Cisco Building Broadband Service Manager (BBSM) Version 5.1 servers
BBSM v5.1 servers connecting to Cisco 2950/3550 class switches shipped with IOS load 12.1x
Clients cannot access BBSM v5.1 servers.
New Cisco 2950/3550 class switches shipped with IOS load 12.1(9) contain a bug, which was patched by using BBSM Patch 1066. This patch and Cisco IOS® software combination has proven to be an ineffective solution in the long-term.
Clients cannot access BBSM v5.1 servers, or experience dramatic server performance degregation.
Customers will need to load BBSM patch 1067 and the new IOS version. Customers will need to install the new IOS on all affected 2950/3550 switches, in addition to installing the patch on all BBSM servers connected to these switches.
The BBSM patch can be provided to you directly, and will be loaded on CCO immediately. The BBSM patch must be installed in conjunction with the new Cisco IOS software image.
To follow the links below to download software, you must be a registered user, and you must be logged in.

The Cisco IOS software image must be installed in conjunction with the new BBSM patch, and is available from the Software Download Center on CCO.

Note: Catalyst 2950 switches running Cisco IOS Software Release 12.0.x are not affected by this and should not be upgraded. For these switches, after installing Patch 1067 on the BBSM server, change the switch type to Cisco 2950 - xx (12.0), where xx is the number of ports (12, 24 or 48).
