Example 161 Configuring Gigabit Ether Channel with 8021Q Encapsulation

walker1(config)#interface gigabit 0/2

walker1(config-if)#switchport trunk encapsulation dot1q walker1(config-if)#switchport mode trunk walker1(config-if)#exit walker1(config)#interface fast 0/17

walker1(config-if)#switchport trunk encapsulation dot1q walker1(config-if)#switchport mode trunk walker1(config-if)#exit

At this point of the configuration, VTP should be working between switches, and you should be able ping all local devices. Use the show vtp status command to verify VTP and ensure that both switc have the same VTP revision number and the same number of VLANs.

The next portion of the configuration requires you to enable 802.1s and 802.1w spanning tree. RST is partially enabled at this point from using the spanning-tree portfast command on all nontrunk interfaces. RSTP will be fully enabled when 802.1s or MST is enabled. The MST configuration on the walkerl and walker2 switches will be identical, except that the walkerl switch will use the spannii tree mst 1 root primary command to set root for VLANs 2 through 300. You will define a single S instance, MST 1, and assign VLANs 2 through 300 to this instance. The MST name will be walker, a the revisi on will be 1.
