Configuring MAC Interface Parameters
MAC interface parameters are described in the following sections.
Shared Secret
The Shared Secret parameter is the authentication string shared between the
CMTS and the provisioning server. The shared secret is used by the CMTS to
validate that a cable modem was provisioned by an authorized server. If this
parameter is left blank, the CMTS does not validate a modem’s provisioning.
Note that the same value must be configured on the provisioning server.
Configuring no shared secret turns off authentication of modem
provisioning.
