Release Notes for Cisco uBR7200 Series for Cisco IOS Release 12.1 T
78-10643-04 Rev. B0
Important Notes
The last maintenance release was renamed from 12.1(4)T to 12.1(5)T to synchronize with its parent
software base, the 12.1(5) mainline release, and to reflect that 12.1(5)T has all the bug fixes of the
12.1(5) mainline release. The 12.1 T release train is a superset of the 12.1 mainline release; hence any
defect fixed in the 12.1 mainline is also fixed in 12.1 T. The set of features for 12.1(4)T is the same as
that for 12.1(5)T. There was no change in the feature content of the release. The release was renamed
so that the releases would be consistent with the Cisco release process.
Supported MIBs
The Cisco uBR7200 Series Universal Broadband Routers support the following categories of MIBs:
• SNMP standard MIBs—These are the MIBs that are required by any agent supporting SNMPv1 or
SNMPv2 network management.
• Cisco’s platform and network-layer enterprise MIBs—Common across most of Cisco’s router
platforms. If your network management applications are already configured to support other Cisco
routers, such as the 2600 series or 7200 series, no further configuration is needed unless the version
of Cisco IOS software being used has updated these MIBs.
• Cable-specific and wireless-specific MIBs—Provide information about the cable and wireless
interfaces and related information on the uBR7200 series routers. They include both
DOCSIS-specific MIBs and Cisco-specific enterprise MIBs. If your network management
applications have not already been configured for the uBR7200 series routers, these MIBs must be
loaded.
• Deprecated MIBs—Supported in earlier releases of Cisco IOS software but have been replaced by
more standardized, scalable MIBs. Network Management applications and scripts should convert
to the replacement MIBs as soon as possible.
The cable-specific and wireless-specific MIBs are described in the following sections. For information
on the SNMP standard MIBs and Cisco’s platform and network-layer enterprise MIBs, see Cisco’s MIB
web site at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml.
Cable-Specific and Wireless-Specific MIBs
Table 8 shows the cable-specific and wireless-specific MIBs that are supported on the
Cisco uBR7200 Series Universal Broadband Routers. The table also provides a brief description of
each MIB’s contents and the Cisco IOS Software 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 8 are the filenames for the MIBs as they exist on Cisco’s FTP
site. Most MIBs are available in both SNMPv1 and SNMPv2 versions; the SNMPv1
versions have V1SMI as part of their filenames.
