    Status

    Use the drop down menu to enable or disable the session.

    Session type

    Normal I/O on destination ports

    Use the drop-down menu to allow or disallow normal I/O on destination ports. This property is only available for uplink and distributed port destinations.

    If you disallow this option, mirrored traffic will be allowed out on destination ports, but no traffic will be allowed in.

    Sampling rate

    Select the rate at which packets are sampled. This is enabled by default for all port mirroring sessions except legacy sessions.

    Description

    You have the option to enter a description of the port mirroring session configuration.
