    Hi everybody.

    I'm stuck with RSPAN configuration. I have three switches (image below). I'd like to configure RSPAN through.



    enable sharing 25 grouping 25-26 algorithm address-based L2[/code]
    Is it right configuration?
    create mirror "RSPAN"
    configure mirror RSPAN to port 25 remote-tag 99
    configure mirror RSPAN add port 20 ingress-and-egress[/code]
    Or I should do something like?
    create mirror "RSPAN"
    configure mirror RSPAN to port 25,26 loopback-port 24 remote-tag 99
    configure mirror RSPAN add port 20 ingress-and-egress[/code]
    Moreover, I got this message when I tried to use second configuration example.
    Error: Port 25 cannot be added to VMAN as untagged because the port is a tagged VMAN member and a tagged VLAN member.
    Mirror-to ports could not be added to mirroring VMAN![/code]

    Because port 25 and 26 are an MLAG they are logically 1 single port. I think you should be able to your first option.

    Unfortunately no.
    # enable mirror "RSPAN"
    Error: Port mirroring cannot be enabled on a trunk member port 25[/code]

    From User Guide 15.7
    "A mirror port cannot be a LAG."
    It's from limitations.

    Thank you!
