Dell Networking N1500/N2000/N3000/N4000 Series Switches
Dell Networking switches support authentication of network users and switch
administrators via a number of methods. Management access to the switch is
via telnet, HTTP, SSH, or the serial console (SNMP access is discussed in the
SNMP Commands section). To ensure that only authorized users can access
or change the configuration of the switch, the administrator can require that
administrative access be authenticated.
Administrative Authentication
Switch administrators can be authenticated based on:
•Login mode
• Switch access method
• Access to Privileged Exec mode
• Two levels of access:
–1 = Read-only
– 15 = Read-Write
The supported authentication methods for switch management access are:
• Local: The user's locally stored ID and password are used for
authentication.
• RADIUS: The user's ID and password are authenticated using the
RADIUS server.
• TACACS+: The user's ID and password are authenticated using the
TACACS+ server.
• None: No authentication is used.
• Enable: Uses the enable password for authentication.
• Line: Uses the line password for authentication.
• Authentication Preference Lists (APLs): An Authentication Preference List
is an ordered list of authentication methods.
