384 Observer Suite: SNMP Management
Conclusion
The complexities involved in the design and building of custom forms are considerable,
but are more than compensated for by the great amount of control that custom forms give
to both the display of SNMP information and the control of SNMP devices.
By careful form design, it is possible not only to make data more useful to experienced
Observer users, but also to make it possible for users with little technical knowledge to
interact effectively with SNMP devices.
The MIB Walker
Overview
In attempting to configure or reconfigure an SNMP device, it’s often useful to be able to
see what OID values the SNMP device has and to explore the implementation of both
standard MIBs and the SNMP device’s proprietary MIBs.
This is particularly useful when a device uses proprietary OIDs for which
there is no published MIB file or when a published MIB file has an error in it.
By rewriting (and then recompiling) a MIB file to reflect the actual
configuration, you can have more control over the device, even if it is
nonstandard.
The tool that is used to explore the MIB objects and values on a device in SNMP
Management Console is the MIB Walker.
