Hi Syed,
All value up to 2^32-1 are supported. In Java, the values will become
negative above 2^31, but that has to be handled by your code.
The string conversion should work as expected and also the OID.compareTo
will work correctly.
Best regards,
Frank

Hi Frank,
Would snmp4j support issuing snmp get requests where one of the terms in the
OID is larger than a signed 32-bit integer? From looking at the
org.snmp4j.smi.OID class, each term in the OID has to fit into a primitive int
supports only an array of int's.
If I had an ObjectID like 1.3.6.1.4.1.9.9.42.1.3.5.1.8.71105. 2447483647, would
snmp4j support querying such an object ?
Note that the value 2447483647 is greater than the signed 32-bit maximum
integer which is 2147483647.
If this is not currently supported, are there plans to support this in a future
version of snmp4j?
This occurs in the case of Cisco devices while monitoring response path tests where the
Cisco agent actually uses the sysUpTime from the device to keep running
"buckets" in which to store data within a given table. We first perform
getNext's to identify the 'current bucket'. Then we use that bucket as part of creating
the OID, and issue GET requests using this OID. The current bucket is increased every
hour, so that new data can be stored, and old data can be purged, and hence sysUpTime is
used to generate the bucket. Since the value of sysUpTime is an unsigned integer (or in
TimeTicks), it can actually exceed 2,147,483,647 - it's theoretical max limit is
4,294,967,294. So we notice this problem show up on devices that have been running for
greater than ~250 days.
Thanks,
Syed F. Ali
