2.2.4 Configuring communication protocols

NNMi uses SNMP and ICMP (ping) to discover and monitor devices, and receives SNMP traps (notifications of problems).

Before you begin

Devices are classified into SNMP devices that respond to SNMP and non-SNMP devices that do not respond to SNMP.

[Figure]

In the following procedure, you can configure the behavior of communication protocols SNMP and ICMP (ping) that NNMi uses to discover and monitor networks. In the procedure, the settings below are used as an example. Change the setting values as necessary.

Settings for the timeout and the number of retries for SNMP and ICMP: Default (do not change)
SNMP Minimum Security Level: Default (do not change)
Read Community Strings: public

Procedure

In the Configuration workspace, select Communication Configuration.
In the Default SNMPv1/v2 Community Strings tab, click (New).
Enter the value in Read Community Strings, and then click (Save and Close).
Example: Read Community Strings: public

If a network to be monitored uses multiple community strings, repeat steps 2 and 3 to specify those community strings. NNMi checks the community strings configured in the network in parallel, and uses the appropriate value.
In the Communication Configuration view, make sure that the configured settings are displayed, and then click (Save and Close).
The configured settings are saved.

Next steps

You have now successfully configured the communication protocols. Next, you will perform network discovery in the network to be monitored.
