a ESX4 server connect to two 5424 switch via 1 cable each. EQL have two connection to each 5424 switch.
the switch do not have any configuration, just power on to connect.

There is already some production vm guest running on it. I want to make use of MPIO and optimize the switch setting. I already enable MPIO on ESX side. Now I need configure the switch.

Please advise on the step-by-step of LAG configuration, and whether I can do it without interruption to my vm guests.

Thanks.
