Hi there,

Depending on the model of switch you're using, the encapsulation may be required for the trunk port.


interface fa0/2

switchport trunk encapsulation dot1q

switchport mode trunk

Also, you should check to ensure that your VLAN 2 SVI is working and not shutdown. (switches default to vlan1).

Have you created the actual VLAN on the switch?

you should also check to ensure you have the default gateway on the switch.

good luck!

On the switch if you do a "show vlan" does vlan 2 and 6 show active ? If not you have not created the layer 2 vlan on the switch side . The rest of the config looks ok .
