Which statement is true about the show running-config output?
A.
Sw2 is configured for switch-based authentication using RADIUS.
B.
Interface FastEthernet0/6 is configured with a SmartPort macro using RADIUS.
C.
Interface FastEthernet0/6 is configured for 802.1X Authenticated Trunking Protocol (ATP).
D.
Interface FastEthernet0/6 is configured for port-based traffic control.
E.
Interface FastEthernet0/6 is configured for port-based authentication.
Explanation:
Enabling 802.1X Authentication
To enable 802.1X port-based authentication, you must enable AAA and specify the authentication
method list. A method list describes the sequence and authentication methods to be queried to
authenticate a user.
The software uses the first method listed to authenticate users; if that method fails to respond, the
software selects the next authentication method in the method list. This process continues until
there is successful communication with a listed authentication method or until all defined methods
are exhausted. If authentication fails at any point in this cycle, the authentication process stops,
and no other authentication methods are attempted.
Beginning in privileged EXEC mode, follow these steps to configure 802.1X port-based
authentication. This procedure is required.
Command
Purpose
Step 1
configure terminal
Enter global configuration mode.
Step 2
aaa new-model
Enable AAA.
Step 3
aaa authentication dot1x {default}method1[method2…]
Create an 802.1X authentication method list.
To create a default list that is used when a named list is not specified in theauthentication
command, use the default keyword followed by the methods that are to be used in default
situations. The default method list is automatically applied to all interfaces.
Enter at least one of these keywords:
•
group radius—Use the list of all RADIUS servers for authentication.
•
none—Use no authentication. The client is automatically authenticated by the switch without using
the information supplied by the client.
Step 4
interfaceinterface-id
Enter interface configuration mode, and specify the interface connected to the client that is to be
enabled for 802.1X authentication.
Step 5
dot1x port-control autoEnable 802.1X authentication on the interface.
Step 6
end
Return to privileged EXEC mode.
