RUCKUS ICX 7150 24P SWITCH UNSTABLE, SWITCHING ON AND OFF PORTS

Hello guys, 

First of all, i would appreciate any workaround that anyone could give me. I have a large Switch network for a LAN of a univerisity campus here. This network is mixed with switchs HP for the distribution layer and ICX7150 for the access layer, that provides ethernet connection for several Ruckus Access point. 

Since day one, we introduce the ICX switchs to the network and configure the APs we have seen that there is an issue regarding the randomly disconnection of the APs, at first, we thought would be the AP configuration or the SZ100 controller. Eventually we discover that the issue could be some sort of problem with the switches, we tried to look up for any kind of trouble and we discovered that maybe could be a RSTP or STP error or phenomenon that could led to randomly switching on and off the ethernet ports, provoking that the APs disconect form the network and get a poorly wifi experiance



We suspect that this could be, and connect the APs directly to the HP distribution switches, and now the building where they are, is steady as should be. 

But it could be certanily another thing. 

What do you think guys?

thanks a lot!

Maybe it is nothing more than a power problem.  Causing the AP to continue to reboot and go through spanning tree again and again.



What firmware are you running on the 7150's???

I ask because with 08.0.70 builds, it auto installs the latest PoE+ firmware, too.

Additionally, do you have the proper network discovery protocol at the edge to detect the APs?

Are you using plain "inline power" (on be default in newer builds) or are you specifically putting the class?


Personally, I would upgrade to a recent build of the FastIron /IronWare OS ensuring you are running 2.1.0 Build 002 or later, and that you at least have lldp turned on with lldp run.

I would try plain, vanilla "inline power" without extra arguments, so the device should get whatever it asks for.

^^^^^^^^^^^^  This is what I would do first.

P.S.  This is what I am currently running though we intend to upgrade to the 08.0.80 branch soon.  If you stick with the 08070 series, I am certain they have at least "C" out by now... and that would be more desirable than "B"

Please look at the syslogs prior to the problem for any potential trigger.

8.0.70c and 8.0.80c are both available now.

If you are using 8.0.61 make sure that you are using the icx7xxx_poe_02.1.0.b002.fw PoE firmware. As mentioned by NETWizz if you upgrade to 8.0.70c the PoE firmware will be upgraded automatically.

Hi,

To check why the AP reboots, log into the AP via ssh when it just restarted and type the commands.
support
support show.

At the end it will provide you the syslog and you should see a bit what is going on.
Otherwise open a case with support and they can check for you.

Regards
Martin

Yes, Martin brings up a great point.  You may want to check the AP logs as well.  The biggest issue is the AP may loose its syslogging upon reboot.  I would certainly set the syslog server on it, too, so you don't loose those logs on reboot.

Thanks a lot guys, actually we did some research in what NETWizz said and found out that the output power was maybe the problem. We applied the command "Device(config)#inline power ethernet 1/1/2 power-limit 30000" and it started to get steady as it should. So we believe that was the problem, a lack of power.
