5508 WLC Interface Groups

We have not configured or used interface groups in our wireless deployments, and I am just curious if there are any issues or caveats experienced with using these? We have a few instances where we have setup a /23 network for a specific wlan. I undertsand this increases broadcasts. Would interface groups be preferred over using a /23 or even maybe a /22 to accomodate addressing?

By default, the WLC will not forward broadcast. There are pro's an con's to interface groups... if your doing multicast, that can be an issue unless you specify an multicast vlan. I have used interface groups because customer standardize on /24, so I would combine a bunch of /24's to create an interface group. I have customers with /23 and /23 and others with no issues... but I look at it as on the wired side. You okay with /23 and or /22 on the wired side?

Thanks,

Scott

You are good.... /23 isn't bad at all. I have to deal with customers who have /16's and wireless and wired on the same subnet:(

Thanks,

Scott
