Command Modes Interface configuration (cable interface only)
Command History
Usage Guidelines This command sets the Registration IP Address parameter in TSI messages. By default, the downstream

IP address instead of to the downstream channel IP address.

This command is available only in images that support telco-return. These images have a “t” as part of
the image name.
