T301N on a zone director

robert_mc_nicho — Fri, 07 Apr 2017 18:00:56 GMT

I am running 8 -T301n ap's on a zone director 3025, but when i get 20 users on them the CPU in the unit shows it is running at 100% and the whole system bogs down, any suggestions

Are you saying the CPU of the ZD is 100%? If so are you tunneling everything back to the ZD?

No it is the CPU on the T301 units, I am running 17 R700 units also through the same ZD (for a total of 25 ap's)They do not bottleneck the system. The units are connected back to the ZD via Fortigate 1 GB switches.

So the last time I had 100% CPU on my APs was due to multicasts/broadcasts. Check out my response in this article: https://forums.ruckuswireless.com/ruckuswireless/topics/access-points-dropping-suddenly

OR maybe some of your clients have high retry rates? Not sure grapsing at straws. Could maybe be a firmware issue, if your R700's have no issues, but your T301's do.

Hi Todd,

Do you still see CPU spike even after disabling directed multicast feature on the AP?

I didn't disable it. I found the offending client and updated it's drivers.
