Using the CLI to Configure VLANs

1. Create VLAN 2 and VLAN 3.

   (Extreme 220) (Routing) #vlan database
   vlan 2
   vlan 3
   exit

2. Assign ports 1/0/1 and 1/0/2 to VLAN2 and specify that untagged frames will be rejected on receipt.

   (Extreme 220) (Routing) #Config
   interface1/0/1
   vlan participation include 2
   vlan acceptframe vlanonly
   exit
   interface1/0/2
   vlan participation include 2
   vlan acceptframe vlanonly

3. While in interface config mode for port 1/0/2, assign VLAN3 as the default VLAN.

   (Extreme 220) (Routing) (Interface 1/0/2)#vlan pvid 3
   exit

4. Specify that frames will always be transmitted tagged from ports that are members of VLAN 2.

   (Extreme 220) (Routing)(Config)#vlan port tagging all 2
   exit

5. Assign the ports that will belong to VLAN 3.

   Port 1/0/2 belongs to both VLANs, and port 1/0/1 can never belong to VLAN 3.

   (Extreme 220) (Routing) #Config
   interface1/0/2
   vlan participation include 3
   exit
   interface1/0/3
   vlan participation include 3
   exit
   interface1/0/4
   vlan participation include 3
   exit
   exit

6. Specify that untagged frames will be accepted on port 1/0/4.

   (Extreme 220) (Routing) #Config
   interface1/0/4
   vlan acceptframe all
   exit
   exit
