SV: [WIRELESS-LAN] Cisco Wireless Interface Groups
What version are you running on jour WLC? I know that there were hashing problems on older versions off 7.0 that resulted in that when a client reassociated it didnt come back to its former subnet. Try newer versions of 7.0 or 7.2 and Ill guess that it will work. It solved my problem. ;) Cheers Anders Nilsson Umeå university SUNET Sweden Från: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] För Vikki Cutrone Skickat: den 15 februari 2013 20:13 Till: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Ämne: [WIRELESS-LAN] Cisco Wireless Interface Groups Hello All, I recently configured multiple /24 subnets into a wireless interface group on my controllers, in an effort to cut down on multicast as well as increase the IP address space. It seems to be working but DHCP addresses are still being consumed at an alarming rate. Is anyone else using the interface group feature? and if so is it working as expected?

Version 7.2.111.3 That seems to be exactly what is currently happening. On Fri, Feb 15, 2013 at 2:23 PM, Anders Nilsson anders.nils...@adm.umu.sewrote: What version are you running on jour WLC?

VLAN select feature is working good here on: 7.2.110.8, 7.4.100.0, 7.4.103.3 and now on 7.3.112.0. ;-) just fyi, tried 7.4.100.0 and small issue with RRM, (running at low signal strength) and with the 1142 model access points. Patch for the RRM and all was great, seeing more 5GHz N clients with 7.4.103.3 code than on 7.2.x and 7.3.x. The 1142 random rebooting continued though, patch on its way. Went to 7.3.112.0 and all is good since, running on 5508 controllers and AP1242, AP1252, AP1142, AP3502 access points. jim On 2/15/2013 2:27 PM, Hurt,Trenton W. wrote: http://www.cisco.com/en/US/products/ps10315/products_tech_note09186a0080bb4900.shtml In WLC release 7.2, the VLAN Select feature (which is supported only on the newer WLCs like 5508, WiSM-2, 7500, and 2500) was modified and now supports VLAN Select with a new modified algorithm.

As Anders hinted, the mac hashing feature to solve dhcp exhaustion introduced in 7.2 was backported to later versions of 7.0 code (7.0.220.0 perhaps). We're running vlan select happily on 5508s on 7.2 and WiSM-1s on 7.0 and it works well on both.
