Instead, the router's settings will return to the previous configuration. If remote configuration is disabled, settings you make and save at the local site do not remain in effect after the cable access router is powered off and on. Additional configuration steps might be needed, however, to support additional features, such as IPSec encryption-this additional configuration is described in the other chapters in this guide.Ĭaution Before attempting to reconfigure the cable access router at a subscriber site, contact your provisioning or billing system administrator to ensure remote configuration is allowed. The information described in this chapter applies to every cable access router that is used in a DOCSIS-compliant network.
