Hello GS,

I am new to GS. I have been reading every post since June but this is my first contribution.

Can someone let me know if my understanding of the implementations of ECN are correct?

Global config command "ip tcp ecn" enables ECN for all tcp traffic transiting the router while "random-detect ecn" in a policy map only affects tcp traffic matched in a policy-map and applied with the service-policy interface command.

They have the exact same affects on traffic but one is more selective than the other - is that right?

thanks
Bruno
