Disabling Spanning Tree Protocol - Cisco 4500M Software Manual

Chapter 14 Understanding and Configuring STP
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#
This example shows how to verify the configuration:
Switch# show spanning-tree vlan 200 bridge brief
