There's also > ng_one2many. I posted instructions a while ago on how to setup ng_fec along with an HP ProCurve switch supporting FastEtherchannel -- the same should also apply for Cisco switches. Be warned that newer HP/Cisco gear has dropped support for FEC in favour of 802.3ad/LACP... http://lists.freebsd.org/pipermail/freebsd-net/2006-September/011901.html I haven't experimented with ng_one2many, but my understanding is that it only provides a "dumb" balancing/bonding solution. Presumably we need an ng_bonding or something along those lines would be required to achieve parity with what Linux can provide...? --Antony
