Configuring the Forward-Delay Time for a VLAN

Exercise care when configuring forward-delay time. In most cases, we recommend that you use the
Note
spanning-tree vlan vlan_ID root primary and the spanning-tree vlan vlan_ID root secondary
commands to modify the forward delay time.
To configure the spanning tree forward delay time for a VLAN, perform this task:
Command
Step 1
Switch(config)# [no] spanning-tree vlan vlan_ID
forward-time forward_time
Step 2
Switch(config)# end
Step 3
Switch# show spanning-tree vlan vlan_ID bridge
[brief]
This example shows how to configure the forward delay time for VLAN 200 to 21 seconds:
Switch# configure terminal
Switch(config)# spanning-tree vlan 200 forward-time 21
Switch(config)# end
Switch#
