mplsLdpSessionRole

Module: MPLS-LDP-STD-MIB

OID (symbolic): MPLS-LDP-STD-MIB::mplsLdpSessionRole

OID (numeric): 1.3.6.1.2.1.10.166.4.1.3.3.1.3

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: During session establishment the LSR/LER takes either the active role or the passive role based on address comparisons. This object indicates whether this LSR/LER was behaving in an active role or passive role during this session's establishment.

The value of unknown(1), indicates that the role is not able to be determined at the present time.

What is mplsLdpSessionRole?

This OID reports whether this LSR acted in the active or passive role during this session's establishment (determined by address comparison per RFC 3036 section 2.5.3), or unknown if not yet determinable. Admins use this to understand which side initiated the TCP connection for a given LDP session.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.166.4.1.3.3.1.3
snmpwalk -v2c -c public <target> MPLS-LDP-STD-MIB::mplsLdpSessionRole

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.166.4.1.3.3.1.3.1
snmpget -v2c -c public <target> MPLS-LDP-STD-MIB::mplsLdpSessionRole.1
