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.
Select the authentication, or authentication sequence required:
User authentication is performed only locally by the switch..
User authentication is performed using a RADIUS server only.
User authentication is performed using a TACACS+ server only.
User authentication is performed by up to three authentication methods in the indicated sequence.
