User Guidelines
This command enables traffic on one port to be copied to another port, or between the source
port (src-interface) and a destination port (the port being configured). Only a single target port
can be defined per system.
The port being monitored cannot be set faster than the monitoring port.
The following restrictions apply to ports configured to be destination ports:
The port cannot be already configured as a source port.
The port cannot be a member in a port-channel.
An IP interface is not configured on the port.
GVRP is not enabled on the port.
The port is not a member in any VLAN, except for the default VLAN (will automatically be
removed from the default VLAN).
