It would seem to have an advantage on a bridge where you are passing a vlan through multiple interfaces since 'vlan777' cannot represent both the incoming and outgoing vlan interfaces, but em0.555 and em1.555 seem quite logical. It gives an easy way to differentiate the same vlan on more than one parent interface. Additionally the native names are shorter which often helps in status reporting utilities that truncate the name for display. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
