DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch
the Switch, the Switch will ask the first Authentication Server Hosts for authentication. If no
authentication is made, the second server host in the list will be queried, and so on. The built-in
Authentication Server Groups can only have hosts that are running the specified protocol. For
example, the TACACS Authentication Server Groups can only have TACACS Authentication Server
Hosts.
The administrator for the Switch may set up six different authentication techniques per user-defined
method list (TACACS/XTACACS/TACACS+/RADIUS/local/none) for authentication. These techniques
will be listed in an order preferable, and defined by the user for normal user authentication on
the Switch, and may contain up to eight authentication techniques. When a user attempts to access the
Switch, the Switch will select the first technique listed for authentication. If the first technique goes
through its Authentication Server Hosts and no authentication is returned, the Switch will then go to
the next technique listed in the server group for authentication, until the authentication has been
verified or denied, or the list is exhausted.
Please note that users granted access to the Switch will be granted normal user privileges on the
Switch. To gain access to administrator level privileges, the user must access the Enable Admin
window and then enter a password, which was previously configured by the administrator of the
Switch.
NOTE: TACACS, XTACACS and TACACS+ are separate entities and are
not compatible. The Switch and the server must be configured exactly the
same, using the same protocol. (For example, if the Switch is set up for
TACACS authentication, so must be the host server.)
