For example, if we aggregate 4 ethernet cards into one virtual interface (fec), do this mean that the throughput is 4 times the capacity of one ethernet card ?. Also, if the pyshical interfaces are connected to different LANs, how can we think about the virtual iface ? is it as if we were joining the 4 LANs to make one common link ? is this right ? -- ****** JFRH ****** A classic is something that everybody wants to have read and nobody wants to read. -- Mark Twain
