bridgeDomainForwardDelay
Module: ACMIB
OID (symbolic): ACMIB::bridgeDomainForwardDelay
OID (numeric): 1.3.6.1.4.1.1751.2.18.5.9.1.12
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This time value, measured in units of hundredths of a second, controls how fast a port changes its state. The value determines how long the port stays in each of the Listening and Learning states, which precede the Forwarding state. This value is also used, when a topology change has been detected and is underway, to age all dynamic entries in the Forwarding Database. [Note that this value is the one that this bridge is currently using, in contrast to bridgeDomainBridgeForwardDelay which is the value that this bridge and all others would start using if/when this bridge were to become the root.]
What is bridgeDomainForwardDelay?
This OID controls how long (in hundredths of seconds) a port remains in the Listening and Learning states before transitioning to Forwarding and actively relaying traffic. Engineers adjust this to balance convergence speed against the risk of creating temporary forwarding loops during topology changes. A value of 1500 (15 seconds) means ports wait up to 15 seconds in intermediate states before becoming active.
