Port Mirroring

This section describes the Port Mirroring feature, which can serve as a diagnostic tool, debugging tool, or means of fending off attacks.

Overview

Port mirroring selects network traffic from specific ports for analysis by a network analyzer, while allowing the same traffic to be switched to its destination. You can configure many switch ports as source ports and one switch port as a destination port. You can also configure how traffic is mirrored on a source port. Packets received on the source port, transmitted on a port, or both received and transmitted, can be mirrored to the destination port.

CLI Examples

The following are examples of the commands used in the Port Mirroring feature.

Example #1: Set up a Port Mirroring Session

The following command sequence enables port mirroring and specifies a source and destination ports.

(DWS-3024) #config

(DWS-3024) (Config)#monitor session 1 mode
