Local account user authentication
This method of user authentication employs the use of a user ID and password
and is the default method on the OPTera Metro 3000 series platforms. Local
account user authentication is the method that has been implemented in all past
releases of OPTera Metro 3000. A userID and password is managed
individually at each network element and network processor.
Note 1: This method of user authentication is not available for network
elements enabled with Centralized Security Administration (CSA) (see
Centralized Security Administration (CSA) on page 2-124) but for which
the alternative authentication method is provisioned as challenge-response.
Note 2: This is the default authentication mode for network elements.
For more information about local accounts, see Security and administration on
page 2-122.
