Debasis The short answer to your question is that the locking counters are there only because that was how the original DECNet specification is written. They are only required for those implementations of the MIB which do not support the more standard SNMP based counters (DEC products are about the only ones that come to mind right away). SNMP based counters (from RFC1155), rather than latching at maxvalue (e.g. 65535) are: "...a non-negative integer which monotonically increases until it reaches a maximum value, when it wraps around and starts increasing again from zero. This memo specifies a maximum value of 2^32-1 ...... for counters" The counters which can be zerod in the MIB are those which correspond to the objects which could be zerod in DECs original specifications - that really was the reason for including this feature. For many of groups which have counters you will see seconds since last zero'd - useful if you see counters at max value with what appear to be reasonably short time spans since seconds since last zerod. /jon
