To reset the default synchronization message interval, use the no cable sync-interval
command in Interface Configuration mode, as shown below:
MOT(config-if)#no cable sync-interval {1-200}
Setting CM Authentication Parameters
The default authentication parameters are enabled, but have a null value by default.
Set authentication parameters on the cable interface and the CMs to ensure security on
the HFC network.
1. Use one the following two options to configure CM authentication parameters so
that all CMs return a known text string to register with the cable interface for
network access
:
• If you want to activate CM authentication so that all CMs return an
unencrypted text string to register with the cable interface for network access,
use the cable shared-secret 0 command in Global Configuration mode, as
shown below:
MOT(config)#cable shared-secret 0 <“authentication string”>
where:
0 specifies that an unencrypted authentication text string follows.
“authentication string” is an alphanumeric text string specified in double
quotation marks.
Caution: Ensure that the authentication string or hexadecimal key in the CM
configuration file matches the authentication string or hexadecimal key
configured on the cable interface. CMs cannot register with the cable
interface if the authentication parameters do not match.
Note: The "authentication string" on the BSR can be up to 253 characters.
