cnt2XIfCounterDiscontinuityTime
Module: CNT21-MIB
OID (symbolic): CNT21-MIB::cnt2XIfCounterDiscontinuityTime
OID (numeric): 1.3.6.1.4.1.333.2.1.2.3.1.30
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: The value of sysUpTime on the most recent occasion at which any one or more of this interface's counters suffered a discontinuity. The relevant counters are the specific instances associated with this interface of any Counter32 or Counter64 object contained in the ifTable or ifXTable. If no such discontinuities have occurred since the last re-initialization of the local management subsystem, then this object contains a zero value.
What is cnt2XIfCounterDiscontinuityTime?
This TimeStamp records the sysUpTime at which any of this interface's Counter32 or Counter64 statistics, whether in the base or extended table, last experienced a discontinuity such as a reset. An administrator checks this value before trusting a simple before-and-after subtraction of any of this interface's counters, since a discontinuity invalidates that kind of naive math. For example, if cnt2XIfCounterDiscontinuityTime just updated, the admin knows a straightforward difference of two cnt2XIfInOctets readings spanning that moment would be meaningless.
Examples
Walk all instances (SNMPv2c):
