3G router Hang

Unanswered Question
Jul 26th, 2010

We have a problem for a router with 3G HWIC. When the GSM network is down, the router hang after 40 min.We could not access the router and we  have to power off and on the router to work again.

Is it solved in some IOS release, or it is a configuration issue?

I have this problem too.

What model router are we talking about? What IOS version are you running?  What is the part

number of the HWIC?

When you say the GSM network is down, does that mean the port is admin down or the interface is down?

If the router has truely hung then the only way to figure out what is really going on is to obtain k-traces in rommon. The procedure is described here:

Many times a router is reported as hung when a VTY cannot be reached. Could you access the console before the router was reloaded?
