2. To verify that CM authentication is deactivated, use the show running-config
command in Privileged EXEC mode and view the cable interface
configuration information. The output will show if CM authentication is
deactivated.
RDN#show running-config
3. To enter Interface Configuration mode from Global Configuration mode to
configure the cable interface, use the interface cable command, as shown in
the following example:
BSR64000(config)#interface cable {<slot number>/<interface number>}
where:
slot number refers to the DOCSIS module slot number on the BSR 64000
interface number refers to the cable interface
4. The default authentication parameters are enabled, but have a null value by
default. Authentication parameters need to be set on the CMTS and the CMs
to ensure security on the HFC network. To activate authentication on the
CMTS so all CMs return a known text string to register with the CMTS for
network access, use the cable shared-secret command in Interface
Configuration mode, as shown in the following example:
RDN(config-if)#cable shared-secret [n] [<“authentication string”> |
<0xkey>]
where:
n is the number of the shared secret
Note: The BSR 1000 uses the same syntax as the above command,
however both the slot number and interface number are set to zero.
Caution: Ensure that the authentication string or hexadecimal key in the
CM configuration file matches the authentication string or hexadecimal
key configured on the CMTS. CMs cannot register with the CMTS if
authentication parameters do not match.
