wfAcctDataBitmask 1.3.6.1.4.1.18.3.3.2.23.2.4.1.6

Indicates which statistics were collected for this data entry, and whether there were any changes in the state of the interface since the last update interval expiration. Current bit definitions are: bit 31 bit 0 +--------------------------------+ | | +--------------------------------+ bit0 - wfAcctInBelowCirOctets bit1 - wfAcctInAboveCirOctets bit2 - wfAcctInAboveBrOctets bit3 - wfAcctInBelowCirPkts bit4 - wfAcctInAboveCirPkts bit5 - wfAcctInAboveBrPkts bit6 - wfAcctOutOctets bit7 - wfAcctOutPkts bits8-29 - reserved for future use bit30 - Interface is currently down bit31 - Interface is up, but was down during the current interval Bits 30 and 31 are intended to give an indication as to the current state of the interface and whether the interface state changed during the current interval. If bit 30 is set, the interface was down when statistics were requested, therefore all counter fields will be set to zero. If bit 31 is set, the interface was up when statistics were requested, however the state of the interface transitioned from down to up at some point during the interval, therefore statistics may have been lost.
