Description
The SET SPANTREE FORWARD_DELAY_TIME command enables you to set
the amount of time the bridge waits in each of the states when moving
from Listening to Forwarding mode. This command setting takes effect
only if this bridge becomes the Root Bridge. The modes that are affected
by this parameter are Listening and Learning.
For example, using the default time of 15 seconds, a backup bridge (in a
Blocking state) requires a total of 30 seconds to take over as the
designated bridge once it has determined that the primary (or designated)
bridge has failed: 15 seconds in the Listening state, 15 seconds in the
Learning state, and then the Forwarding of packets starts again.
