Question

VLANs, Cisco 2950 and Aironet 350?

Asked by: j2

Ok, now a routing question oer se. But here goes

I have 3 sites, each with a Cisco 2950 and an Aironet 350 in bridge mode.

Now, no matter how i try, i can not get VLAN's to work across the radio bridges. I have tried quite a few things, but just cant get it to work.

Each site has 2 to 4 VLAN's, and the port connected to the Aironet is in "Trunk Desirable" mode.

G'day j2,

I don't think you can bridge a trunk port with a wireless bridge. It is not designed for that.


Cheers!

Well, someone said that on older Aironets, all you had to do was to enlarge the framesize? And the aironet itself has VLAN support, i just figure it must be doable somehow?

 

by: lrmoorePosted on 2003-06-09 at 11:34:45ID: 8684307

What version code on the Aironet?

 

by: lrmoorePosted on 2003-06-09 at 11:39:39ID: 8684348

Actually, reduce the frame size on everything else:

"The following caveats have not been resolved for firmware version 12.01T1:

CSCdz04708—Early 340 series access points are incompatible with VLAN tagging. "


Look in the Open Caveat section (just search on VLAN)

Is "Cisco 350 Series Bridge 12.00T" sufficient for you to tell?

 

by: lrmoorePosted on 2003-06-09 at 11:48:45ID: 8684436

So, If I read you right, Look at Figure 4 in this document and tell me if that is what you are trying to accomplish, minus the 3d bridge:

_Exactly_ that even  (i do have 3 sites, but i do not _need_ VLAN to one site _yet_ But i prolly will shortly).

 

by: j2Posted on 2003-06-09 at 21:21:46ID: 8687785

Have you ever worked with a setup like this? Ill do some testing lateron today, the points will be yours as soon as i have tried it out, even tho it isnt really a "turn key" answer, it sure as heck shows that it is indeed possible. Thanks.

 

by: j2Posted on 2003-06-12 at 12:42:15ID: 8712004

It was _nightmarish_ to get it working (ended up getting a certified Cisco consultant to do it after i failed.. He failed as well for quite a few hours) but now it works. And you get the point, since you gave me the link to the document showing me that it was indeed possible.
