Hi community

I'm a little bit confused why UC500 crash when a wireless phone connecting.

I tried it with a 7921 and a 7925 Phone, both crash the system.

Data wireless-connection works fine

UC520 SR 8.0.2 with integrated wireless access point UC520W

  • Cisco Employee,

Can I suggest that you need to log a case for this problem.  I had a look at the crashinfo, and this looks suspiciously like a software defect CSCtb44167.  The problem is, if I am reading the defect details properly, then the fix for this problem is already supposed to be in the image you are running. :(

So there are a couple of alternatives here:

1. I've misread the defect details and the fix is not in the release you are running

2. I've read them correctly and there is a problem with the fix

3. I've picked the wrong defect

To a certain extent though, it doesn't matter, as the tech support guys are the ones who can address this problem regardless of which alternative is in play here.  Unfortunately, if it is CSCtb44167, then there is no real workaround other than removing radius accounting from the configuration.  Is that an option for you?

Thank you Dave

It looks really like problems with radius. I will check that on an other system. I've got my workaround with an external radius server and it works well.
