Using Detailed Logging to Debug SNMP Issues (149421)

MORE INFORMATION

Use the following steps to log detailed debug information to a log file (Snmpdbg.log) in the %SYSTEMROOT%\SYSTEM32 subdirectory, or to the system event log.

1. Change to the %SYSTEMROOT\SYSTEM32 subdirectory.
2. Rename the Snmp.exe file in your %SYSTEMROOT\SYSTEM32 subdirectory to SNMP.FRE.
3. Copy the checked Snmp.exe file to your %SYSTEMROOT\SYSTEM32 subdirectory.
4. From a command prompt, type the following:
   
   NET START SNMP /loglevel:20 /logtype:7
   
   Debug information will be written to %SYSTEMROOT%\SYSTEM32\SNMPDBG.LOG, and to the system event log.
5. You can adjust the output detail by lowering the /loglevel and /logtype options to lower numbers. The command uses the following syntax, where type determines where the log is created:

   net start snmp [/logtype:type] [/loglevel:level]

   The possible values are 2 for file, 4 for eventlog, and 6 for both. The default is 4. The file option creates a file under \%SYSTEMROOT%\SYSTEM32 called SNMPDBG.LOG. A value of 8 shows the output in a DebugView window. The /LOGLEVEL:level switch determines the debug level. The higher the number, the more the detail obtained. The default is 1 (minimum), and the range is from 1 to 20.
