Hi gurus

I'm using cisco 4006 and need to know what "port-channel load-balance src-mac" means.

Is it,
        1. Balance the load only out of the port-channel
        2. Balance the load only in of the port-channel
        3. Balance the load only whatever direction of the port-channel as long as its pure mac
        4. Something else.

Of course, I would like to use load balancing to both directions (in and out of the port-channel), so should I use
        1. "port-channel load-balance src-dst-mac"    command
        2. port-channel load-balance src-dst-ip"      command

By the way. What is the difference between these commands.

Thanks advance

if you leave it as the default without adding any code it was load balance based on source and destination IP address, if you want to specify it the command is

port-channel load-balance -dst-ip

and if you want to load balance based on mac the config is

port-channel load-balance -dst-mac

and the difference between the two is one works at layer 2 and one works at layer 3

Thaks for your answer, but I know allready those commands.

But didn't mevtion anything about command :

port-channel load-balance src-dst-mac

What that command does ? Does it balance the load bouth direction -> inbound and outbound to/from port-channel ?

Now I use this "port-channel load-balance src-mac" -command. I think that this make louad-blance to use only one direction. Is't so? Or is it even possible to make bouth network cards work either way full speed. Now it seems to me, that when I send or receive data, first network card works fine (full sending and receiving) but second card only send OR receive data.

So how I can get bouth cards to use full 100 Mb speed at the same time ?
