set port mirroring {create | disable | enable} source destination}
Parameters
Defaults

list after a reboot.
"MAC addresses will be learned for packets tagged with the mirror VLAN ID. This will prevent the
ability to snoop traffic across multiple hops.
create | disable |
enable
Creates, disables or enables mirroring settings on the specified ports. By
default, port mirrors are enabled automatically when created.
source Specifies the source port designation. This is the port on which the traffic
will be monitored. Up to 8 source ports can be specified. For a detailed
description of possible port-string values, refer to “Port String Syntax Used
in the CLI” on page 11-1.
destination Specifies the target port designation. This is the port that will duplicate or
“mirror” all the traffic on the monitored port. Only one destination port
can be configured per stack, if applicable.
For a detailed description of possible port-string values, refer to “Port
String Syntax Used in the CLI” on page 11-1.
