If a user no longer needs access to manage Lumen® Secure Access Mobility and Lumen® Managed Network Services CLI (command-line interface), you can delete their user information from Control Center.
Control Center lists the Radius users for your organization. If you have more than one customer number or billing account number, use the lists to select the customer number and billing account number you want to view Radius users for. Once you select the customer number and billing account number, use the Domain list to select the domain you want to view users for (if you have more than one domain).
On the row for the user your want to delete, click Delete User.
In the confirmation windows that appear, click Delete, then click OK.
