thanks acomiskey,

I setup the work with success

but i have a problem to solve...

The client authenticated, but is nothing getting IP address from dhcp server, because the dhcp server is in another vlan and is another network range . follow settings:

dhcp server and ias server (w2k3):

vlan : 10

ip : / 24

client pc (wxp) (after authenticated)

vlan : 20

ip range : /24

guest vlan : 30

what would i do to get dynamic ip from DHCP ?

does have a dhcp server in same vlan and address range of client pc ?

Att Antonio

i included this instructions, but didn't solve the problem...

what can be occurring ?

follow sh rum command attached on post..

obs :

fe 0/9 - my w2k3 server (ad server + ias server + dhcp server)

fe 0/17 - my client pc wXP

fe 0/10 - is a trunk to a linux server, that it's making routing vlan's using.

Your vlan's appear to be "shutdown".

if i set

int vlan 20

no shut

..........vlan 10 that is my up vlan and that a i use to manager the switch goes down !

and after

int vlan 30

no shut

....vlan 20 goes down...

so, the switch 2950 only permit that i have ONE vlan on up state....

Hmm, you can have multiple vlans active on the switch, but you cannot have multiple vlan interface active at the same time.

Are you routing between vlans and if so where? I've never done this on a layer 2 switch, but what's happening is typical of a layer 2 switch. You can only have 1 vlan int active at a time. Where is the default gateway for vlan 20 and 30? We may need someone else's help here.

Also, what is this linux server you mentioned?

It's a ubuntu linux, loading a package (modeprobe and 8021q) to routing vlan's.
