switch between multiple VLANs

Unanswered Question
Apr 6th, 2009


I have multiple VLANs available on my network and I have a user who wants to switch between multiple VLANs (i.e. VLAN2,VLAN3 and Vlan4) on his PC. He has the correct drivers/software that will allow him to add VLANs to his NIC but I want to set his port correctly so that he is able to move between spacified VLANs when he needs to do so...

Setup is Cisco 3750-E,Cisco 2950 VLAN 802.1q, PC setup is Windows XP pro with Intel PRO 100+ NIC.

Any things for me to consider on how to make sure he is set up properly to allow my user to do this?

Thanks in advance to those who reply.

I have this problem too.

It sounds like the server is able to use 802.2q trunking and so all you need to do is set

interface fax/x


switchport trunk encapsulation dot1q

switchport mode trunk

This will allow all vlans to be trunked with the native vlan set to be vlan 1. This is OK to use if Vlan 1 isn't being used on your network?

However I would limit the Vlans your user is allowed to trunk to with the following

interface fax/x

switchport trunk allowed vlan 2-4
