pwMplsTtl
Module: PW-MPLS-STD-MIB
OID (symbolic): PW-MPLS-STD-MIB::pwMplsTtl
OID (numeric): 1.3.6.1.2.1.181.1.1.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: This object is set by the operator to indicate the PW TTL value to be used on the PW shim label.
What is pwMplsTtl?
This value, from 0 to 255, is the TTL to use on the pseudowire's MPLS shim label, set by the operator, defaulting to 2. Admins adjust it to control how many hops the PW label itself would survive if it were exposed, which affects diagnostic traceability and traceroute-style behavior. Leaving pwMplsTtl at its default value of 2 matches the standard convention for a PW label that typically isn't meant to be traced hop by hop.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.181.1.1.1.4 snmpwalk -v2c -c public <target> PW-MPLS-STD-MIB::pwMplsTtl
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.181.1.1.1.4.1 snmpget -v2c -c public <target> PW-MPLS-STD-MIB::pwMplsTtl.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.181.1.1.1.4.1 i <value>
