"where the commands is not available"
Means the 3550.... And the behavior you're seeking
"the source and destination IP address is also enable for routed IP Traffic"
Is done by DEFAULT on the 3550's... see
http://www.cisco.com/en/US/docs/switches/lan/catalyst3550/software/release/1
2.2_25_see/command/reference/cli1.html#wp1864309
port-channel load-balance {dst-mac | src-mac}
Defaults
The default is src-mac.
Usage Guidelines
When src-mac is used, load distribution based on the source and destination
IP address is also enabled. For all IP traffic being routed, the switch
chooses a port for transmission based on the source and destination IP
address. Packets between two IP hosts always use the same port for packet
transmission, but packets between any other pair of hosts might use a
different transmission port.
So with the 3550's do nothing and you get the results the question wanted...
Or for the 3560's do what question asked "balance the to traffic based on
source/destination MAC address where possible" use
Port-channel load-balance src-dst-mac

Subject: Complex Question - Need complete Answer ( SWITCHING )
Hi 2 all.
Appreicate if you experts can provide complete answer to the following
switching Question:-
sw1=============SW2 ( ports 23/24 )sw1=============SW3 ( ports 19/20
)sw1=============SW4 ( ports 21/22 )
sw2=============SW1 ( ports 23/24 )sw2=============SW3 ( ports 21/22
)sw2=============SW4 ( ports 19/20 )
sw3=============SW1 ( ports 19/20 )sw3=============SW2 ( ports 21/22
)sw3=============SW4 ( ports 23/24 )
sw4=============SW1 ( ports 21/22 )sw4=============SW2 ( ports 19/20
)sw4=============SW3 ( ports 23/24 )
<Q> Customer have made some complaints of their systems running slow at
times
between SW1 and SW2. To improve performance you decided to provide multiple
200M ports from the existing connections between all 4switches, andbalance
the
to traffic based on source/destination MAC address where possible, where the
commands is not available choose a method of balancing where the source and
destinationIP address is also enable for routed IP Traffic.
