The "vif create e4a e4b e4c efd" command will create a vif that encompasses all 4 of the network interfaces. This simply creates the vif. Then you must ifconfig the vif# just like you would any other network interface. The new vif# is now your network interface and not e4a e4b e4c and e4d they all make up the one vif.
actually the syntax is "vif create <trunkname> <components>" in the old releases. The new release adds another option between "create" and "trunkname." Now a trunk could be "multi" or "single," where single means that only one interface in the trunk will be used at a time and multi means that the load will be potentially spread over all interfaces in the trunk. The "single" version of trunking provides multipathing, so if one of your switches dies you can go through a different one.
Now for the kicker:
Does anyone know how to successfully configure a trunk (multi) to take over as a partner interface? "ifconfig <trunkname> [optional blah blah blah] partner <partner's ip>" does not work (at least for me ) in 5.3.2.R1. It returns an error about invalid partner. I can provide more detail, just not at the moment.
