Router#

The following example shows how to configure the switch as VTP transparent:

Router#configure terminal

Router(config)#vtp transparent

Setting device to VTP TRANSPARENT mode.

Router(config)#exit

APPLY completed.

Exiting....

• Spanning-Tree Port Cost: Example, page 82

• Bridge Priority of a VLAN: Example, page 82

• Hello Time: Example, page 82

• Forward-Delay Time for a VLAN: Example, page 83

Spanning-Tree Interface and Spanning-Tree Port Priority: Example

The following example shows the VLAN port priority of an interface being configured:

Router#configure terminal

Router(config)#interface gigabitethernet 0/1/2

Router(config-if)#spanning-tree vlan 1 port-priority 64

Router(config-if)#end

Router#

The following example shows how to verify the configuration of VLAN 1 on the interface when it is

configured as a trunk port:

Router#show spanning-tree vlan 1

VLAN1 is executing the ieee compatible Spanning Tree protocol

Bridge Identifier has priority 32768, address 0025.451b.b22a

Configured hello time 2, max age 20, forward delay 15

Current root has priority 32768, address 0008.e36d.9f70

Root port is 18 (GigabitEthernet0/1/4), cost of root path is 38

Topology change flag not set, detected flag not set

Number of topology changes 18 last change occurred 22:36:19 ago

from GigabitEthernet0/1/2

Times: hold 1, topology change 35, notification 2

hello 2, max age 20, forward delay 15

Timers: hello 0, topology change 0, notification 0, aging 300

Port 18 (GigabitEthernet0/1/2) of VLAN1 is forwarding

Port path cost 19, Port priority 128, Port Identifier 128.18.

Designated root has priority 32768, address 0008.e36d.9f70

Designated bridge has priority 32768, address 0022.bdc5.2233

Designated port id is 128.35, designated path cost 19
