20 Release Notes for Cisco uBR904 Cable Access Router for Cisco IOS Release 12.0(7)T
Important Notes
• Cable-specific MIBs—These MIBs provide information about the cable interface and related
information on the Cisco uBR904 cable access router. They include both DOCSIS-required
MIBs and Cisco-specific enterprise MIBs. If your network management applications have not
already been configured for the Cisco uBR904 cable access router, these MIBs must be loaded.
• Deprecated MIBs—These MIBs were 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have been replaced by more standardized, scalable MIBs.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 MIBs and Deprecated 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 MIBs
Table 5 shows the cable-specific MIBs that are supported on the Cisco uBR904 cable access router.
This 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 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.
