1.On the target map page, right-click on the blank area and select Compare. The Compare action node is expanded in a runbook.
By default, the Compare Same Device option is selected.

2.In the Compare pane, click the icon next to the Compare Same Device option, and select the Compare Two Devices option.

3.In the two Dataset fields, specify the data source for comparison. There are three types of data sources:

▪Current  Baseline — Use the latest device data saved in the database directly.

▪Historical Data — Use the latest successful device data retrieved during the specified historical time period. For example, there are two benchmark tasks over a specified time, and task1 was executed earlier than task2. Task1 successfully retrieved device configuration and ARP but did not get MAC table, while task2 successfully retrieved ARP/MAC table but did not get the configuration, then the system will use the configuration retrieved in task1 and ARP/MAC table retrieved in task2 as the data source.

▪Default Live — Log into the device instantly to retrieve live data.

4.In the Device field, specify two target devices.

Note: Device2 is used as a reference only, and Device 1 is the main body to compare with it.

5.Select the data types that you want to compare, and then click Compare.

Tip: You can click Route Table Settings to customize route attributes for comparison for the Route Table data type. For example, If you only select the AD and Metric fields besides the built-in two attributes (destination address and Mask), two routing entries will be considered equal only if they have the same destination, subnet mask, administrative distance, and metric.

6.In the comparison result, select a data type to view change details. See Browsing Comparison Results for more details.
