Reestablishing DOCSIS-Compliant Bridging

To erase the current non-default cable access router configuration and return the unit to its factory default DOCSIS-compliant bridging configuration, perform the following task from privileged EXEC mode:

Step	Command	Purpose
1	uBR924#erase startup config	Erase the current configuration (assuming the current
		running configuration has been saved to NVRAM).

After entering this command, perform a warm reset of the Cisco uBR900 series cable access router by pressing and holding down the Reset button for less than 10 seconds. For information on the location and operation of the Reset button, refer to the “Physical Description” section in the chapter “Installing the Cisco uBR924 Cable Access Router” in the Cisco uBR924 Cable Access Router Installation and Configuration Guide.

Verifying DOCSIS-Compliant Bridging

To verify that the cable access router is configured for DOCSIS-compliant bridging, enter the show startup-configcommand from privileged EXEC mode. The configuration should look like this:
