Using The Aaa Subsystem To Control Management Access - HP ProCurve 7000dl Series Basic Management And Configuration Manual

Configuring Passwords to Control Management Access to the Router
3. Select the Use Local User List option if you want to use the usernames
and passwords configured in this list for FTP access. (This is the default
setting.)
4. If you want to use a RADIUS or TACACS+ server to control FTP access,
then you must enable the AAA subsystem. See "Using the AAA Subsystem
to Control Management Access" on page 14-35 for instructions on config-
uring these options.
5. Click Apply.
Using the AAA Subsystem to Control Management
Access
Authentication, authorization, and accounting (AAA) is an industry standard
for controlling:
which users can access a system (authentication)
what they can do once they are granted access (authorization)
what is recorded about their activities (accounting)
The AAA subsystem on the ProCurve Secure Router currently supports
authentication using a remote RADIUS server. The ProCurve Secure Router also
supports authentication, authorization, and accounting using a remote
TACACS+ server.
When you enable the AAA subsystem, you can specify a list of authentication
methods for each type of access. If one authentication method fails, the
ProCurve Secure Router will allow the user to try another access method.
The ProCurve Secure Router has specific criteria for failure:
Line and enable passwords fail if there are no line or enable passwords
configured.
RADIUS and TACACS+ servers fail if the ProCurve Secure Router cannot
reach the server on the network.
The local user list fails if the given user is not in the database.
For example, if you configure the authentication methods with RADIUS as the
first option and the RADIUS server goes down, the AAA subsystem tries the
next authentication method you configured. If you listed the local user list
after the RADIUS server, the AAA subsystem will use that authentication
method next.
