Usage Guidelines

It is normally not necessary to enter this command in data-over-cable bridging applications because 
DOCSIS-compliant bridging is enabled by default. If you wish to do full transparent bridging rather 
than DOCSIS-compliant bridging, use the no form of the command, then configure full transparent 
bridging using CLI commands. See the “Configuring Bridging” section on page 41 for instructions.

Examples

The following example shows how to enter the cable-modem compliant bridge command for a 
cable access router interface, starting from global configuration mode:

uBR924(config)# interface cable-modem 0

uBR924(config-if)# cable-modem compliant bridge

uBR924(config-if)#
