What is lanIfIndex?
No DESCRIPTION exists in the source, so this reading is inferred from the INTEGER syntax, read-only access, and the object's column position in the learned-address table. It reports the interface number on which the paired MAC address (lanPhyAddr) was learned. An admin uses it to locate which physical port a given host is plugged into, for troubleshooting or cable-tracing.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.86.2.4.1.1.1 snmpwalk -v2c -c public <target> NAT::lanIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.86.2.4.1.1.1.1 snmpget -v2c -c public <target> NAT::lanIfIndex.1
