Comparing Configuration Settings of Devices

 

You can compare the configuration of a SDG with any other SDG that is discovered. You can contrast and view the configuration settings of a master device with another master device in two SDG high availability pairs, of a standby device with another standby device, or of a master and a standby device in the same SDG pair. You can compare the settings of up to four devices simultaneously. After you select the desired device and initiate the comparison operation, you can also add more devices until the maximum limit of four devices is reached for comparison.

The services are displayed and the objects or components of each service instance are also shown. You can filter and view a specified service component or the components of all services. A red minus mark denotes that the particular parameter or element is not available or configured on the specified device. A green tick mark denotes that the particular parameter is available on the corresponding device. For attributes that can contain values, the associated values are shown for the appropriate device. Otherwise, for attributes that can either be disabled or enabled, the red minus icon or green tick icon provides a graphical indication. To compare the configuration settings of two or more devices
