Module: DOT3-OAM-MIB

OID (symbolic): DOT3-OAM-MIB::dot3OamUnsupportedCodesRx

OID (numeric): 1.3.6.1.2.1.158.1.4.1.16

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

Discontinuities of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of the ifCounterDiscontinuityTime.

What is dot3OamUnsupportedCodesRx?

This read-only counter counts OAMPDUs received on this interface with an op-code the local device doesn't support. An admin seeing this climb should suspect the peer is running a newer or vendor-extended OAM feature set that this device can't interpret.
