Chapter2 Configuring the Cable Modem Termination System for the First Time
Configuring the Cable Interface with the Extended Setup Facility
Configuring Global ParametersStep1 Access the host by responding to the following prompt: Enter host name [cmts]:
Step2 The enable secret password is used to protect access to privileged EXEC and configuration modes. This
password, after entered, becomes encrypted in the configuration.
Respond to this prompt: Enter enable secret [Use current secret]: aa
Next, the enable password is used when you do not specify an enable secret password, with some older
software versions, and some boot images.
Step3 Respond to this prompt: Enter enable password [rHoz]: bb
Next, use the virtual terminal password to protect access to the router over a network interface.
Step4 Respond to this prompt: Enter virtual terminal password [cc]: cc
