Usage Guidelines
To verify whether or not upstream differential encoding is activated, enter the show running-config
command and look for the cable interface configuration information. If upstream differential encoding
is enabled, a differential encoding entry is displayed in the output of the show running-config
command. If upstream differential encoding is disabled, no differential encoding entry is displayed in
the output.
If you are having trouble, make sure that the cable connections are not loose or disconnected; the cable
interface line card is firmly seated in its chassis slot; the captive installation screws are tight; you have
entered the correct slot and port numbers; and you selected a valid frequency for your router.
Examples
The following example shows how to enable differential encoding for upstream port 2:
Router(config-if)# cable upstream 2 differential-encoding
