D-Link xStack DES-6500 User Manual - Login Method Lists

xStack DES-6500 Modular Layer 3 Chassis Ethernet Switch User Manual 

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. 

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 

Login Method Lists 

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.)
