Cable Device MIB
The Cable Device MIB is for DOCSIS-compliant cable modems and Cable Modem Termination
Systems (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.
• docsDevServer group provides information about the progress of interaction with various
provisioning servers.
• docsDevEvent 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.
