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. However, to configure the router for full transparent
bridging or for routing mode, use the no form of the command and then configure the router as desired
using the appropriate CLI commands.
Examples
The following example shows how to disable DOCSIS-compliant bridging on the cable interface:
Router# configure terminal
Router(config)# interface cable-modem 0
Router(config-if)# no cable-modem compliant bridge
Router(config-if)#
OL-1581-07
cable-modem compliant bridge
no cable-modem compliant bridge
