Researching and identifying which functions are available in SNMP are part of building a dial NMS
environment. In this case study, UCD-SNMP, an opensource freeware application that allows access to
SNMP functions from a command line interface (CLI), is used to explore the capabilities of SNMP.
There are many benefits to using UCD-SNMP.
You can:
Gain a fundamental understanding of how SNMP functions and protocols work in a dial access
environment. This knowledge provides a solid foundation for using automated and GUI-based
SNMP applications.
Learn how to use a low-level troubleshooting capability in the event that other SNMP applications
produce questionable results.
Poll any OID and verify SNMP agent responses.
Use stable and reliable CLI commands. UCD-SNMP is unobstructed by GUI functionality.
Explore and research MIB content.
Discover what functions are available to manage a Cisco IOS device.
Create customized scripts and tools.
For this case study, the dial engineers at THEnet created a tool called SNMP Commander. The tool
aided the MIB research task by enabling dial engineers to build web-based object identification (OIDs)
bookmarks, which they could go to without using a keyboard.
By using UCD-SNMP and SNMP Commander, the dial engineers at THEnet identified which items the
commercial NMS applications would monitor within the network operations center (NOC).
