Understanding IEEE 802.1x Port-Based Authentication
Per-User ACLs and Filter-Ids
In releases earlier than Cisco IOS Release 12.2(50)SE, an ACL configured on the switch is not
compatible with an ACL configured on another device running Cisco IOS software, such as a
Catalyst 6000 switch.
In Cisco IOS Release 12.2(50)SE or later, the ACLs configured on the switch are compatible with other
de
vices running Cisco IOS releases.
You can only set any as th
e 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 commands control generic authentication features, such as host-mode,
v
iolation 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 do
t1x keyword. 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.
3. Supported in Cisco IOS Release 12.2(50)SE and later.
4. For clients that do not support 802.1x authentication.
