Configuring the Switch
• All
• Telnet
• Secure Telnet (SSH)
• HTTP
Management access to different management methods may differ between user
groups. For example, User Group 1 can access the switch module only via an
HTTPS session, while User Group 2 can access the switch module via both HTTPS
and Telnet sessions. The Access Profiles Page contains the currently configured
access profiles and their activity status.
Assigning an access profile to an interface denies access via other interfaces. If an
access profile is assigned to any interface, the device can be accessed by all
interfaces.
Use the Authentication Settings menu to restrict management access based on
specified user names and passwords. You can manually configure access rights on
the switch, or you can use a remote access authentication server based on RADIUS
or TACACS+ protocols.
Remote Authentication Dial-in User Service (RADIUS) and Terminal Access
Controller Access Control System Plus (TACACS+) are logon authentication
protocols that use software running on a central server to control access to
RADIUS-aware or TACACS- aware devices on the network. An authentication
server contains a database of multiple user name/password pairs with associated
privilege levels for each user that requires management access to the switch.
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.
Ensure the following when configuring Authentication Profiles:
• 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 and the corresponding parameters for
the remote authentication protocol. Local and remote logon authentication control
management access via the console port, web browser, or Telnet.
• RADIUS and TACACS+ logon authentication assign a specific privilege level for
each user name/password pair. The user name, password, and privilege level
must be configured on the authentication server.
