Contents

These release notes describe the following topics:

Introduction

The Cisco uBR7200 series universal broadband routers—the Cisco uBR7223, the Cisco uBR7246, and the Cisco uBR7246 VXR—are based on the Data-over-Cable Service Interface Specification (DOCSIS) standards. Each is designed to be installed at a cable operator's headend facility or distribution hub and to function as the cable modem termination system (CMTS) for subscriber-end devices such as Cisco uBR904 and Cisco uBR924 cable access routers, and other DOCSIS-based cable modems (CMs) and set-top boxes (STBs).

Cisco uBR7200 series universal broadband routers allow two-way transmission of digital data and Voice over IP (VoIP) traffic over a hybrid fiber-coaxial (HFC) network. For cable plants not fully upgraded to support two-way cable transmission, the routers support DOCSIS-compliant telco return, where the cable modem's return path to the CMTS uses a dial-up telephone line connection instead of an upstream channel over the coaxial cable. The telco-return delivery mechanism enables cable operators to accelerate deployment of high-speed data services before the cable systems are upgraded to two-way plants.

These routers support IP routing with a wide variety of protocols and combinations of Ethernet, Fast Ethernet, Gigabit Ethernet, serial, High-Speed Serial Interface (HSSI), Packet over SONET (POS) OC-3 and OC-12c, and Asynchronous Transfer Mode (ATM) media. Additional protocols and media might be added as they become available for the Cisco uBR7200  series routers.

Cisco uBR7246 VXR Universal Broadband Router

The Cisco uBR7246 features an I/O controller, up to two network interface port adapters, up to four cable modem cards, a high-performance network processing engine, and up to two removable power supplies, providing load-sharing and redundancy capabilities. The Cisco uBR7246 VXR provides two PCMCIA slots that allow for software upgrades through the use of Flash memory cards.

Note   The Cisco uBR7246 VXR chassis does not support the MC11-FPGA cable modem card.

Cisco uBR7246 Universal Broadband Router

The Cisco uBR7246 features an I/O controller, up to two network interface port adapters, up to four cable modem cards, a network processing engine, and up to two removable power supplies, providing load-sharing and redundancy capabilities. The Cisco uBR7246 provides two PCMCIA slots that allow for software upgrades through the use of Flash memory cards.

Note   The original MC11 modem card (MC11-FPGA) is supported only on Cisco uBR7246 routers that are using the NPE-150 or NPE-200 processor cards.

Cisco uBR7223 Universal Broadband Router

The Cisco uBR7223 features an I/O controller, one network interface port adapter, up to two cable modem cards, a network processing engine, and a removable power supply. (The Cisco uBR7223 does not feature load-sharing and redundant power supply capability like the Cisco uBR7246 and Cisco uBR7246 VXR.) The Cisco uBR7223 provides two PCMCIA slots that allow for software upgrades through the use of Flash memory cards.

The Cisco uBR7223 is a cost-effective, scalable interface between subscriber cable modems and the backbone data network, and is designed specifically for small to medium network installations.

Note   The original MC11 modem card (MC11-FPGA) is supported only on Cisco uBR7223 routers that are using the NPE-150 or NPE-200 processor cards.

The table also provides a brief description of each MIB's contents and the Cisco IOS release in which the MIB was initially functional—earlier releases might have had unsupported prototype versions of the MIB; later releases might have added new attributes and functionality. Because of interdependencies, the MIBs must be loaded in the order given in the table.

Note   The names given in Table 5 are the filenames for the MIBs as they exist on Cisco's FTP site (ftp://ftp.cisco.com/pub/mibs/  or http://www.cisco.com/public/mibs) . Most MIBs are available in both SNMPv1 and SNMPv2 versions; the SNMPv1 versions have V1SMI as part of their filenames.

