16- and 36-Port Ethernet Switch Module for Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Configuration Examples for the 16- and 36-Port Ethernet Switch Module 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# Cisco IOS Release 12.2(2)XT, 12.2(8)T, and 12.2(15)ZJ 137
