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 Add.
The Create New 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 steps 1, 2, and 3 in the wizard, click Submit.
The details of the task that you added are displayed on the Task Scheduler page.

After the task is completed, select the task in the list to view the results in the Summary, Status, and History tabs.

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.
