What is stnExtSubnetL3IfIndex?

This read-only InterfaceIndex gives the numeric ifIndex of the Layer 3 interface associated with a given subnet interface instance in the stnExtSubnetL3Table. An admin uses it to resolve a subnet instance number directly to the interface's standard ifIndex. For example, subnet instance 2 might resolve to ifIndex 4001.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.4.1.2
snmpwalk -v2c -c public <target> STN-EXTIF-MIB::stnExtSubnetL3IfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.4.1.2.1
snmpget -v2c -c public <target> STN-EXTIF-MIB::stnExtSubnetL3IfIndex.1
