To continue creating a port mirroring session, specify the name, description, and session details for the new port mirroring session.


  1. Set the session properties. Different options are available for configuration depending on which session type you selected.
    Option Description
    Name You can enter a unique name for the port mirroring session, or accept the automatically generated session name.
    Status Use the drop down menu to enable or disable the session.
    Session type Displays the type of session you selected.
    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.

    Mirrored packet length (Bytes) Use the check box to enable mirrored packet length in bytes. This puts a limit on the size of mirrored frames. If this option is selected, all mirrored frames are truncated to the specified length.
    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.
