Flapping on Cisco switch in a Ruckus WiFi solution

[alejandro_mend1]

Hi

I have a wifi solution with ruckus, controller 1100 and 47 AP ́s. The ap ́s are disconnecting randomly because of some switch ́s ports are up and down constantly.
The wired network is ok and certified,
But there are many logs registered refers to flapping on the switch.
I have disabled the mesh option on the zonedirector. The processor load on the switch has been decreased after that. But the issue keeps alive.

Could it be related with the cisco switch arp table refresh time?
Is it necessary to get similir time of refresh
Or, What could be the problem?

Do you have mesh features enabled?
If not, and all you're seeing is a lot of mac flapping log entries on your switches, it's likely that you have an issue w/ wifi clients rapidly roaming. (as opposed to a spanning-tree issue)

I just posted this "best practice configs for a high density deployment" question.

See if that helps you.

The mesh features are disable.

Hi Bill. Thanks by the suggestions in best practice.... post.

I will test it. But, I have a question:
How to run steps 2,3 and 4 (ofdm-only, bss-minrate, smart-roam). (on AP CLI or ZD CLI?)

I added another post explaining how to get to the ZoneDirector CLI to enter the proposed "Best Practice" config.

Hi Alejandro,

As Bill said MAC Flap is because of the clients roaming quite frequently which is causing the client MAC to be learnt via more than one AP.

I would like to also mention that there was a known issue on version 9.6.1 which might be what you are having too. Check this out:

I would suggest having the ZD on version 9.7.2.0.9 as that is a recommended version and also the bug fix is present in it.

Cheers,
Rahul
