Chapter 11 Configuring IEEE 802.1x Port-Based Authentication
Understanding IEEE 802.1x Port-Based Authentication
Per-User ACLs and Filter-Ids
ACLs configured on the switch are compatible with other devices running Cisco IOS releases.
You can only set any as
 the source in the ACL. 
Note For any ACL configured for multiple-host mode, the source portion of statement must be any. (For 
example, permit icmp any host 10.10.1.1.)
Authentication Manager CLI Commands
The authentication-manager interface-configuration commands control all the authentication methods, 
such as 802.1x, MAC authentication bypass, and web authentication. The authentication manager 
commands determine the priority and order of authentication methods applied to a connected host. 
The authentication manager command
s control generic authentication features, such as host-mode, 
violation mode, and the authentication timer. Generic authentication commands include the 
authentication host-mode, authentication violation, and authentication timer interface 
configuration commands.
802.1x-specific commands begin with the dot1x k
eyword. For example, the authentication 
port-control auto interface configuration command enables authentication on an interface. However, 
the dot1x system-authentication control global configuration command only globally enables or 
disables 802.1x authentication. 
Note If 802.1x authentication is globally disabled, other authentication methods are still enabled on that port, 
such as web authentication.
The authentication manager commands provide the same functionality as earlier 802.1x commands.

feature.
Specify an active VLAN as an 802.1x guest 
VLAN
.
authentication fallback 
fa
llback-profile
dot1x fallback fallback-profile Configure a port to use web authentication as a 
fallback method for clients that do not support 
802.1x authentication.
authentication host-mode 
[mult
i-auth | multi-domain | 
multi-host | single-host]
dot1x host-mode {single-host | 
multi-host | multi-domain}