Deprecated MIBs

A number of older Cisco-provided MIBs have been replaced with more scalable, standardized MIBs; the MIBs have filenames that start with "OLD" and first appeared in Cisco IOS Release 10.2. The functionality of these MIBs has already been incorporated into replacement MIBs, but the old MIBs are still present to support existing Cisco IOS products or Network Management System (NMS) applications. However, because the deprecated MIBs will be removed from support in the future, you should update your network management applications and scripts to refer to the table names and attributes that are found in the replacement MIBs.

Table 6 shows the deprecated MIBs and their replacements. In most cases, SNMPv1 and SNMPv2 replacements are available, but some MIBs are available only in one version. A few of the deprecated MIBs do not have replacement MIBs; support for these MIBs will be discontinued when Cisco IOS software no longer supports the corresponding feature set.

Caveats

This section lists caveats that describe potentially unexpected behavior in Cisco IOS Release 12.1(4). Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious.

For information on additional caveats in Cisco IOS Release 12.1, see Caveats for
Cisco IOS Release 12.1 .

Note   If you have an account with CCO, you can use Bug Navigator Toolkit to find caveats of any severity for any release. You can reach Bug Navigator on CCO at Software Center: Tools: Software Bug Toolkit: Bug Navigator II or at http://www.cisco.com/support/bugtools.

Open Caveats—Release 12.1(4)

Other than the open caveats from earlier releases, there are no new open caveats in Release 12.1(4).

Closed and Resolved Caveats—Release 12.1(4)

Other than the closed and resolved caveats from earlier releases, there are no new closed and resolved caveats in Release 12.1(4).

Open Caveats—Release 12.1(2)

Other than the open caveats from earlier releases, there are no new open caveats in Release 12.1(2).

Closed and Resolved Caveats—Release 12.1(2)

Other than the closed and resolved caveats from earlier releases, there are no new closed and resolved caveats in Release 12.1(2).

Open Caveats—Release 12.1(1)

This section describes possibly unexpected behavior by Release 12.1(1) and describes only severity 1 and severity 2 caveats:

  Under certain conditions, PA-2FE port adapters might start dropping packets at very high throughput rates, such as 65 Mbps, when transmitting downstream traffic. The workaround is to reduce the flow of data until the errors stop.

Closed and Resolved Caveats—Release 12.1(1)

This section describes caveats resolved in Release 12.1(1) and describes only severity 1 and 2 caveats:

