Port Mirroring commands are used to configure, enable and disable the monitor
port. When enabled, network packets being sent and/or received on a target port
are duplicated and sent to a monitor port. By attaching a network analyzer to the
monitor port, you can collect detailed information about your network
performance and usage.

Table 209.
Port‐Based Port‐Mirroring Configuration Options
Command Syntax and Usage
port­mirroring monitor­port <port alias or number> mirroring­port
<port alias or number> {in|out|both}
Adds the port to be mirrored. This command also allows you to enter the
direction of the traffic. It is necessary to specify the direction because:
If the source port of the frame matches the mirrored port and the mirrored
direction is ingress or both (ingress and egress), the frame is sent to the
monitoring port.
If the destination port of the frame matches the mirrored port and the mirrored
direction is egress or both, the frame is sent to the monitoring port.
Command mode: Global configuration
no port­mirroring monitor­port <port alias or number>
[mirroring­port <port alias or number>]
Removes the monitor port. The mirroring­port option only removes the
mirrored port.
Command mode: Global configuration
show port­mirroring
Displays the current settings of the monitoring port.
