No, that has got to be a mistake. You can use the same ID once per underlying device: # ip -d link list 4: vlan0@dummy0: mtu 1500 qdisc noop state DOWN link/ether d6:1f:c0:bd:b2:ec brd ff:ff:ff:ff:ff:ff vlan id 1000 6: vlan1@dummy1: mtu 1500 qdisc noop state DOWN link/ether 8a:17:13:5d:87:1a brd ff:ff:ff:ff:ff:ff vlan id 1000 If it doesn't work for you, please post the full commands and ip -d link list output you used. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
