The features we've found most valuable are the ability to track and sync mac-addresses and switchport information of connected hosts to the the Infoblox grid, and also the configuration backups of managed devices. For our stores, we have the same type of switch in 200 locations. If we want to do a change to baseline confiuration, we schedule it and push it through to all sites at the same time, or in batches. That's what we use it for most.
