Hi, I'm not sure I understand

Hi, I'm not sure I understand the new DFS function correct.

(5500-1) >config 802.11h smart-dfs ?
enable Enable non occupancy time doubling for Radar interfere channel.
Disable Disable non occupancy time doubling and use legacy time (30 mins) for Radar interference channel.
Default state: enabled
Use disable to match legacy DFS behavior

Does this mean, on the old code it will not re-use the channel for 30 minutes, while on the new release that time doubles by default to 60 minutes?

Hi

>Does this mean, on the old code it will not re-use the channel for 30 minutes, while on the new release that time doubles by default to 60 minutes?

Correct. On releases 8.1 and lower, the channel was blocked for reuse for 30 min, as per DFS regulatory requirements

on releases 8.2 and higher, if the channel gets repeated DFS triggers, it will be blocked longer, to avoid using it on DCA channel assignament

With this command, you can disable the new behavior, and the WLC will work as in 8.1 DFS mechanism
