Hi Amit,

If your queue 1 has all the default parameters, that means your CIR=0 and PIR=max and CBS/MBS are 10ms of the CIR/PIR respectively.

I want to know if we don't configure any rate parameter nor CIR for a service lets say VPRN service , What will be my default CBS and MBS.??

>From below output i want to know that Port 2/1/10 has a total buffer pool of 12288KB out of which Reserve is 4096 (Is this max reserved for CBS) and shared is 8192KB ( Is this max MBS for this Port).

Is the below Queue 1 is sharing 1280KB from shared pool (8192) ?? means there is space for more queues to take shared reservation.
