Module: DOCS-IF31-MIB

OID (symbolic): DOCS-IF31-MIB::docsIf31CmtsDsOfdmChanChannelId

Description: The Cable Modem Termination System identification of the OFDM downstream channel within this particular MAC interface. if the interface is down, the object returns the most current value. If the downstream channel ID is unknown, this object returns a value of 0.

What is docsIf31CmtsDsOfdmChanChannelId?

The CMTS's own identification number (0-255) for this OFDM downstream channel on its MAC interface; if the interface is down the CMTS reports its last known value, and an unknown channel ID reads as 0. This is the CMTS-side counterpart to docsIf31CmDsOfdmChanChannelId, which admins use to match the CMTS's channel table entry against a given modem's self-reported channel ID.
