Add a Network Cleanup Task

You can add a network cleanup task to clean up the network automatically. Automating this process saves time, especially in large networks.

To add a network cleanup task:

Select Administration > Task Scheduler.
The Task Scheduler page appears.
Click the + (Add) icon.

The Add Task page (wizard) appears.
Configure the fields in each step of the wizard according to the guidelines provided in Table 1.
Click Next to go to the next step.

Note:
Fields marked with an asterisk (*) are mandatory.
After you complete each step in the wizard, click Finish.
A confirmation message appears on top of the page, indicating that the task is added successfully.
The details of this task are displayed on the Task Scheduler page.

You can view the post-cleanup topology on the Topology page (Network > Topology). To ensure that you have the latest topology, right-click the blank space in the topology map and select Reload Network. The latest topology is displayed in the topology map.
