I've been successfully using a large number of vlans over bce1,em0 and em1 with iSCSI, but wanted to switch to AoE(ata over ethernet). I've set vlandevs by round-robin, and got vlan1 on bce0, vlan2 on em0, vlan3 on em1, vlan4 on bce0....vlan12 on em1. I've binded net/vblade instances to each interface, but the problem I'm facing now is that while vlans 1-10 are working properly, vlans 11 and 12 won't see any traffic unless the interface is in promiscuous mode. I noticed that while trying to attach tcpdump and saw the thing instantly work. I've had no problems with iSCSI over the same setup, and dhcp packets are getting trough properly. I've moved those last two vlans to bce0 and they work ok, but I'm a bit locked on why this is happening. Are there any known limitations on vlans on e1000?
