Configuring Local/Remote Logon Authentication

CONFIGURING LOCAL/REMOTE LOGON AUTHENTICATION
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.
COMMAND USAGE
◆ 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 a web
browser.
◆ 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.
PARAMETERS
