What is mplsLdpSessionState?

This OID reports this LDP session's current state in the RFC 3036 session-negotiation state machine: nonexistent, initialized, openrec, opensent, or operational. Admins check this first when troubleshooting an LDP peering that won't come up, to see exactly where in the negotiation sequence it's stuck.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.166.4.1.3.3.1.2
snmpwalk -v2c -c public <target> MPLS-LDP-STD-MIB::mplsLdpSessionState

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.166.4.1.3.3.1.2.1
snmpget -v2c -c public <target> MPLS-LDP-STD-MIB::mplsLdpSessionState.1
