Configuration description
VLAN2
Site A and site B switch port 2 -4.
VLAN100
Site A and site B switch port 5 -7.
VLAN200
Site A and site B switch port 8 -10.
Trunk port
Site A and site B switch port 11.
Connect the Trunk ports of both switches for a Trunk link to convey the cross-switch
VLAN traffic; connect all network devices to the other ports of corresponding VLANs.
In this example, port 1 and port 12 is spared and can be used for management port or for
other purposes.
The configuration steps are listed below:
Switch A:
Switch(Config)#vlan 2
Switch(Config-Vlan2)#switchport interface ethernet 0/0/2-4
Switch(Config-Vlan2)#exit
Switch(Config)#vlan 100
Switch(Config-Vlan100)#switchport interface ethernet 0/0/5-7
Switch(Config-Vlan100)#exit
Switch(Config)#vlan 200
Switch(Config-Vlan200)#switchport interface ethernet 0/0/8-10
Switch(Config-Vlan200)#exit
Switch(Config)#interface ethernet 0/0/11
Switch(Config-Ethernet0/0/11)#switchport mode trunk
Switch(Config-Ethernet0/0/11)#exit
Switch(Config)#
Switch B:
Switch(Config)#vlan 2
Switch(Config-Vlan2)#switchport interface ethernet 0/0/2-4
Switch(Config-Vlan2)#exit
Switch(Config)#vlan 100
Switch(Config-Vlan100)#switchport interface ethernet 0/0/5-7
Switch(Config-Vlan100)#exit
Switch(Config)#vlan 200
Switch(Config-Vlan200)#switchport interface ethernet 0/0/8-10
Switch(Config-Vlan200)#exit
Switch(Config)#interface ethernet 0/0/11
