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:

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).
