Extreme Discovery Protocol

The Extreme Discovery Protocol (EDP) is used to gather information about neighbor Extreme Networks switches. EDP is used by the switches to exchange topology information. Information communicated using EDP includes:
  • Switch MAC address (switch ID)
  • Switch software version information
  • Switch IP address
  • Switch VLAN IP information
  • Switch port number
  • Switch configuration data: duplex and speed

EDP is enabled on all ports by default. EDP enabled ports advertise information about the Extreme Networks switch to other switches on the interface and receives advertisements from other Extreme Networks switches. Information about other Extreme Networks switches is discarded after a timeout interval is reached without receiving another advertisement.

Refer to Displaying Port Information for information on displaying EDP status.
