AP disappeared from Controller

Hi...

Controller : Aruba 650 OS 3.4.2
AP : AP65
License : 16 Access Points

I was testing with initial configuration with the AP directly connected to the controller port. The AP was able to get an IP from the DHCP server.

Now after I change the Access point role to mesh point it disappeared from the controller and it status after entering 'show AP database' is flagged as down

I used the 'clear gap-db ' to remove it from that database in the hope that I can rediscover the AP again, but no luck.

I enabled a DHCP server on the controller but still no IP was received by the AP.

Is there anything I can do through the controller to discover this AP, perhaps a manual entry? Currently I cannot console to the AP (no Y splitter cable, soe as I understood doent work on gig port, no power cube :( )

Even I am noticing the AP is heating up more than before

All help is appreciated

Re: AP disappeared from Controller

A mesh point is not supposed to be plugged in. It is normally the mesh access point that uses the radio to send traffic back to a mesh PORTAL, which DOES have its ethernet plugged in. If you configure another access point as a mesh portal, it should be able to see the mesh point, radio-to-radio and contact it. You will then be able to to what you want to do.

The reason why SOE does not work on a gig port is that the pins normally used for serial over ethernet on 10/100 are in use on a gig port. If you co

Re: AP disappeared from Controller

Thanks Collin for the explanation. I will try to use a mesh portal to try to get to the original AP.

Meanwhile I was able to make a custom 5v a/c adapter with the help of an electronics guy. I was able to power up the AP but nothing came up on the hyper terminal. I used the same console cable that I successfully use with the controller, pins 4,5,7 (if I remember) of the DB9 connector going through a straight utp cable to the AP's ethernet port.

Is there a different cable? I have followed this link http://airheads.arubanetworks.com/vBulletin/showthread.php?t=1855 and I will try creating a cat 5 cable with the pinout given in the diagram (console side 3,4,5,,6 <--> AP side 4,5,7,8)


Thanks again

Re: AP disappeared from Controller

The custom console cable worked :) We followed the pin out in the AP 65 Datasheet and things were find, although all that appeared on the HT was ascii like characters, but nonetheless I typed purge, save, reset and the AP rebooted.

Once I plugged it in the controller it received an IP and my laptop saw an aruba-ap ssid, although I never defined it, but it seems I am getting somewhere.

Thanks again

aruba-ap is the ssid used in the default ssid-profile that is used inside the default virtual-ap profile which in turn resides in the default ap-group :)

Re: AP disappeared from Controller

yes, all the way until ArubaOS 6.1 a new controller install automatically broadcasts "aruba-ap" for any access points in the "default" ap group. That would be very new access point that hits the controller. In ArubaOS 6.1 and beyond, it no longer does that.
