bridgeDomainAgingTime
Module: ACMIB
OID (symbolic): ACMIB::bridgeDomainAgingTime
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The timeout period in seconds for aging out dynamically learned forwarding information. 802.1D-1990 recommends a default of 300 seconds.
What is bridgeDomainAgingTime?
This OID specifies the timeout period (10 to 1,000,000 seconds) for which dynamically learned MAC addresses remain in the forwarding database before being aged out and forgotten. Engineers adjust this to prevent stale MAC entries from blocking legitimate traffic and to adapt to changes in network topology. The standard 300-second (5-minute) setting balances responsiveness to device moves with memory efficiency.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.16 snmpwalk -v2c -c public <target> ACMIB::bridgeDomainAgingTime
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.5.9.1.16.1 snmpget -v2c -c public <target> ACMIB::bridgeDomainAgingTime.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1751.2.18.5.9.1.16.1 i <value>
