stnExtSubnetL3SubnetIfInstance
Module: STN-EXTIF-MIB
OID (symbolic): STN-EXTIF-MIB::stnExtSubnetL3SubnetIfInstance
OID (numeric): 1.3.6.1.4.1.3551.3.1.1.4.1.1
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The subnet interface instance associated with the L3 interface.
What is stnExtSubnetL3SubnetIfInstance?
This read-only Integer32 gives the subnet interface instance number and serves as the index into the stnExtSubnetL3Table, which is keyed directly by subnet instance rather than by interface name or IP address. An admin uses this table to look up a Layer 3 interface's full details starting from a known subnet instance number. For example, querying subnet instance 2 as the index returns that same instance number confirming the row, alongside its interface name and addressing in other columns.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.4.1.1 snmpwalk -v2c -c public <target> STN-EXTIF-MIB::stnExtSubnetL3SubnetIfInstance
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.3551.3.1.1.4.1.1.1 snmpget -v2c -c public <target> STN-EXTIF-MIB::stnExtSubnetL3SubnetIfInstance.1
