Controller Based WLANs

What causes an AP to display the ?RESTARTING ALL TX? message?

Product and Software: This article applies to all Aruba controllers and ArubaOS 3.3.2.x and later.

The “RESTARTING ALL TX” message means that the AP is on a DFS channel.

When the AP moves to a DFS channel, it is supposed to wait for 1 minute (or 10 on some channels in ETSI) before beaconing. "Restarting all tx" gets printed after the initial non-occupancy time expires.

You can get additional messages, similar to the following, if you have ap-debug configured:
