Release Notes for Cisco uBR924 Cable Access Router for Cisco IOS Release 12.1(5)T
OL-0385-04 Rev. B0 (2/2001)
Important Notes
• SNMP standard MIBs—These are the MIBs required by any agent supporting SNMPv1 or
SNMPv2 network management.
• Cable-specific MIBs—These MIBs provide information about the cable interface and related
information on the Cisco uBR924 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 uBR924 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been replaced by more standardized, scalable MIBs.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.
Cable Device MIBs
The Cisco uBR924 Cable Access Router supports the Cable Device MIB, which is defined by RFC 2669
and describes DOCSIS-compliant cable modems and CMTS. The Cable Device MIB records statistics
related to the configuration and status of the cable modem. Statistics include an events log and device
status. The following list details the components of the Cable Device MIB:
• “docsDevBase” group extends the MIB-II “system” group with objects needed for cable device
system management.
• “docsDevNmAccess” group provides a minimum level of SNMP access security.
• “docsDevSoftware” group provides information for network downloadable software upgrades.
• “docsDevServe” group provides information about the progress of interaction with various
provisioning servers.
• “docsDevEven” group provides information about the progress of reporting.
• “docsDevFilter” group configures filters at link layer and IP layer for bridge data traffic.
The Cable Device MIB is very similar to the RFI MIB in that both allow access to statistics; they are
different in that the Cable Device MIB reports statistics on the cable modem, and the RFI MIB reports
statistics on the radio frequency transmissions over the cable television line.
Cisco Standard MIBs
The Cisco uBR924 Cable Access Router supports the Cisco Standard MIBs, which consist of the
following components:
• CISCO-PRODUCT-MIB
• CISCO-SYSLOG-MIB
• CISCO-FLASH-MIB
