Dedicates a port on the switch to be the mirror output port.

Syntax Description

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.

is added to the command syntax.

• Supports modular switches.

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).