  The DOCS-IF-MIB.my MIB has been updated to be compliant with RFC 2670, which defines the DOCSIS RF Interface MIB structure. To access the new structures, use a DOCS-IF-MIB.my file with a LAST-UPDATED field of "9908190000Z" (or later). Some of the attributes in this MIB refer to modem error counters that are not yet implemented—these attributes are in the "docsIfCmtsCmStatusTable" table and currently return zero (this feature is being tracked in CSCdm70870).
  Also, the "docsIfSigQEqualizationData" object returns an empty string; this is being tracked in CSCdp35567.
  When a cable modem card is replaced using online insertion and removal (OIR), the upstream and downstream channel information is missing from the DOCS-IF-MIB for that modem card and all cable modem cards below it. This is resolved in Cisco IOS Release 12.1(1).
  If you entered the show cable flap-list command while baseline privacy was active, the router reloaded. There was no workaround. This is resolved in Release 12.1(1).
  The cable source-verify dhcp command does not function properly when baseline privacy interface (BPI) is active. There was no workaround. This is resolved in Release 12.1(1).
  Swapping an unsupported cable modem line card in a Cisco uBR7200 chassis with a supported line card several times might cause the router to reload the routine to add a subinterface entry in the "ifTable".
  For example, if an OIR was performed to replace the MC11 FPGA (not supported) with the MC12C (supported) in the Cisco uBR7246 VXR, and the cards were swapped several times, the subinterface entry routine sometimes reloaded. This is resolved in Cisco IOS Release 12.1(1).
  Configuring a downstream channel ID on a cable interface caused the cable modems to hang up waiting for valid channel MAPs. In this state, CMTS was sending MAPs; however a stale parameter in the MAP messages caused the cable modems to ignore these MAPs. The workaround was to issue a clear interface on the CMTS after configuring the downstream channel ID. This caused the MAPs to refresh and pick up the latest Upstream Channel Descriptor (UCD) change count parameter. This is resolved in Cisco IOS Release 12.1(1).
  Issuing the show cable flap-list command at the CLI randomly crashed the Cisco uBR7200 series router. Pausing the screen display using the "--More--" feature increased the probability of a crash. The only workaround was to not use the show cable flap-list command. Instead, you could use SNMP to request the "ccsFlapObjects" attribute from the CISCO-CABLE-SPECTRUM-MIB.my MIB. This is resolved in Cisco IOS Release 12.1(1).
  Images with the recent upstream throughput enhancement could crash under certain specific upstream configuration and timing state conditions. This might occur if the upstream port was configured with non-default upstream parameters that caused a single request opportunity to span more than 1 minislot. A configurations that could cause this was:
  If the upstream channel was using a non-default setting like the one described above, the following timing conditions might trigger a reload:
  Even if there was no console activity, it was possible (under very rare timing conditions) for problems to occur. This is resolved in Cisco IOS Release 12.1(1).
  The Cisco uBR7200 series occasionally rebooted itself. A sample error message for a reboot is shown below:
    router1 uptime is 3 days, 8 hours, 34 minutes System returned to ROM by bus error at PC 0x60276FFC, address 0x80000D at 20:19:54 GMT Thu Jan 20 2000 System restarted at 20:21:27 GMT Thu Jan 20 2000 System image file is "slot0:ubr7200-k1ps-mz.120-8.SC.bin"

    0x60276FFC:cmts_delete_sid_state(0x60276fa8)+0x54 

  For earlier releases, it was necessary to enter the show context command. The output of this command reveals the context of the most recent crash. This is resolved in Release 12.1(1).





  Under certain rare circumstances, cable modem entries could exist on multiple interfaces, if the modem was moved from one interface to another and certain timing conditions were met. In some rare conditions when cable bundling was used, it caused loss of connectivity for the modems in question.


  The workaround was to disconnect the cable to the cable modem, and clear the cable modem status using a clear cable modem mac-address reset before moving it to another interface. This is resolved in Release 12.1(1).





  This problem exists only on uBR7200-ik1st-mz images.


  If there was a device connected to a non-cable interface on the Cisco uBR7200 series router, and if the Cisco uBR7200 acted as the DHCP relay agent or as the DHCP server for this device, the system might crash when a DHCP reply was sent to it.


  The workaround was to not use a Cisco uBR7200 as DHCP relay agent or as DHCP server for devices on non-cable interfaces. This is resolved in Release 12.1(1)





  On a CM registration, if the CMTS already had an entry for the CM, it did not update the IP address field to reflect the real CM IP address. This happened only if the Cisco IOS internal DHCP server was used. This is resolved in Release 12.1(1).





  The Spectrum Management task consumed a large amount of CPU cycle and caused CPU utilization to go up. This is resolved in Release 12.1(1).





  The CMTS was not protected against cable modems that exhibited non-DOCSIS-compliant behavior at initial ranging. Some modems on an upstream port might range with a negative timing offset. These modems might deceive the CMTS MAP-building code into using a large map-advance when the dynamic map advance algorithm (default) was active on each upstream port. This prevented all other modems on that upstream port from sending data upstream to the CMTS and they went offline. This is resolved in Release 12.1(1).




 A new CLI command, cable map-advance, was added to configure the static map-advance on each cable interface on the Cisco uBR7200. In addition, a new warning log message is generated every time a modem with a bad timing offset problem is detected by the CMTS. A sample message is shown below:


%UBR7200-5-BADTXOFFSET: Bad timing offset -10 detected for cable modem 0010.9500.0a6a
