That's not the meaning of absolute, it is most likely a gauge. Absolute resets the counter to zero after polling. It is displayed as a rate after dividing by 300 (or whatever the polling interval is). There is no counter rollover taken into account. Counter assumes a continuously monotonically increasing value with roll-overs. It is expressed as a rate. Gauge is a snapshot of data that should be displayed as is and not considered as a rate. -- Daniel J McDonald, CCIE # 2495, CISSP # 78281 > > 2012/6/9 Steve Shipway <[email protected]>: >> Possibly you should be using the 'gauge' option?
