ExtremeWireless offers profiles, policies, and tags. The entire architecture is divided into multiple sections like tags, policies, and profiles. If I have two sites, and one site needs to be configured with different SSIDs and radio settings, it's completely different compared to the site. It's not a global configuration, and you can individually divide the sites with the profiles, policies and tags to assign the configurations to the tags of the respective sites. When doing the upgrades, you can do the site-based or location-based things. So that's a very cool feature in ExtremeWireless, which has been running for a long time. Recently, Cisco 9800 models have been offering the same kind of features.
