Problems with Verifone VX670 wifi payment terminal

We have deployed AP-105 as RAP stations into several restaurants. SSID is bridged since these devices need to communicate with local cashier system in each location. Security is WPA1-PSK since its the strongest encryption these devices support. Payment terminal also has static IP since it was requirement for cashier system. Aruba shows that these connect with B radio. 

 

Now the problem is that these terminals seems to be dropping from wlan and not be able to automatically connect again. Signal etc are good when these are connected and I cannot find any real problem. Techincal support I'm getting from local Verifone support is very thin so I'm asking here if theres some special tricks I should do with these?

Re: Problems with Verifone VX670 wifi payment terminal

Hmm, that could be a number of things. The first suggestion I have is to put the device into debugging so you can get logs that may point you in a specific direction. Do a "show user-table"; on the controller and copy the Mac address of one of the disconnecting devices. Then type "configure terminal logging level debugging user-debug [mac address]". From there, you can do "show log user-debug all | include [mac address]" after the device does one of its intermittent disconnects. You can post it here for thoughts from the community, but if this is a critical issue, I'd recommend gathering those logs and calling 1-800-WIFI-LAN to open a case with TAC.

Re: Problems with Verifone VX670 wifi payment terminal

Is it same as setting debug for client in webgui? I did it earlier, didnt got any results when posting initial question but now there seems to be some:

 I also noticed that these devices seem to drop from associated clients but they may come back if I ping them from the LAN side. 

 

EDIT:  00:0b:4f:CC:CC:CC is the cencored mac of the client. 

 

EDIT Controller is 620 and firmware is 6.1.2.7

Re: Problems with Verifone VX670 wifi payment terminal

Is "APNAME-CENCORED" representing one AP or multiple APs? You can do "show auth-tracebuf Mac [mac_address]" to see if the are any issues with the WPA key exchanges. You can see there ar several "death from sta"tion messages, indicating that the client is initiating deauthentication from the AP. is the device going idle? What does "show aaa timers" indicate in your configuration? Is the client running the latest available firmware?

Re: Problems with Verifone VX670 wifi payment terminal

#show aaa timers

User idle timeout = 300 seconds
Auth Server dead time = 10 minutes
Logon user lifetime = 5 minutes
User Interim stats frequency = 600 seconds

 

Auth-tracebuf comes empty. In this case APNAME-CENCORED reprsents single AP. I have several AP's with same SSID but they all are in separate locations. And yes I think the device goes into sleep mode when its not used. I have no control over device firmware, its embedded device:

Re: Problems with Verifone VX670 wifi payment terminal

If it's going to sleep for more than 5min, the controller (based on the user idle timeout) will remove the user from the controller, which I believe correlates with those "deauth to sta" messages.

 

It may be a matter of device behavior at this point. I'm assuming that the scanner goes to sleep for 5+ minutes and is deleted from the controller. When an employee at the restaurant then goes to swipe a card, what's the order of events? One would hope the device is smart enough to FIRST associate and ensure it has an IP address, THEN attempt to transmit the card swipe data.

 

I worked with some ticket scanners in the past where they wouldn't wait to ensure connectivity before trying to send data. Of course, the data submission failed and it would display failure on the device. The manufacturer had to address it in the code (i.e., first check for connectivity, then submit).

 

Good luck!

Re: Problems with Verifone VX670 wifi payment terminal

What I see, user puts credit card in -> inserts pin -> device tries to connect bank for card validation and local system for table information. If connection fails only way to resolve is to boot device by removing battery. So it most probably does not verify connectivity. For a bubblegum fix I try to increase Aruba timeout to 15min.

Re: Problems with Verifone VX670 wifi payment terminal

Finally got some answers. The payment terminal indeed does not check status of connection before trying to push data to the network. Only way is to press F2 which makes it to check network connection. Reading between lines they most probably wont change this. 

 

Can I adjust time-out value only for one virtual-AP?

Re: Problems with Verifone VX670 wifi payment terminal

:-/ hmm. As far as I know, the aaa timers are global per controller. Perhaps an Aruba PM can comment...?
