I am running OS X 10.5.8 and trying to set up link aggregation with two NICs to my switch. The switch has both ports "trunked" and they show as up, but as soon as I combine the NICs, I lose all connectivity to my computer. Under the status of the bonded interface, it says "wrong group" and no transmit or receive.
Both NICs are included in the bonded interface and they both function perfectly as separate interfaces. I have followed instructions on the apple website, as well as many other forums to no avail. I have tried assigning only an IP to the virtual interface, IP's to the virtual and physical, DHCP, manual IP, manual virtual interface and dhcp physical interface.
