cpwVcInboundVcLabel
Module: CISCO-IETF-PW-MIB
OID (symbolic): CISCO-IETF-PW-MIB::cpwVcInboundVcLabel
OID (numeric): 1.3.6.1.4.1.9.10.106.1.2.1.20
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-create
Description: The VC label used in the inbound direction (i.e. packets received from the PSN. It may be set up manually if owner is 'manual' or automatically otherwise. Examples: For MPLS PSN, it represents the 20 bits of VC tag, for L2TP it represent the 32 bits Session ID. If the label is not yet known (signaling in process), the object should return a value of 0xFFFF.
What is cpwVcInboundVcLabel?
This is the label or session ID this device expects on packets arriving from the PSN for this specific pseudowire, letting it demultiplex incoming MPLS or L2TPv3 traffic to the right VC. Inbound and outbound labels are typically assigned independently by each end, so comparing this to what the peer reports as its outbound label confirms the label mapping is consistent end to end. If the peer's outbound label doesn't match what's configured here as inbound, traffic for the VC will arrive with an unrecognized label and be discarded.
