1000 7921s / 20 WLCs / 1000 1130 APs

[asafayan]

Our environment:

- 1,000 7921s on phone load 1.1.1

- AP1130s with 15 WLCs on 4.2.130.0

- WCS version 4.2.110.0

We're experiencing a lot of 7921 issues that are resolved with a reboot of the phone.

Is anyone experiencing this?

Does anyone have a recommendation on phone load and WLC/WCS code versions?

It's hard to fantom what is causing the problem with such limited information.

What issues with the 7921 are you having?

[asafayan]

I hear you.

I'm not directly involved with the group that troubleshoots the WLAN environment anymore - so I was more hoping to find someone with a similar sized environment with the same platforms so that I could get a phone load and WLC version recommendation more than troubleshooting specific issues.

[Leo Laohoo]

Give us some more details and we'll see how we may be able to assist.

We recommend 5.2.157.0 and later for the WLC as it has TCLAS support and at least 1.2(1) for the 7921, where the latest release is 1.3(2).

Other than that without a symptom description it is hard to help you troubleshoot the issue.

See the 7921 Deployment Guide to ensure your deployment and WLC configuration are in compliance with the guide requirements.
