Hi Sachin,

The nicDevId() you see is coming from
prepareNetworkElementCommand(IpAssocCommand cmd) in CitrixResourceBase in
case of Xen.

You would see this:

                if (addVif) {
                    // Add a new VIF to DomR
                    String vifDeviceNum =
getLowestAvailableVIFDeviceNum(conn, router);

                    if (vifDeviceNum == null) {
                        throw new InternalErrorException("There were no
more available slots for a new VIF on router: " +
router.getNameLabel(conn));
                    }

                    nic.setDeviceId(Integer.valueOf(vifDeviceNum));

                    correctVif = createVif(conn, routerName, router, null,
nic);
                    correctVif.plug(conn);
                    // Add iptables rule for network usage
                    networkUsage(conn, routerIp, "addVif", "eth" +
correctVif.getDevice(conn));
                }

And nic.setDeviceId() should set the public nic id(which should be 2 in
your case) to it.

And what's the XenServer version you're using? Could you help to debug it
further more? Sadly we cannot reproduce it in our lab...

Thanks!
