Extreme Discovery Protocol

NOTE
When a mirrored port is configured, the forwarding database for items being mirrored (e.g., ports or
VLANs) is automatically cleared if the link status on the mirrored port changes. This clearing results in
some temporary flooding until the normal learning process completes. Removing or inserting a probe
device into the mirror port may appear to cause flooding, but this temporary condition is normal.

Summit 400 Switch Port-Mirroring Example

The following example selects port 3 as the mirror port and sends all traffic coming into or out of the
switch on port 1 to the mirror port:
enable mirroring to port 3 tagged
configure mirroring add port 1
The following example sends all traffic coming into or out of the switch on port 1 of default to the
mirror port:
configure mirroring add port 1 default

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. EDP is also used by the
Extreme Standby Router Protocol (ESRP). Information communicated using EDP includes:
• Switch MAC address (switch ID).
• Switch software version information.
• Switch IP address.
• Switch VLAN-IP information.
• Switch port number.
EDP is enabled on all ports by default.
To disable EDP on one or more ports, use the following command:
disable edp ports [<portlist> | all]
To enable EDP on specified ports, use the following command:
enable edp ports [<portlist> | all]
To view EDP port information on the switch, use the following command:
show edp

Configuring Automatic Failover for Combination Ports

The Summit 400-48t allows you to configure all of the 1 Gigabit fiber ports and the first four
10/100/1000 copper ports for redundancy. For an introduction to this feature, see "Uplink Redundancy"
on page 27.
