Whilst I haven't specifically done this, I have done diskless booting on a wired NIC and then switched to a wired/wifi lagg. Have a look at http://www.bugs.au.freebsd.org/dokuwiki/doku.php/laggdiskless >I concede that under this structure lagg's loadbalance or LACP are probably >not going to work. FEC & LACP require support at both ends and so won't work. loadbalance & roundrobin should work but aren't really appropriate unless your interfaces are identical. >In general, as soon as lagg is brought up, NIC pool no longer responds to >pings and gives an "I'm busy now" message. Yes. Once you create the lagg, the interfaces comprising it will no longer work standalone and you can't atomically migrate the IP address =66rom re0 to lagg0 - hence the script linked from the above page. --=20 Peter Jeremy --liOOAslEiF7prFVr Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk90DVYACgkQ/opHv/APuIde1gCgtZqapZoXKnt+0P4WLxoutfe4 VbEAni62yKnjrirkk5JPBrIfWtuAcX4O =JSbv -----END PGP SIGNATURE----- --liOOAslEiF7prFVr--
