B. Specify User-Based Authentication or Return to Port-
Based Authentication
User-Based 802.1X Authentication.
Syntax: aaa port-access authenticator client-limit < port-list > < 1 - 32 >
Used after executing aaa port-access authenticator < port-list >
(above) to convert authentication from port-based to user-
based. Specifies user-based 802.1X authentication and the
maximum number of 802.1X-authenticated client sessions
allowed on each of the ports in < port-list >. If a port currently
has no authenticated client sessions, the next authenticated
client session the port accepts determines the untagged
VLAN membership to which the port is assigned during the
session. If another client session begins later on the same
port while an earlier session is active, the later session will
be on the same untagged VLAN membership as the earlier
session.
Note: Because a switch allows 802.1X authentication and
Web or MAC authentication to co-exist on the same port, the
sum of authenticated client sessions allowed on a given port
for both 802.1X and either Web- or MAC-authentication
cannot exceed 32.
Port-Based 802.1X Authentication.
no aaa port-access authenticator client-limit
Used to convert a port from user-based authentication to
port-based authentication, which is the default setting for
ports on which authentication is enabled. (Executing aaa
port-access authenticator < port-list > enables 802.1X authenti-
cation on < port-list > and enables port-based authentica-
tion—page 10-19.) If a port currently has no authenticated
client sessions, the next authenticated client session the port
accepts determines the untagged VLAN membership to
which the port is assigned during the session. If another
authenticated client session begins later on the same port
while an earlier session is active, the later session replaces
the currently active session and will be on the untagged
VLAN membership specified by the RADIUS server for the
later session.
