Configuring NAC Layer 2 802.1x Validation

You can configure NAC Layer 2 802.1x validation, which is also referred to as 802.1x authentication
with a RADIUS server.
Beginning in privileged EXEC mode, follow these steps to configure NAC Layer 2 802.1x validation.
The procedure is optional.
Command
Step 1
configure terminal
Step 2 interface interface-id
Step 3 dot1x guest-vlan vlan-id
Step 4 authentication periodic
or
dot1x reauthentication
Step 5 dot1x timeout reauth-period {seconds |
server}
OL-12247-04
Purpose
Enable MAC authentication bypass.
(Optional) Use the eap keyword to configure the switch to use EAP for
authorization.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Enter global configuration mode.
Specify the port to be configured, and enter interface configuration mode.
Specify an active VLAN as an 802.1x guest VLAN. The range is 1 to
4094.
You can configure any active VLAN except an internal VLAN (routed
port), an RSPAN VLAN, or a voice VLAN as an 802.1x guest VLAN.
Enable periodic re-authentication of the client, which is disabled by
default.
Set the number of seconds between re-authentication attempts.
The keywords have these meanings:
seconds—Sets the number of seconds from 1 to 65535; the default is
•
3600 seconds.
• server—Sets the number of seconds based on the value of the
Session-Timeout RADIUS attribute (Attribute[27]) and the
Termination-Action RADIUS attribute (Attribute [29]).
This command affects the behavior of the switch only if periodic
re-authentication is enabled.
