Update on 7.4.100.0 stability. We increased our license count on our 5508s running 7.4, and so we pulled our old WiSMs out and put the APs that were on the WiSMs associate and upgrade to 7.4 on the 5508s. We have a mix of 1131, 1242, 3500, and 3600.
Once the 5508s were more heavily loaded we started a seeing a few random client dropouts and looking through the logs an unusual RRM message we'd not seen before. Called Cisco and they made available an engineering build 7.4.100.6, which we upgraded to immediately and so far it seems to have solved the problems. One thing on Apple AirPrint I've noticed with 7.4 is that though AirPrint works fine on iOS devices, AirPrint printing doesn't work on Macs (10.7 and later). Of course, you don't need AirPrint on a Mac since you use a driver and do LPR/LPD all day long. But it seems to me there may be some client side issues with AirPlay on Macs, or since it isn't really documented from what I can see maybe there are some underlying requirements for AirPlay with OS X. There are no requirements for iOS AirPrint (multicast isn't needed) other than to have bonjour snooping on the WLC. ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
