ERS 4548GT-PWR

[teletechman]

Does anyone have any experience with these switches. I have a customer that has IP Phones that will re-register for no reason, TS said it looks like routing. We have gone back to the IT guys and they say all is ok. I just need someone that can look over a config and tell me if it looks OK. I have limited experience in this area but am trying to get the training. I can post the config if anyone can help.
Thanks Mike

Shot in the dark but I heard of a bug with Avaya IP phones and a that switch on a particular release (very recent). Check the software release on the switch and look at the bug report for it.

I know a bit about the switches. Post the output from a show run command and I'll see if I see anything that stands out.

The config looks ok.

I program them a bit differently, but there are plenty of different ways that I've seen these set up.
What happens when these phones reregister? Do they reboot and start again immediately? Or do they hang at the Discover screen for a bit?
Switch software could be an issue too. I'm not sure what version had the problem, but there definitely was one like Dan1765 mentioned.
Currently I have a switch that runs 5.6.2.026 software and its fine. There is a newer release available, but I haven't upgraded to it yet.

If the phones are just dropping and reregistering, I'd upgrade the switch and see if that fixes it. If you do that, remember to upgrade the diag image before the software/agent code.

Ok thanks
