Hi, There were a bunch of changes to RELENG_8's em driver a week ago. Perhaps update to that first. But what sort of em nics do you have ? pciconf -lvc will show it. I have a number of boxes with 20 or more ifconfig | grep ^vlan | wc 20 120 1562 Most of which are pcie based, or onboard 82574L types. ---Mike > 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).
