Chapter 5. Configuring Slots and Ports on a Switch | 141
NETGEAR 8800 User Manual
To enable mirroring on multiple ports, use the following command:
enable mirroring to port-list <port-list> loopback-port <port>
The port-list is a list of monitor ports which will transmit identical copies of mirrored packets.
The loopback-port is an otherwise unused port required when mirroring to a port-list. The
loopback-port is not available for switching user data traffic.
To disable mirroring, use the following command:
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.

enable mirroring to port-list 2:5-2:7 loopback-port 3:1
configure mirroring add port 6:5 ingress
Verifying the Mirroring Configuration
The screen output resulting from the show mirroring command lists the ports that are
involved in mirroring and identifies the monitor port. The display differs slightly depending on
the platform.
Remote Mirroring
Remote mirroring enables the user to mirror traffic to remotely connected switches. Remote
mirroring allows a network administrator to mirror traffic from several different remote
