pwVcMplsTtl
Module: PW-MPLS-DRAFT06-MIB
OID (symbolic): PW-MPLS-DRAFT06-MIB::pwVcMplsTtl
OID (numeric): 1.3.6.1.4.1.99999.53.0.1.1.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Set by the operator to indicate the PW TTL value to be used on the PW shim label.
What is pwVcMplsTtl?
This read-write Unsigned32 (0-255), set by the operator, sets the TTL value placed on the PW's MPLS shim label, defaulting to 2. An admin adjusts this to control how many hops the PW label can traverse before expiring, which matters for traceroute visibility and loop protection in the MPLS core. For example, lowering it from the default 2 to 1 would cause the PW label to expire immediately at the first downstream LSR, which an admin would avoid unless deliberately testing failure behavior.
