Syntax Description
Default
N/A.
Usage Guidelines
Port-mirroring configures the switch to copy all traffic associated with one port to a monitor port on the
switch. The monitor port can be connected to a network analyzer or RMON probe for packet analysis.
The switch uses a traffic filter that copies a group of traffic to the monitor port. The traffic filter can be
defined based on one of the following criteria:
• Physical port —All data that traverses the port, regardless of VLAN configuration, is copied to the
monitor port.
• VLAN —All data to and from a particular VLAN, regardless of the physical port configuration, is
copied to the monitor port.
• Virtual port —All data specific to a VLAN on a specific port is copied to the monitor port.
Up to eight mirroring filters and one monitor port can be configured on the switch. After a port has
been specified as a monitor port, it cannot be used for any other function. Frames that contain errors are
not mirrored.

For version 2.0 and 4.0:
• In addition to the physical port, VLAN, and virtual port, the traffic filter can be defined based on the
following criteria:
— MAC source address/destination address —All data sent to or received from a particular source
or destination MAC address is copied to the monitor port.
For MAC mirroring to work correctly, the MAC address must already be present in the forwarding
database (FDB).
port Specifies the port to be the mirror output port.
