Do APs reboot after 802.11b/g Global Data Rate changes (Disabled/Supported/Mandatory)

[ritchie65]

If a change to the Data rate options in 802.11b/g Global Parameters from Disabled to Supported or Mandatory is made, do the  APs have to reboot to implement the new configuration?

On WLC, no. On EWC, no idea. 

One important thing though, you first need to disable 2.4 or 5 GHz before you can change the rates and afterwards enable it again. So the clients will drop off while you change it, do it in a maintenance window. 

So do it first for one frequency, wait some 30+ seconds and then do it for the other frequency. That way the clients would have less down time.

I believe the radios will reset which will cause a small outage for a few seconds.

AP won't reboot, All clients joined(on all WLANs) to the AP radios get kicked momentarily and join back.

Just to add... the interruption is the same if you make changes to the wlan.  So depending on your devices and how fast they reconnect, will determine your outage.  There can be devices that might take longer to re-associate and possibly some that my need to be bounced.
