Module: IP-MIB
OID (symbolic): IP-MIB::ipAdEntIfIndex
OID (numeric): 1.3.6.1.2.1.4.20.1.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The index value which uniquely identifies the interface to which this entry is applicable. The interface identified by a particular value of this index is the same interface as identified by the same value of the IF-MIB's ifIndex.
What is ipAdEntIfIndex?
This read-only value provides the interface index (ifIndex) associated with an IPv4 address entry in the address table. It acts as a foreign key linking IP address configuration to the physical or logical network interface. Network administrators use this to correlate IP addresses with their corresponding ports and determine which interface carries a given IP.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.4.20.1.2 snmpwalk -v2c -c public <target> IP-MIB::ipAdEntIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.4.20.1.2.1 snmpget -v2c -c public <target> IP-MIB::ipAdEntIfIndex.1
