atIfIndex
Module: CHECKPOINT-MIB-2
OID (symbolic): CHECKPOINT-MIB-2::atIfIndex
OID (numeric): 1.3.6.1.2.1.3.1.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The interface on which this entry's equivalence is effective. The interface identified by a particular value of this index is the same interface as identified by the same value of ifIndex.
What is atIfIndex?
Identifies which interface, using the same index scheme as ifIndex, an address-translation table entry applies to. This is the join key that lets an admin correlate a MAC-to-IP mapping in the address translation table back to the specific physical or logical interface it was learned on, useful when tracking down which link an IP appeared on. Example: atIfIndex value 3 on an entry tells you the mapping was learned on interface 3, not the management interface, when chasing down an unexpected ARP entry.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.3.1.1.1 snmpwalk -v2c -c public <target> CHECKPOINT-MIB-2::atIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.3.1.1.1.1 snmpget -v2c -c public <target> CHECKPOINT-MIB-2::atIfIndex.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.3.1.1.1.1 i <value>
