Example #3: Assign Ports to VLAN3
This example shows how to assign the ports that will belong to VLAN 3. Untagged frames will be
accepted on ports 1/g19 and 1/g20.
Note that port 1/g18 belongs to both VLANs and that port 1/g17 can never belong to VLAN 3.
console(config)#interface ethernet 1/g18
cconsole(config-if-1/g18)#switchport general allowed vlan add 3
console(config-if-1/g18)#exit
console(config)#interface ethernet 1/g19
console(config-if-1/g19)#switchport general allowed vlan add 3
console(config-if-1/g19)#exit
console(config)#interface ethernet 1/g20
console(config-if-1/g20)#switchport general allowed vlan add 3
Example #4: Assign VLAN3 as the Default VLAN
This example shows how to assign VLAN 3 as the default VLAN for port 1/g18.
console(config)#interface ethernet 1/g18
console(config-if-1/g18)#switchport general pvid 3
Example #5: Assign IP Addresses to VLAN 2
In order for the VLAN to function as a routing interface, you must enable routing on the VLAN and on
the switch. Routing is only permitted on VLAN interfaces. Routing on physical interfaces is not
supported.
console#configure
console(config)#interface vlan 2
console(config-if-vlan2)#ip address 192.168.10.33 255.255.255.0
console(config-if-vlan2)#routing
console(config-if-vlan2)#exit
console(config)#ip routing
