does any one know what is the maximal number of entries in MIB table?
SNMP limits individual subidentifier values to the range of 0..4294967295 (2^32-1), which for a single integer-valued index would mean a fundamental limit of 4294967296 rows (a limit unlikely to be reached before memory constraints set in). Individual index objects may impose further constraints on ranges, which would further limit the number of rows, but multiple index objects would result in a multiplicative factor (e.g. two Unsigned32 indexes without further range constraints would mean a fundamental limit of 2^64 rows). SNMP also limits the number of subidentifiers in an OID value to 128, so if you really want to take the numbers to truely absurd levels you could have about 2^4000 rows with 125 Unsigned32 index objects (assuming a table were allowed to be assigned about 3 subidentifiers down from the root). Thus, in principle, there is no realistic limit other than those imposed by index object constraints, memory limitations or limitations of an individual implementation. Michael
