    What hypervisor are you using?
    
    
    If you're using KVM, you could add a vlan VIF into the bridge in question and then dump that traffic somewhere via a replicated span on your switch.

    Subject: TAP/SPAN...
    
    We’ve got a client who would like to ship a copy of all packets that pass through their virtual router to an appliance (that we’d place on their VLAN).
    
    I’ve searched a bit (I’d hoped to see some mention of it in the users list) and haven’t found specific references to TAP/SPAN related to CloudStack, is there a convention for such things? I’m a (tiny) little out of my depth, is this the kind of thing that I might find (if it existed) here:
    
    
      *   http://docs.cloudstack.apache.org/en/4.11.1.0/adminguide/networking.html?highlight=network%20service%20providers
    
    At the very least is something like this (a kind of roll-your-own SPAN) possible on the virtual router?

    I wish this had come up at the collab  in Montreal (having JUST been there earlier this week), but so it goes.
    
    Thanks for any consideration/feedback,
    David
