3. Define a method name for each service to which you want to apply
accounting or authorization and specify the RADIUS or TACACS+ server
groups to use.
4.
Apply the method names to port or line interfaces.
N OTE :
This guide assumes that RADIUS and TACACS+ servers have already
been configured to support AAA. The configuration of RADIUS and
TACACS+ server software is beyond the scope of this guide, refer to the
documentation provided with the RADIUS or TACACS+ server software.

A UTHENTICATION
Use the Security > AAA > System Authentication page to specify local or
remote authentication. Local authentication restricts management access
based on user names and passwords manually configured on the switch.
Remote authentication uses a remote access authentication server based
on RADIUS or TACACS+ protocols to verify management access.
CLI R EFERENCES
◆ "Authentication Sequence" on page 866
C OMMAND U SAGE
◆ By default, management access is always checked against the
authentication database stored on the local switch. If a remote
authentication server is used, you must specify the authentication
sequence. Then specify the corresponding parameters for the remote
authentication protocol using the Security > AAA > Server page. Local
and remote logon authentication control management access via the
console port, web browser, or Telnet.
◆ You can specify up to three authentication methods for any user to
indicate the authentication sequence. For example, if you select (1)
RADIUS, (2) TACACS and (3) Local, the user name and password on
the RADIUS server is verified first. If the RADIUS server is not
available, then authentication is attempted using the TACACS+ server,
and finally the local user name and password is checked.
P ARAMETERS

◆ Authentication Sequence – Select the authentication, or
authentication sequence required:
■
Local – User authentication is performed only locally by the switch.
■
