Re: assigning vlan based on NAS and LDAP field?



Jerry,
I hate to be a pain but what you have implemented atm is my next task
with freeradius.

Would you mind linking any howtos you use, thanks.

Also how do u get freeradius to find a users group then report it back
to the cisco / ap so it can decide what vlan the client belongs on.

Many thanks in advance.

 2. This follows into our future wired side implementation of 802.1x. In

you have to find an attribute in the radius nas request that will
différenciate a wifi connection and a wired 802.1x connection:

for me it is

NAS-Port-Type = Wireless-802.11 for  wifi

and

NAS-Port-Type = ethernet for wired 802.1x

depending on this you send a vlan or an other in the radius response.

but you still can do it depending on the nas IP
