ieee8021QBridgeFdbAgingTime
Module: IEEE8021-Q-BRIDGE-MIB
OID (symbolic): IEEE8021-Q-BRIDGE-MIB::ieee8021QBridgeFdbAgingTime
OID (numeric): 1.3.111.2.802.1.1.4.1.2.1.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The timeout period in seconds for aging out dynamically-learned forwarding information. IEEE Std 802.1D-1998 recommends a default of 300 seconds.
The value of this object MUST be retained across reinitializations of the management system.
What is ieee8021QBridgeFdbAgingTime?
How many seconds (10 to 1,000,000) a dynamically learned MAC address stays in the forwarding database before aging out; IEEE 802.1D recommends a default of 300 seconds, and lowering it makes the switch adapt faster to moved devices at the cost of more relearning.
Examples
