cable modems will not be able to connect to the Internet.
Enabling conditional access
Using your browser connect to IRIS configuration interface. Select “CM Subscription” under
Advanced options.
To enable conditional access to the modems select the “Subscribe selected cable modems” and
then select “Save”. This change comes into effect after you restart IRIS.

subscribed but have tried to connect to the IRIS will show up in the “unsubscribed modems” list.
You can move cable modems that show up in the “unsubscribed modems” list to the “subscribed
