Extreme Discovery Protocol
ExtremeWare XOS 11.0 Concepts Guide 79
Switch Port-Mirroring Examples
The following example selects slot 7, port 3 as the untagged monitor port, and sends all traffic coming
into or out of a modular switch on slot 7, port 1 to the monitor port:
enable mirroring to port 7:3 untagged
configure mirroring add port 7:1
The following example sends all traffic coming into or out of the system on slot 8, port 1 and the VLAN
default to the untagged monitor port, which is slot 7, port 3:
enable mirroring to port 7:3 untagged
configure mirroring add port 8:1 vlan default
The following example removes all port-mirroring configuration from the switch:
disable mirroring
NOTE
When you change the mirroring configuration, the switch stops sending egress packets from the monitor
port until the change is complete. The ingress mirroring traffic to the monitor port and regular traffic are
not affected.
Verifying the Switch Port-Mirroring Configuration
The screen output resulting from the show mirroring command lists the ports that are involved in load
sharing and which is the primary port.
Extreme Discovery Protocol
The Extreme Discovery Protocol (EDP) is used to gather information about neighbor Extreme Networks
switches. EDP is used to 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.
To disable EDP on one or more ports, use the following command:
disable edp ports [<ports> | all]
