John,
Neither src mac (default on most platforms), dest mac, src-dest mac, src
IP or dest IP will provide you any load-balancing (from one side to the
other) here - as you only have the 2 hosts. None of your traffic
between these 2 hosts will change any of the options above unless you
configure multiple IP addresses on your hosts and use scr/dest ip. This
case would require that you separate your traffic by streams (layer 4
port numbers) if possible, but only Sup32s and 720s allow this that I am
aware of.
Here is a good link which breaks down your capabilities by platform:
http://www.cisco.com/warp/public/473/4.html#catalyst
You may still receive a small amount of "load balancing" between these 2
switches - but it would be pure luck. If traffic from HOST A takes port
13 to host B - there is a possibility that HOST B will take port 14 to
get back. You can determine which link a switch is using with the
command below:
test etherchannel load-balance interface port-channel 1 ip src-ip
dest-ip
test etherchannel load-balance interface port-channel 1 mac src-mac
dest-mac
HTH,
Daniel

Subject: The most efficient Etherchannel load balancing
Folks,
I have the following two scenarios and I want to know the most efficient
load balancing method:
HOST A--------3570-0/13----------------0/13--3550--------HOST B
-0/14----------------0/14-
HOST A--------3570--0/13----------------0/13-3570--------HOST B
-0/14----------------0/14-
As you can guess, HOST A and HOST B are fixed, there will be no more
than one host on each side, now both of the hosts are one the same vlan.
