hello i have two cisco l2 switch
i set same load balancing algorithm in two switch
i send same traffic to two switch
its out from port 0 switch 1
and out from port 5 switch 2
how to config two switch to get same output from all device
can help me?

Hello @hdihd9162 ,
to avoid polarization load balancing uses an hash with a seed that is chosen at boot time and that is different on each device.
So what you see is to be considered normal
Hope to help

Exactly what I too suspected, but platform not named. I recall (?) on some large Catalysts (6500s?), there was a configuration setting for different polarization algorithms.
Don't know for sure, but on old/ancient low end Catalysts they might have always polarized but newer Catalysts might always use a seed value.

Oh, for those unfamiliar with polarization. . .

i need it same i looking for awnser

It must be same PO if the hash same'
Try use in both SW
show platform software fed switch active etherchannel 1 load- balance mac <src mac> <dst mac>
Check the selection port
