5.6 Using SNMP Security
NNM is an SNMP management system. It provides several services and applications that use SNMP to
communicate with devices that have SNMP agents. These services and applications include discovery, the SNMP
MIB browser, the data collector, and the application builder. NNM also provides several utilities on the menu bar
that are pre-customized SNMP applications such as "System Information".
To be able to identify SNMP managed devices during the discovery and use the various tools provided by NNM and
HP Toptools for OpenView NNM, the correct SNMP community name must be known to NNM. The default
community name ("string") used by NNM and toptools for network devices is normally "public". If devices do not
use "public" you will need to enter the configured community name for each device into NNM. To set SNMP
community strings, you may use the NNM “SNMP Configuration” application found on the NNM menu bar. For
instructions, consult your NNM documentation or online help.
Note: If an HP device, such as a Netserver, has a community configured that is not known to NNM prior
to discovery, it will not be recognized by the bridge. If the community is entered into NNM after
discovery, the Netserver will be identified following the next discovery cycle. To force a refresh,
ovstop and ovstart hpttBrdgDisc.
