Configuring The Hello Time; Configuring The Forward-Delay Time For A Vlan - Cisco 6500 Series Software Configuration Manual

Configuring STP

Configuring the Hello Time

Be careful when using this command. For most situations, we recommend that you use the
Note
spanning-tree vlan vlan_ID root primary and spanning-tree vlan vlan_ID root secondary commands
to modify the hello time.
To configure the STP hello time of a VLAN, perform this task:
Command
Step 1
Router(config)# spanning-tree vlan vlan_ID
hello-time hello_time
Router(config)# no spanning-tree vlan vlan_ID
hello-time
Step 2
Router(config)# end
Step 3
Router# show spanning-tree vlan vlan_ID bridge
[detail]
This example shows how to configure the hello time for VLAN 200 to 7 seconds:
Router# configure terminal
Router(config)# spanning-tree vlan 200 hello-time 7
Router(config)# end
Router#
This example shows how to verify the configuration:
Router# show spanning-tree vlan 200 bridge

Configuring the Forward-Delay Time for a VLAN

To configure the STP forward delay time for a VLAN, perform this task:
Command
Step 1
Router(config)# spanning-tree vlan vlan_ID
forward-time forward_time
Router(config)# no spanning-tree vlan vlan_ID
forward-time
Step 2
Router(config)# end
Step 3
Router# show spanning-tree vlan vlan_ID bridge
