Monitoring and Analyzing Switch Operation
Traffic Mirroring
This command assigns a mirroring source to a previously
configured mirroring session on a source switch. It specifies the
port and/or trunk source(s) to use, the direction of traffic to
mirror, and the session identifier.
The
no
form of the command removes a mirroring source
assigned to the session, but does not remove the session itself.
This enables you to repurpose a session by removing an
unwanted mirroring source and adding another in its place.

range of consecutive ports (
