This is incorrect, you can load balance on IP src,dst and even layer 4 info
such as TCP/UDP src/dst port. If you have the older Sup1 with a PFC1 sub
module WS-F6020 then the only method is MAC, if PFC2 L3 engine then the
above is possible.

It seems that the Catalyst series utilizes an X-OR operation on the last two
bits on the source destination MAC address whereas the router (like 75XX)
uses the last two bits of the X-OR of the IP address

Some platforms will only loadbalance per destination MAC address. Not very
useful on router-router links.
