stpInfoForwardDelay 1.3.6.1.4.1.11.2.3.7.11.33.4.2.2.3.3.1.1.11

This time value, measured in units of hundredths of a second, controls how fast a port changes its spanning state when moving towards the Forwarding 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.
