Port Mirroring to Multiple Ports - Duplicate Traffic?

  • 1.  Port Mirroring to Multiple Ports - Duplicate Traffic?

    Posted 01-05-2018 22:11
    Having 2 "to ports" configured in a mirror, are they identical duplicated traffic from the mirror ports in the port-list or are the 2 ports load balanced? I have 2 ports configured to send to an Alienvault for logging, so is the AV server receiving duplicate traffic?

    create mirror "AlienVault"
    configure mirror AlienVault to port-list 1:44,2:44 loopback-port 1:49
    enable mirror AlienVault
    configure mirror AlienVault add port 1:1,2:1 ingress-and-egress
    configure mirror AlienVault add port 1:2,1:11-19,1:23,1:41,2:2 ingress-and-egress
    configure mirror AlienVault add port 1:3,2:3 ingress-and-egress
    configure mirror AlienVault add port 1:47-48 ingress-and-egress

    Hi Aires,

    The port 1:44 and 2:44 will have the same traffic (duplicated) and not load balanced.

    Hi, Aires!

    Details you can find here - https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-mirror-to-multiple-ports

    "
    • The port-list is a list of monitor ports that transmit identical copies of mirrored packets.
    "

    Thank you!

    configure mirror AlienVault to port-list 1:44,2:44 loopback-port 1:49

     

    Hi all from the configuration , can anyone explain how to get the loopback-port on the switch 

    or rather how do one identify the port in this example scenario ?
