I think it would not be able to do it, since both links are not the same speed. But please correct me. I think I am right, but I may not be. It is like when you want to do trunking on switches, that means, combine 2 or more ports on a switch to get more bw available. If the ports were not of the same speed, that would not be possible to achieve. And of course, all the ports must be full duplex. The technique is to send out data on a port at a time, in a known sequence. If ports are not the same speed, data on "x" port would arrive first than data on "y" port, being imposible to rearrenge packets on the other end, is it clear? And why being full duplex? Well, for the same reason. If ports are not full duplex, then if you sent out data on port "x" but suddenly you are receiving data on port "y", what you had to send on port "y" will have to wait. But in that time, data is travelling across link "x", and data sent out on port "x" will arrive without their "parent" data which had to be sent thru port "y". Concluding, when data sent on port "x" arrives to the other end, data that had to be sent on port "y" will have not arrived yet. I hope I was clear. lucas -- ___ /\ \ __ __ _______ _____ _____ \ \ \ /\ \ /\ \ / _____\ / ____ \ /\ ___\ \ \ \_____\ \ \\_| \\ \____/_ /\ __ \\ \ ____ \ \ \_______\\ \______ / \ ______\\ \__\_/\__\\//\_____\ \/_______/ \/_____ / \/______/ \/__/ \/__/ \/_____/
