Cisco 877 & SDM

Hi all,

Suddenly I am not able to log on via SDM. I am getting the following error message. Any ideas? I have no problem logging on via SDM express.

"SDM cannot communicate with the router. Please do one of the following.

Check the connections between your workstation and the router.

Make sure that the router IOS image is one of the supported images (refer to DSDM Q &A).

Clear a VTY line if all the VTY lines are in use."

Config is attached!

Any help appreciated!

Thanks,

Br,

Rob

Re: Cisco 877 & SDM

I get this on my 877 evey now and again but just click retry or close SDM and re-connect and alls good - if the worst come to the worst reset the unit and re-config it using SDM but like myself you'll need to learn more on IOS as I think that the SDM although helpful in getting started is not a full config tool and may use defaults which are not suitable for your setup.

One last thing are you connecting by both the console and TCP/IP methods at the same time (this is where I noticed the prob mostly) e.g. console connection via serial and SDM connection via TCP/IP?
