Configuring a Switch for VLAN Tagging and Trunking

1. Log on to the switch.
2. Enter enable to access Privileged EXEC mode.
3. Create one or more VLANs in the VLAN database.

   For example:

   (Extreme 220) #vlan database
   (Extreme 220) (Vlan)#vlan 10,20,30
   (Extreme 220) (Vlan)#exit

4. Enter Global Config mode and enable trunk mode on the interface.

   For example:

   (Extreme 220) #configure
   (Extreme 220) (Config) #interface 1/0/2
   (Extreme 220) (Interface 1/0/2) #vlan tagging 10,20,30
   (Extreme 220) (Interface 1/0/2) #vlan participation include 10,20,30
   (Extreme 220) (Interface 1/0/2) #exit
   (Extreme 220) (Config) #exit

   

   Note

   Optionally, you can also configure VLANs tagging by using the trunk mode option, which works in the same way as the previous example:

   (Extreme 220) #config
   (Extreme 220) (Config) #interface 1/0/2
   (Extreme 220) (Interface 1/0/2) #switchport mode trunk
   (Extreme 220) (Interface 1/0/2) #switchport trunk allowed vlan 10
   (Extreme 220) (Interface 1/0/2) #switchport trunk allowed vlan add 20.30
   (Extreme 220) (Interface 1/0/2) #exit
   (Extreme 220) (Config) #exit
   (Extreme 220) #write memory confirm

5. Save your configuration.
