I setup v-wire with q tag trunk ports on the 5000 series for a data center deployment.

this can be as simple as outlined in this document.  Where there is only two zones and all tags are just permitted through the v-wire.

Trunked Traffic in a V-Wire

If you want more control, you can create a subinterface for each q tag on the v-wire.  These can then be placed onto their own v-wire pipe and assigned zones separately from the other q tags on the trunk port.  This also prevents the automatic passing of additional tagged frames on the trunk without the explicit configuration of the sub-interface and v-wire pair.

  • Create the v-wire for the tag
  • Create the sub-interface on both physical interfaces and assign the tag and the v-wire
  • Assign each side of the v-wire to the desired zones
  • Rules will then apply by zone assignment of the particular v-wire pairs
