Identifying MIB file problems and errors<br />

If an error exists in a MIB file, you can use the MIB manager to identify where code problems<br />

exist, then open the MIB file in a text editor (for example, Notepad) and correct the code.<br />

There are a variety of issues that may exist in the code; for example, there may be a simple<br />

syntax error in the MIB file or there could be a MIB file that has a dependency on another MIB<br />

file. Use the error messages when you view a MIB file to find and correct the problem.<br />

There are two types of errors that may display in the SNMP MIB Manager list:<br />

(Warning). This indicates a minor issue with the MIB file (for example, a small<br />

syntax problem). A MIB file that contains a warning may continue to work, but it is<br />

best to identify and correct the issue in the MIB file.<br />

(Error). This indicates there is a problem in the MIB file that prevents it from<br />

working. A MIB file that contains an error must have the error corrected in order for<br />

the MIB file to function.<br />

Tip: The most common MIB errors are caused by a MIB dependency on another MIB file that<br />

is not included in the MIB library. Often, when this issue is corrected, many of the MIB issues<br />

are resolved.<br />

Example: If a MIB is missing, the MIB Manager indicates the issue in an error as shown in this<br />

example excerpt from a MIB status report:<br />

22 ipMRouteGroup, ipMRouteSource,<br />

23 ipMRouteSourceMask, ipMRouteNextHopGroup,<br />

24 ipMRouteNextHopSource, ipMRouteNextHopSourceMask,<br />

25 ipMRouteNextHopIfIndex,<br />

26 ipMRouteNextHopAddress FROM IPMROUTE-STD-MIB<br />

Error: Cannot find module (IANA-RTPROTO-MIB): At line 26 in<br />

C:\PROGRA~1\<strong>Ipswitch</strong>\<strong>WhatsUp</strong>\Data\Mibs/IPMROUTE-STD-MIB.my<br />

The important information in this report is:<br />

Cannot find module (IANA-RTPROTO-MIB).<br />

This information indicates that the IANA-RTPROTO-MIB is missing from the MIB library in<br />

C:\Program Files\<strong>Ipswitch</strong>\<strong>WhatsUp</strong>\Data\Mibs<br />

If you determine that a MIB file is missing, you can manually copy the file to the \Program<br />

Files\<strong>Ipswitch</strong>\<strong>WhatsUp</strong>\Data\Mibs\ directory or use the SNMP MIB Manager dialog to<br />

add (import) a new MIB file.<br />
