Enabling the Subscriber and Subscription Configuration on the C-Web Interface
Before you can configure subscribers and subscriptions with the C-Web interface, you must enable the policy, service, and subscriber editor on the C-Web interface. To do so :
If you are using multiple C-series Controllers, we recommend that you enable the policy, service, and subscriber editor on only one C-series Controller on your network.
CAUTION: If you enable the editor on multiple platforms, there is a risk that configuration changes will conflict. In this case, the second edit that is committed to the platform is lost.
