What is arp2EntryAge?
This OID tracks the age (in seconds) of an ARP cache entry in a secondary ARP table. Engineers check this to verify that recently learned IP-to-MAC mappings are still fresh and valid. A value of 300 indicates the ARP entry is 5 minutes old.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.2.1.5 snmpwalk -v2c -c public <target> ACMIB::arp2EntryAge
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.2.1.5.1 snmpget -v2c -c public <target> ACMIB::arp2EntryAge.1
