ifExtnsIfIndex
Module: RFC1229-MIB
OID (symbolic): RFC1229-MIB::ifExtnsIfIndex
OID (numeric): 1.3.6.1.2.1.12.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The value of this object identifies the interface for which this entry contains extended management information. The value of this object for a particular interface has the same value as the ifIndex object, defined in [4,6], for the same interface.
What is ifExtnsIfIndex?
This integer identifies the interface that the row of extended interface information in this table describes. It matches the value of the standard MIB-II ifIndex for the same interface, letting a manager correlate extension data such as chip set, firmware revision, and promiscuous mode with the base interface table. For example, an SNMP walk returning ifExtnsIfIndex 3 means the rest of that row describes interface 3, not any other interface on the device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.12.1.1.1 snmpwalk -v2c -c public <target> RFC1229-MIB::ifExtnsIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.12.1.1.1.1 snmpget -v2c -c public <target> RFC1229-MIB::ifExtnsIfIndex.1
