That should not be the case, you can do either active or passive LACP
across stack members, with both lacp ports up and forwarding/load
balancing. Maybe you were on an older version of code? Even then I do not
recall that being a limitation.

We have 4 x 1GbE LACP trunks working between MLX's and stacks of 2 FCX's. All ports are forwarding...MLX ports are configured for active mode and FCX ports are passive mode.

You can trunk up to 8 x 1GbE in a group across members of the stack however you might like(short of between members of the same stack of course) and all should forward traffic appropriately. 10GbE lags are only supported in two port trunk groups though.

Dear Everyone,

I seem to remember that configuring an LACP trunk on the FCX across stack members resulted in the stack only being active/passive... Please correct me if I'm wrong...

Regards,
Brant.
