Overview
You can perform user authentication with either the SuperStack II Remote
Access System (RAS) 1500 local authentication facility, Remote
Authentication Dial-In User Service (RADIUS) authentication, network
operating system (NOS) authentication, or local authentication and either
RADIUS or NOS. The following list describes each option:
■
Local authentication only — The RAS 1500 grants or denies access
based on information in the local user table only.
■
RADIUS authentication only — The RAS 1500 sends a request to
the RADIUS server and grants or denies access based on the response.
■
NOS authentication only — The RAS 1500 sends a request to the
NOS authentication server and grants or denies access based on the
response.
■
Local authentication and either RADIUS or NOS
authentication
— The RAS 1500 first checks the local user table. If
the user is defined in the local user table, the RAS 1500 grants or
denies the user access based on information in the table. If the user is
not defined in the user table, the RAS 1500 sends a request to the
RADIUS or NOS authentication server and grants or denies access
based on the response.
