Chapter 2 Cisco CMTS Configuration Commands
cable shared-secret
Router#
Note
In this example, the shared-secret string is initially entered as clear text, but because the
service
password-encryption
command has been used, the string is encrypted in the configuration file.
The following example shows how to remove the use of a shared-secret encryption key on a cable
interface. That particular interface then ignores any shared-secret that is used when calculating the MD5
checksum:
Router#
config t
Router(config)#
int c6/0
Router(config-if)#
no cable shared-secret
Router(config-if)#
end
Router#
