What is bridgeCacheEntryAge?
This OID records how long (in seconds) a bridge forwarding table entry has been idle without seeing traffic from that MAC address. Engineers use this to identify stale entries and understand the dynamic behavior of the bridging table. A value of 600 means the MAC address was last seen 10 minutes ago.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.3.1.6 snmpwalk -v2c -c public <target> ACMIB::bridgeCacheEntryAge
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.20.3.1.6.1 snmpget -v2c -c public <target> ACMIB::bridgeCacheEntryAge.1
