Tom,please do not talk about a counter 'reset' or resetting a counter to zero. This is not how SNMP counters work. Instead, make it clear for every Counter what the discontinuity indicator is. See Section 7.1.6 of RFC 2578: Counters have no defined "initial" value, and thus, a single value of a Counter has (in general) no information content. Discontinuities in the monotonically increasing value normally occur at re- initialization of the management system, and at other times as specified in the description of an object-type using this ASN.1 type. If such other times can occur, for example, the creation of an object instance at times other than re-initialization, then a corresponding object should be defined, with an appropriate SYNTAX clause, to indicate the last discontinuity. Examples of appropriate SYNTAX clause include: TimeStamp (a textual convention defined in [3]), DateAndTime (another textual convention from [3]) or TimeTicks. The default discontinuity indicator is sysUpTime. If NAT instances can come and go dynamically, you want to specify other discontinuity indicators. /js
