Hi Jeff,

If you go to Monitor / Events you can filter on "wifi1" and you should be able to see DFS events quite clearly. You'll see which AP, When and what channel.


Kind Regards,

Nice information

With our old wireless network we got a lot of problem with DFS. I have been looking at the event and can't find any.

what will the the text be in monitor/event if there is problem with DFS channel ?

Kind regard

Hi Jan

We have the ability to see the number of detected radar signals on an access point via CLI;

AP130#sh int w1 | inc dfs
DFS=Dynamc Frequency Selection; CU=Channel interference;
DFS=enabled; Number of detected radar signals=3

You would need to correlate this with the logs in hive manager to see when they occurred...it is possible to output this information to a syslog server from the AP.  You can filter the wifi1 logs in hive manager as Gary mentioned previously and export to csv file for analysis.

I know this is old post, assuming DFS is disabled, would an AP still detect radar signals?

show wifi0

# some output omitted

DFS=disabled; Number of detected radar signals=0; -- I'm referring to this bit of output
