This does not look like to be a sysuptime OID.

[john at xwing]/home/john>: snmptranslate -Oa 1.3.6.1.2.1.25.2.3.1.6.101
HOST-RESOURCES-MIB::hrStorageUsed.101


it looks like it is used for storage, perhaps you were monitoring
storage before?? did you try snmpwalk'ing with that OID?? I get no output

[john at xwing]/home/john>: snmpwalk -c public -v 1 localhost
1.3.6.1.2.1.25.2.3.1.6.101


It just goes right back to command prompt after that.

To recap: That OID doesnt appear to be sysuptime or sysname.


Regards,

John
