What is nwRouterIfInstance?

This OID repeats the nwRouterInstance value from the router system table to show which routing service is active on this particular port. All ports running the same routing service carry the same value here, letting an admin group interfaces by service.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.2.1.2.1.1.2
snmpwalk -v2c -c public <target> CTRON-ROUTERS-MIB::nwRouterIfInstance

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.52.4.2.2.2.2.1.2.1.1.2.1
snmpget -v2c -c public <target> CTRON-ROUTERS-MIB::nwRouterIfInstance.1
