Emerson Smart Switch - Port Mirror Setup

We are running Emerson RM-100 switches and would like to set up one of the free interfaces to mirror the uplink.

What I have found so far is that this feature can be set up using a telnet session, however, I am not exactly clear on the proper command structure.  For my particular use case, I would like to mirror 1.1 to 3.8

The switch gives me this breadcrumb but I would feel better if someone had an example for me to reference.

  'monitor session <session-id>

    {mode | {destination|source} interface <slot/port> }'.

Does anyone have additional information about this command?

  Instructions on how to set up mirroring on DeltaV Smart Switches is available in KBA NK-1800-0430. Note that you need firmware v8.0.13 or higher to enjoy mirroring on DeltaV Smart Switches.
  
  Mirroring is done using a simple to follow wizard via the CLI access (telnet or SSH). The wizard is launched with command "deltav monitor" and then follow the steps which will allow you to select ports to be mirrored and probe port (where mirrored traffic will be sent to) and the configuration will be saved before ending the wizard.
  
  Keep in mind that the probe port shall never be connected to the DeltaV network, it must go to a separate system such us the Network Security Monitor for DeltaV systems. Injecting mirroring traffic into the DeltaV ACN will result in a storm at the ACN level which will likely impact system performance or even cause process disruptions.
  
  Emerson's local service teams can help designing and implementing such configurations.

  In reply to Alexandre Peixoto:

  Ahh, i was missing the DeltaV part and only running the monitor command.

  It was straightforward after that.  Attached is an example for future reference.
