we have some issues with the UC550 connecting itself to an accesspoint via CCA from a router. The connection works fine and calls can be made, it's just the connection for while administering the UC540.

Setup (only relevant parts):

--- wan --- router if1 | [] | --- UC500 fe1

                   if2 | []     | --- UC500 fe2

In words: two interfaces of our router which have each an IP of UC's subnets, are connected to tweo interfaces of the UC.

I can ping the UC ( and, I can connect to it from the laptop/router and I can ping devices within those subnets from the UC but not from my laptop or router.

Also, when I connect via CCA to the UC it finds the Accesspoint ( but it can't connect itself to it, so I can't add it to the site for example.

I can't get it to work, could anyone please help me with this?

Hi Michal,

English is not your first language. That is ok, I am too dumb to be able to speak another language 

I am having trouble understanding your problem description and your network setup..

Would it be possible to put together a better network diagram.  Even use Windows paint, it is better than no diagram at all.

regards David

Hi David,

thank you for your prompt feedback and I apologize both for my late reply and for my hardly understandable description of our problem. It was really, really late after a few very long shifts we had to do.

I attached a better network diagram to this post and I hope you can now understand our setup.

The problem we now have is as follows:

We try to access our UC500 and it's subnets / VLANS from the SBS2003.

What works:

We can access the UC540 by HTTPS on and When we connect to the UC540 with CCA it is found and can be edited. The UC also discovers the accesspoints ( and .202) and displays them in the neighborhood but here the problem starts:

The UC doesn't seem to be able to connect to those AP. When scanning the site the AP are discovered and I am asked for the credentials to the AP but then they marked with a red cross and it says "IOS command not found".

When I then connect to the UC the AP is displayed as "in the neighborhood" but when I try to add it to the site i get an error message stating "Output of /exec/show/ver/CR not found".

So what are we doing wrong?
