Description: Specifies the instance index of the primary instance of this tunnel.

What is mplsTunnelPrimaryInstance?

This read-only object specifies the instance index of the primary tunnel instance associated with an MPLS traffic-engineering tunnel. An operator uses this to identify which tunnel instance is the main path when multiple instances exist for redundancy.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.3.95.2.2.1.21
snmpwalk -v2c -c public <target> MPLS-TE-MIB::mplsTunnelPrimaryInstance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.3.95.2.2.1.21.1
snmpget -v2c -c public <target> MPLS-TE-MIB::mplsTunnelPrimaryInstance.1
