Configuring STP
This example shows how to configure the bridge priority of VLAN 200 to 33792 when the extended
system ID is disabled:
Router#
configure terminal
Router(config)#
spanning-tree vlan 200 priority 33792
Router(config)#
end
Router#
This example shows how to verify the configuration:
Router#
show spanning-tree vlan 200 bridge
Hello Max Fwd

Router#
Configuring the Hello Time
Note
Be careful when using this command. For most situations, we recommend that you use the
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:
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
Hello Max Fwd
Step 2
Router(config)#
end
Exits configuration mode.
Step 3
Router#
show spanning-tree
vlan
vlan_ID
bridge
