DES-3526 / DES-3526DC Fast Ethernet Layer 2 Switch
IP Address The IP address of the remote server host the user wishes to add.
Protocol The protocol used by the server host. The user may choose one of the following:
• TACACS - Enter this parameter if the server host utilizes the TACACS
protocol.
• XTACACS - Enter this parameter if the server host utilizes the XTACACS
protocol.
• TACACS+ - Enter this parameter if the server host utilizes the TACACS+
protocol.
• RADIUS - Enter this parameter if the server host utilizes the RADIUS
protocol.
Port (1-65535) Enter a number between 1 and 65535 to define the virtual port number of the
authentication protocol on a server host. The default port number is 49 for
TACACS/XTACACS/TACACS+ servers and 1813 for RADIUS servers but the user
may set a unique port number for higher security.
Timeout (1-255) Enter the time in seconds the Switch will wait for the server host to reply to an
authentication request. The default value is 5 seconds.
Retransmit (1-255) Enter the value in the retransmit field to change how many times the device will
resend an authentication request when the TACACS server does not respond.
Key Authentication key to be shared with a configured TACACS+ or RADIUS servers only.
Specify an alphanumeric string up to 254 characters.
Click Apply to add the server host.
Login Method Lists
NOTE: More than one authentication protocol can be run on
the same physical server host but, remember that
TACACS/XTACACS/TACACS+ are separate entities and are
not compatible with each other
This command will configure a user-defined or default Login Method List of authentication techniques
for users logging on to the Switch. The sequence of techniques implemented in this command
will affect the authentication result. For example, if a user enters a sequence of techniques, for
example TACACS - XTACACS- local, the Switch will send an authentication request to the first
TACACS host in the server group. If no response comes from the server host, the Switch will send an
authentication request to the second tacacs host in the server group and so on, until the list is
exhausted. At that point, the Switch will restart the same sequence with the following protocol listed,
XTACACS. If no authentication takes place using the XTACACS list, the local account database set
in the Switch is used to authenticate the user. When the local method is used, the privilege level will
be dependant on the local account privilege configured on the Switch.
Successful login using any of these techniques will give the user a "User" privilege only. If the user
wishes to upgrade his or her status to the administrator level, the user must use the Enable Admin
window, in which the user must enter a previously configured password, set by the administrator. (See
the Enable Admin part of this section for more detailed information concerning the Enable Admin
command.)
