Re: TAP/SPAN...


David,


So I assume the customer is in an isolated network between the VR and their VMs?


If so, just SPAN that vlan to another port on your switch and tap it there.

    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?


      *   https://networkhop.wordpress.com/2016/04/27/port-mirroring-with-iptables/

    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
