces are up. In suchcases, Cisco recommends that you perform the PRE switchover before performing the OIR of the activePRE.

• The BGP network does not support NSR. Therefore, during the PRE HA, OIR, PRE crash, the BFDsessions might be down and would impact the traffic by more than two seconds.

Limitations and RestrictionsThis section describes restrictions for the Cisco universal broadband routers in Cisco IOS Release 12.2(33)SC.

Unsupported HardwareFor a list of unsupported hardware, see the End-of-Life and End-of-Sale Notices at:

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 Release12.2SC that might not yet be documented in the supporting customer documentation.

DOCSIS 3.0 Load Balancing

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

Note

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


IntroductionNew and Changed MIB Information in Cisco IOS Release 12.2(33)SCI1a

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

• Multicast over DOCSIS L2VPN does not work for a DOCSIS 3.0-bonded cable modem (CM) whenDOCSIS L2VPN is provisioned on a DOCSIS 3.0-bonded CM and downstream multicast traffic is sentover L2VPN. You can use a DOCSIS L2VPN classifier to classify multicast traffic on a secondary DSservice flow with SF attributes (TLV 25.31/32) specifying primary DS for the CM. As a result, L2VPNmulticast traffic uses the primary DS and L2VPN unicast traffic is forwarded over the primary bondinggroup. The service flow attribute feature is available in Cisco IOS Release 12.2SCB.

DTI Card ConfigurationThe Cisco uBR10012 universal broadband router TCC card does not work as expected when the startupconfiguration contains the configuration for a Cisco uBR10012 universal broadband router TCC+ card. Tofix 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 oripv6IpDefaultHopLimit.

• docsIf3MdCfgMcastDsidFwdEnabled object is implemented as read-only.

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

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

PXFStatistics for two different divert-rate limit (DRL) WAN-IP streams can momentarily overlap or collide andproduce 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 linecard switchover on the Cisco uBR10012 router. To repair or maintain a cable line card and get betterswitchover performance, use the redundancy linecard-group switchover command to trigger the linecard switchover instead.

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

• 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 showrunning-configuration command displays both global and legacy interface-level Hot-StandbyConnection-to-Connection Protocol (HCCP) configuration when you change the redundancy mode


IntroductionSoftware Feature Restrictions

configuration from SSO to RPRmode. If you switch back to SSOmode, both redundancy configurationsare still shown.

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

Cable5/1/4: Bad rx packet. JIB status code 0xAThe issue occurs on upstream channels that use a shared connector, where the other upstream channel usingthe same shared connector is on another downstream and is shutdown. To workaround this issue, you canactivate the downstream and other upstream channel using the same shared connector or temporarily unsharethe upstream connector.

WidebandIf you configure a wideband interface withmore than oneMAC domain host sharing the committed informationrate (CIR) bandwidth, then the total wideband interface CIR bandwidth gets fragmented among the MACdomain (MD) hosts sharing the wideband interface CIR bandwidth.

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

With certain bandwidth percentage configuration and traffic distribution, the overall link utilization of dynamicbandwidth sharing (DBS) can be as low as 85 percent. For example, this can occur if the traffic rate on awideband interface is smaller than its configured bandwidth percentage, but the traffic rate on a modular-cableinterface is much larger than its bandwidth percentage. The packet drops occur only on the modular-cableinterface 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 itsexpected or average traffic rate.
