The title speaks for itself. I have never attempted this but understand there is a way to use two network cards (en0 and en1) with the same IP address so as to load balance the traffic flow through both cards. Anyone know the answer?

Hi ,
You can create one etherchannel across two or more network card . If you're switch support this kind of connection .

from smitty commodev => etherchannel => add an etherchannel , choose the first and in the "backup adapter field , put the other . After , you can normally configure ip , netmask and .... by configuring the new adapter .
look with "lsdev -Ccadapter" for the new one .

Thanks for the information. I knew there was a way to doit. Again many thanks.

Can you do this if one card is on a Class a network and another on a Class C network, if both with the same gateway?

neither card should be configured for IP when you create the etherchannel device - it will not work if they were.
you then configure the IP on the etherchannel device.

Some light reading for you:
