Module: MELLANOX-DCB-TRAPS-MIB
OID (symbolic): MELLANOX-DCB-TRAPS-MIB::mellanoxDCBPortPFCOperState
OID (numeric): 1.3.6.1.4.1.33049.8.1.1.3.1.5
Node type: OBJECT-TYPE
Type: ProtocolStateType
Access: read-only
Description: PFC operational state on port
What is mellanoxDCBPortPFCOperState?
This read-only ProtocolStateType, indexed by ifIndex in the mellanoxDCBPortTable, reports the actual operational PFC state currently in effect on a specific port. Admins check this to confirm PFC is genuinely active and providing lossless pause behavior on that link, since a mismatch with the administrative state signals a DCBX negotiation problem with the peer. For example, a port showing PFC admin state enabled but oper state inactive would explain why RoCE traffic on that link is experiencing unexpected packet drops.
