Airprint is quieting after an hour on IAP-225's

Hello everyone,

 

I wanted to post this incase anyone else runs into the same issue. We have the Following:

Dell W-AP225 Instant Version: 6.4.4.3-4.2.2.1_53878

ClearPass Policy Manager 6.5.5.78974 on CP-VA-500 platform

 

All of our AirPrint printers stop communicating with the virtual controller after about 60 minutes. We would have to restart each of them to become visible again. But sure enough, a short time later, they would stop working. 

 

We just see the mDNS traffic just drop right off of the virtual controller.  We have worked with Dell Pro Support and Aruba Engineering with no luck at all.  Any thoughts?

Not sure of the ticket number since we go through Dell Pro Support and they loop in Aruba engineering.  I will ask on Monday.  Here is the Dell SR: 921725557 in case you can cross reference the number.

I cannot access Dell Ticket Numbers.

 

What kind of print server device is this?

Did you try having Airgroup Off?

Are the printers in the same VLAN as the users?

The printers are Xerox, Dell & Presto


There are at least 4 different VLAN's involved:

VLAN for Printers & Servers

VLAN for IAP's

VLAN for Personal Wireless Devices

VLAN for School owned Wireless Devices


Airprint works great for about an hour!


I don't think we tried disabling AirGroup, but I will check.

Is there a print server with queues in the picture, or are all of your devices using Airprint?

 

If the printers and users are not in the same VLAN, don't turn off Airgroup because they won't be able to communicate.  If your IAP225s are replacing a previous deployment, you would not be able to print using Airgroup if your users and devices were not in the same VLAN....

The last one mentioned Presto is a print server. The others two are AirPrint printers.

Are the Airprint servers on the same VLAN as the users?  Are you having problems with the print servers going offline, as well?

The AirPrint Servers is on another VLAN. The print server is having the same issue.

Can the clients ping the print server and airgroup servers, even though they seem to be offline?

 

 

So if the print server is having the same issue, it is quite possible that you are not allowing the correct protocol between the users and the print server.  Typically a print server needs SNMP between the users the print server to query the print server, in addition to the printing protocols.  You might need to find out from the print server manufacturer what is needed, or have your clients as unrestricted so that there is nothing blocking them.
