In the upper-right corner, click the down arrow next to your enterprise ID, then click the Enterprises link.
Control Center lists the enterprise IDs your user profile is currently assigned to and the default portal for that enterprise ID. If you already have a default enterprise ID selected, Control Center lists it in the My Default Enterprise section. In the example shown below, there is no default enterprise ID.
On the left side of the row for the enterprise ID you want to set the default portal used for, click the blue down arrow ().
From the Portal Default list, select the portal you want to use for the enterprise ID.
If you also want to set the enterprise ID to be the default enterprise you view when you log in, click Set As My Default Enterprise.
Note: You can only use Control Center to view enterprise IDs containing former CenturyLink services. You can select Control Center to view enterprise IDs containing former Level 3 services, but you won't see any data until the portals are fully integrated.
