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.
