Microcode SoftwareThis section describes microcode software that is supported for the Cisco uBR10012 router.

SPA FPD Image Packages for the Cisco uBR10012The field-programmable device (FPD) image packages are used to update the shared port adapter (SPA) FPDimages. If a discrepancy exists between a SPA FPD image and the Cisco IOS image that is running on therouter, the SPA is deactivated until this discrepancy is resolved.

The maximum time to upgrade the FPD image on one SPA is 2 minutes. The total FPD upgrade timedepends on the number of SPAs.

Note

The FPD image package that is used to upgrade SPAs on a router that runs Cisco IOS Release 12.2(33)SCJis the ubr10k-fpd-pkg.122-33.SCJ pkg file.

Feature SupportCisco IOS software is packaged in feature sets that consist of software images that support specific platforms.The feature sets available for a specific platform depend on which Cisco IOS software images are includedin a release. Each feature set contains a specific set of Cisco IOS features.

Cisco IOS images with strong encryption (including, but not limited to 168-bit [3DES] data encryptionfeature sets) are subject to U.S. government export controls and have limited distribution. Strong encryptionimages to be installed outside the United States are likely to require an export license. Customer ordersmay be denied or subject to delay because of U.S. government regulations.When applicable, the purchaseror user must obtain local import and use authorizations for all encryption strengths. Please contact yoursales representative or distributor for more information, or send an e-mail to [email protected].

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.

• 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.


IntroductionLimitations and Restrictions

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

• 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 modeconfiguration 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 interfaces


IntroductionSoftware Feature Restrictions

occurs 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.
