config authen_login
Purpose Used to configure a user-defined or default method list of authentication
methods for user login.
Syntax
config authen_login [default | method_list_name <string 15>]
method {tacacs | xtacacs | tacacs+ | radius | server_group <string
15> | local | none}
This command will configure a user-defined or default method list of
authentication methods for users logging on to the Switch. The
sequence of methods implemented in this command will affect the
authentication result. For example, if a user enters a sequence of
methods like 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 methods 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 implement the enable admin
command, followed by a previously configured password. (See the
enable admin part of this section for more detailed information,
concerning the enable admin command.)
Description
Parameters
default – The default method list for access authentication, as defined
by the user. The user may choose one or a combination of up to four (4)
of the following authentication methods:
tacacs – Adding this parameter will require the user to be
authenticated using the TACACS protocol from the remote
TACACS server hosts of the TACACS server group list.
xtacacs – Adding this parameter will require the user to be
authenticated using the XTACACS protocol from the remote
XTACACS server hosts of the XTACACS server group list.
tacacs+ – Adding this parameter will require the user to be
authenticated using the TACACS+ protocol from the remote
TACACS+ server hosts of the TACACS+ server group list.
radius - Adding this parameter will require the user to be
authenticated using the RADIUS protocol from the RADIUS
server listed in the server group list.
server_group <string 15> - Adding this parameter will require
the user to be authenticated using a user-defined server group
previously configured on the Switch.
local - Adding this parameter will require the user to be
authenticated using the local user account database on the
Switch.
none – Adding this parameter will require no authentication to
access the Switch.
