Note: I did have to add vlan support in my kernel for this, I'm using Intel 1000MT 1000BaseSX (fiber) card to a Cisco Catalyst 2948 which in turn connects on the other side as a trunked port. -- Nathan Vidican nat...@vidican.com _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
