Protocols used in the Summit WM20 Controller
Summit WM Software uses several protocols. All the protocols are IP based protocols, and as a result
have corresponding TCP and UDP ports associated with them. You must note the TCP/UDP ports that
are required for the proper functioning of the Summit WM Controller and the Wireless APs.
The following table specifies the protocol ports:
