Extreme Discovery Protocol (EDP)

EDP is a vendor proprietary protocol from Extreme Networks. It is used to send information like system MAC, device name or VLAN information to neighboring Extreme devices. It is also used to transport "higher level" protocols like EAPS and ESRP.

Capture Filter

EDP cannot be specified directly as a capture filter. It looks like all EDP traffic is sent to destination mac addresses starting with 00:E0:2B:00:00:

ether[0:1] = 0x00 & 0xfe and ether[1:1] = 0xE0 and ether[2:1] = 0x2B and ether[3:1] = 0x00 and ether[4:1] = 0x00
