3 port lag question.
We have 3 of those swit hes in a stack. I have a lag set up using 1/0/11, 2/0/11, 3/0/11 at switching > lag configuration 2 ports are active and lag state is UP the target switch is a M4...
Ok, I known your concern.
Could you please change port-channel load-balance to default 3, and try again?

Hi robfantini,
As we see the port 3/0/11 status is 'Detach', I think maybe the unit 3 can't working normaly, right?
So please execute CLI command as below:
1. show switch
2. show stack-port
3. show port all
I got 'Message cannot exceed 20,000 characters' so for last command i removed a lot of what I whink were unnecessary lines.
