Configuration Settings Tab Parameters

The easiest way to configure Nyquist appliances is to obtain configuration settings from the Nyquist server by selecting Get Configuration From Server. However, you can manually configure an appliance through the appliance’s Web UI when Standalone Operation is enabled (see"Standalone Operation Configuration Settings").

To manually configure your Nyquist appliance:

1    On the appliance Web UI’s main page, select Configuration Settings.

2    View the settings as described in Table 5 for normal configuration, or modify the settings as described in"Standalone Operation Configuration Settings" for Standalone Operation configuration.

3    If changes were made (Standalone Operation only), click the Save Configuration Settings and/or Save Multicast Addresses buttons to save your changes.



The following table describes the Configuration Settings tab settings when Standalone Operation is not enabled for this device:
