What is stnExtIfL3IfIndex?

This read-only InterfaceIndex gives the numeric ifIndex associated with a given Layer 3 interface name in the stnExtIfL3Table. An admin uses it to tie a routed interface's textual name to the standard ifIndex used by ifTable and other SNMP interface data. For example, interface name 'Vlan10' might resolve to ifIndex 4001 for further standard interface polling.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.2.1.2
snmpwalk -v2c -c public <target> STN-EXTIF-MIB::stnExtIfL3IfIndex

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.2.1.2.1
snmpget -v2c -c public <target> STN-EXTIF-MIB::stnExtIfL3IfIndex.1
