Release Notes for Cisco uBR Advanced RF Switch

First Published: October 1, 2012

Introduction

This release notes contains new and changed information, hardware support, limitations and restrictions, and caveats for Cisco uBR Advanced RF Switch (Cisco UBR-RFSW-ADV).

The Cisco UBR-RFSW-ADV provides N+1 line card redundancy switching for the Cisco uBR10012 universal broadband router. The Cisco UBR-RFSW-ADV is a rack-mount unit controlled by the Cisco uBR10012 router.

The Cisco UBR-RFSW-ADV is located between the Cisco uBR10012 router and the cable plant. All the Cisco uBR10012 RF downstream (DS) and RF upstream (US) ports are connected to one side of the Cisco UBR-RFSW-ADV while the cable plant is connected to the other side.

Unlike the Cisco uBR 3x10 RF Switch, which uses Cisco RF Switch logic, and a Simple Network Management Protocol (SNMP) control interface to communicate with the Cisco uBR10012 router or the Cisco uBR7246VXR router, the Cisco UBR-RFSW-ADV is controlled by the Cisco uBR10012 router.


NoteAll Cisco UBR-RFSW-ADV configurations are executed on the Cisco uBR10012 Router.


For software caveats that apply to the Cisco IOS Release 12.2(33)SCG on the Cisco uBR10012 router, see the corresponding release notes for Cisco uBR10012 Router.

Feature Support

Cisco 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 included in a release. Each feature set contains a specific set of Cisco IOS features.


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

Cisco Feature Navigator

The Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or by feature set (software image). Under the release section, you can compare Cisco IOS software releases side-by-side to display both the features unique to each software release and the features that the releases have in common.

To access the Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check verifies that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password is e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

The Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

MIBs

To locate and download MIBs for selected platforms, Cisco IOS releases, and feature sets, use Cisco MIB Locator found at the following URL:

http://tools.cisco.com/ITDIT/MIBS/servlet/index

If Cisco MIB Locator does not support the MIB information that you need, you can also obtain a list of supported MIBs and download MIBs from the Cisco MIBs page at the following URL:

http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml

To access Cisco MIB Locator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check verifies that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password is e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions found at this URL:

For information about the MIBs supported by the Cisco universal broadband routers, see the Cisco CMTS Universal Broadband Series Router MIB Specifications Guide.

Caveats

This section describes open and resolved severity 1 and 2 caveats and select severity 3 caveats:

  • The "Open Caveats" sections list open caveats that apply to the current release and may apply to previous releases. A caveat that is open for a prior release and is still unresolved applies to all future releases until it is resolved.
  • The "Resolved Caveats" sections list caveats resolved in a specific release, but open in previous releases.

The bug IDs are sorted alphanumerically.


NoteThe Caveats section includes the bug ID and a short description of the bug. For details on the symptoms, conditions, and workaround for a specific caveat you must use the Bug Search Tool.


Cisco Bug Search

Cisco Bug Search Tool (BST), the online successor to Bug Toolkit, is designed to improve effectiveness in network risk management and device troubleshooting. You can search for bugs based on product, release, and keyword, and aggregates key data such as bug details, product, and version. For more details on the tool, see the help page located at http://www.cisco.com/web/applicat/cbsshelp/help.html .

Open Caveats

Bug ID
Description

CSCtz34632

The CMTS displays SWITCHCARD_CHANGE message that does not clearly state if the cable is disconnected and/or if it is a communication failure between the CMTS and the Cisco UBR-RFSW-ADV.

CSCtz55097

Disabling the Cisco UBR-RFSW-ADV causes traceback on the standby PRE.

CSCtz63656

The show redundancy linecard all command output displays the Cisco uBR 3x10 RF Switch information under the "linecard redundancy detail" section when the Cisco UBR-RFSW-ADV is enabled.

CSCtz63955

The SNMP request used by the CMTS to discover the Cisco uBR 3x10 RF Switch uses NULL IP address when the Cisco UBR-RFSW-ADV is disabled and the IP address of the Cisco uBR 3x10 RF Switch is not configured.

CSCua01780

The debug command output displays incorrect slot information after switchover when the Cisco UBR-RFSW-ADV and debug hccp rfswitch are enabled.

CSCua07176

The show hccp channel-switch state command output displays incorrect information for the Cisco UBR-MC3GX60V line card downstream when the Cisco UBR-RFSW-ADV is enabled.

CSCub43523

Switchover fails during the Cisco UBR-RFSW-ADV image upgrade. This issue occurs when switchover is attempted while the Cisco UBR-RFSW-ADV image is being upgraded. The cable rfswitch set-active switch-image command downloads the new image to the switch card and it takes approximately three minutes to upgrade the image on one switch card and about an hour on all 24 switch cards. Wait until the upgrade is fully complete before attempting a switchover.

CSCtz45658

The Cisco CMTS stops communicating with the Cisco UBR-RFSW-ADV when the standby PRE, which was not connected before PRE switchover, becomes active.

Resolved Caveats

There are no resolved caveats.
