Averages. t1: 40 mbps t2: 20 mbps t3: 25 mbps t4: 15 mbps Consolidation occurs; consolidating two values into one: tt1: 30 mbps tt2: 20 mbps Now check max(t1 t2 t3 t4) and max(tt1 tt2) Using the RRAs with CF MAX: t1: 40 mbps t2: 20 mbps t3: 25 mbps t4: 15 mbps Consolidation occurs; consolidating two values into one: tt1: 40 mbps tt2: 25 mbps Now check max(t1 t2 t3 t4) and max(tt1 tt2) again. If you want rates, you're doing fine. If you want maximum values, you need to process maximum values. This subject has come up either on this list or the mrtg list, I suggest a google session. cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
