SUMMARY STEPS
1.
configure terminal
2.
spanning-tree vlan vlan-id forward-time seconds
3.
end
DETAILED STEPS
PurposeCommand or Action
Enters the global configuration mode.configure terminal

Step 1
Configures the forward time of a VLAN. The forwarding delay is the
number of seconds an interface waits before changing from its
spanning-tree learning and listening states to the forwarding state.
spanning-tree vlan vlan-id forward-time
seconds
Example:
Switch(config)# spanning-tree vlan
20,25 forward-time 18
