The Extreme Discovery Protocol (EDP) is used to locate neighbor Extreme Networks 
switches connected to the Summit Virtual Chassis. When running on a normal switch 
port, EDP is used to by the Summit switches to exchange topology information with 
each other. Information communicated using EDP includes the following:
Switch MAC address (switch ID)
Switch software version information
Switch IP address
Switch VLAN-IP information
Switch port number
Summit Virtual Chassis identifier and port number
Listing of all virtual chassis identifiers
EDP cannot be disabled on ports that are connected to a Summit Virtual 
Chassis.
When a Gigabit Ethernet port is configured to be connected to a SummitLink port on a 
Summit Virtual Chassis, the Activity LED on the Summit flashes once per second, even 
when no traffic is present on the network. The flashing Activity LED indicates that EDP 
is running successfully between all of the Summit switches connected to the Summit 
Virtual Chassis.
