This example is from the MIB browser (TCPIP$SNMP_REQUEST.EXE).

Under certain conditions, a subagent makes a duplicate entry in
when it restarts. For example:
1.3.6.1.2.1.1.9.1.2.1 = 1.3.6.1.4.1.36.15.3.3.1.1
1.3.6.1.2.1.1.9.1.2.2 = 1.3.6.1.4.1.36.15.3.3.1.2
1.3.6.1.2.1.1.9.1.2.1 = Base o/s agent (OS_MIBS) capabilities
1.3.6.1.2.1.1.9.1.2.2 = Base o/s agent (OS_MIBS) capabilities
1.3.6.1.2.1.1.9.1.4.1 = 3256 = 0 d 0:0:32
1.3.6.1.2.1.1.9.1.4.2 = 3256 = 0 d 0:0:32
In this example, the TCPIP$OS_MIBS subagent made two entries with
different ID numbers (OIDs with the prefix 1.3.6.1.2.1.1.9.1.2) that may

sysORUpTime
translates the value received (in hundredths of a second) to the following,
dropping any fractions of seconds:
d n hh:mm:ss
In this format, n represents the number of days, hh represents the number of
hours, mm represents the number of minutes, and ss represents the number
of seconds.
The HR_MIB subagent has not yet successfully started and registered its
capabilities. If it starts, its entries in this example would use the next
available index number.
