SET SPANTREE FORWARD_DELAY_TIME
Use the SET SPANTREE FORWARD_DELAY_TIME command to set the amount of time bridges wait in each of the states when moving from Listening to Forwarding mode.
This value will take effect for the overall network when this bridge becomes the Root Bridge.
Format
SET SPANTREE FORWARD_DELAY_TIME {variable}
Parameters
{variable} = 4 - 30 seconds (default is 15 seconds)
See Note for range restrictions.
Example
OEBM> set spantree forward_delay_time 27 [ENTER]

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.
