16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series
The following example shows how to verify the configuration of the interface when it is configured as
an access port:
Router# show spanning-tree interface fastethernet 5/8
Port 264 (FastEthernet5/8) of VLAN200 is forwarding
Port path cost 18, Port priority 100, Port Identifier 129.8.
Designated root has priority 32768, address 0010.0d40.34c7
Designated bridge has priority 32768, address 0010.0d40.34c7
Designated port id is 128.1, designated path cost 0
Timers: message age 2, forward delay 0, hold 0
Number of transitions to forwarding state: 1
BPDU: sent 0, received 13513
Router#
The following example shows how to configure the spanning-tree VLAN port cost of a Fast Ethernet
interface:
Router# configure terminal
Router(config)# interface fastethernet 5/8
Router(config-if)# spanning-tree vlan 200 cost 17
Router(config-if)# exit
Router(config)# exit
Router#
Bridge Priority of a VLAN
The following example shows the bridge priority of VLAN 200 being configured to 33792:
Router# configure terminal
Router(config)# spanning-tree vlan 200 priority 33792
Router(config)# end
Router#
Hello Time Example
The following example shows the hello time for VLAN 200 being configured to 7 seconds:
Router# configure terminal
Router(config)# spanning-tree vlan 200 hello-time 7
Router(config)# end
Router#
Forward-Delay Time for a VLAN Example
The following example shows the forward delay time for VLAN 200 being configured to 21 seconds:
Router# configure terminal
Router(config)# spanning-tree vlan 200 forward-time 21
Router(config)# end
Router#
Maximum Aging Time for a VLAN Example
The following example configures the maximum aging time for VLAN 200 to 36 seconds:
Router# configure terminal
Router(config)# spanning-tree vlan 200 max-age 36
Router(config)# end
Router#
