Purdue is an all-Cisco shop and we've been using interface groups for a few years now. We use them our main 1x SSID and also with AAA override on eduroam to put Purdue users into the same set of VLANs as the 1x SSID (consistent access experience). It's worked very well so far. As Timothy said: it is harder to remove interfaces to the group that to add them. It requires disabling any WLAN using the group. I've taken to scripting it out to reduce downtime whenever we have to remove an interface.
Another neat use of the group is moving clients to a new set of VLANs. We’ve done that in the past by adding the new ones to the group and then disabling DHCP services on the old ones. The controller will eventually stop using the old ones and then they can be removed from the group. -Brandon From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:[email protected]] On Behalf Of Timothy Burns Sent: Thursday, August 25, 2016 8:33 AM To: [email protected] Subject: Re: [WIRELESS-LAN] Cisco interface groups I started using them minimally(only 3 interfaces to the group) here when we implemented eduroam on our campus. So far I haven't seen any issues. My plan is to start using them more. Currently, we separate our subnets per building, so my thought is to begin combining them into groups in hopes to make roaming easier on the clients. The only issue I have run into and its not really an issue is that it is very easy to add interfaces to a group, but not so easy to remove them. Just something to keep in mind as your testing and putting it into production. On Thu, Aug 25, 2016 at 6:50 AM, James Helzerman <[email protected]<mailto:[email protected]>> wrote: Hi. For those using interface groups on Cisco WLC, could you share any experiences good or bad that you have had? We are exploring the use of aaa override and return the interface group name rather than vlan.
