Module: DOCS-IF31-MIB

OID (symbolic): DOCS-IF31-MIB::docsIf31CmUsOfdmaChanChannelId

OID (numeric): 1.3.6.1.4.1.4491.2.1.28.1.13.1.12

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

What is docsIf31CmUsOfdmaChanChannelId?

The cable modem's own identification number (0-255) for this OFDMA upstream channel on its MAC interface; if the interface is down the modem reports its last known value, and an unknown channel ID reads as 0. Admins use this to match the modem's self-reported channel view against the corresponding CMTS-side channel table entry.
