Remote Port Mirroring

    Hi,

    I need to capture traffic for a device on Switch-A. Currently, Switch-A connects to Switch-B, which connects to Switch-C.
    My monitoring server is connected to Switch-C.

    The links between these switches are trunk links (aggregated in some cases), with production VLANs on them.

    My question is, if I want to add a 'remote-capture' VLAN to each switch, do I have to (or should I) have a separate trunk link to my production traffic?
    I understand the risk of putting a load on the link, but we're talking about very small amounts of traffic here.


    Thanks for your advice

    Hi Luke,

    As long as you have enough bandwidth available on the trunks you can use the same interface. If you see that this might affect production, or don't want it to cross the production network then you might want to have separate links for this traffic. As such, there is no requirement to have a separate link for the remote-vlan option.
