ipNetToMediaIfIndex
Module: CHECKPOINT-MIB-2
OID (symbolic): CHECKPOINT-MIB-2::ipNetToMediaIfIndex
OID (numeric): 1.3.6.1.2.1.4.22.1.1
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 ipNetToMediaIfIndex?
Identifies, via the same index scheme as ifIndex, which interface this ARP-table entry belongs to. This is the join key an admin uses to figure out on which specific interface a particular IP-to-MAC mapping was learned, important on a multi-interface gateway where the same IP could theoretically appear via more than one path. Example: ipNetToMediaIfIndex value 2 on an entry for a suspicious IP confirms that mapping was learned on the DMZ interface, not the internal one, narrowing where to investigate.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.4.22.1.1 snmpwalk -v2c -c public <target> CHECKPOINT-MIB-2::ipNetToMediaIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.4.22.1.1.1 snmpget -v2c -c public <target> CHECKPOINT-MIB-2::ipNetToMediaIfIndex.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.4.22.1.1.1 i <value>
