Web and MAC Authentication
Configuring MAC Authentication
Prerequisites: As implemented in 802.1X authentica-
tion, the disabling of incoming traffic and transmission
of outgoing traffic on a MAC-authenticated egress port
in an unauthenticated state (using the aaa port-access
controlled-directions in command) is supported only if:
The 802.1s Multiple Spanning Tree Protocol (MSTP)
or 802.1w Rapid Spanning Tree Protocol (RSTP) is
enabled on the switch. MSTP and RSTP improve
resource utilization while maintaining a loop-free
network.
The port is configured as an edge port in the
network using the spanning-tree edge-port
command.
For information on how to configure the prerequisites
for using the aaa port-access controlled-directions in com-
mand, see Chapter 4, “Multiple Instance Spanning-Tree
Operation” in the Advanced Traffic Management Guide.
To display the currently configured Controlled Direc-
tions value for MAC-authenticated ports, enter the show
port-access mac-based config command as shown in
Figure 4-6.
Notes:
The aaa port-access controlled-direction in command allows Wake-
on-LAN traffic to be transmitted on a MAC-authenticated egress
port that has not yet transitioned to the authenticated state; the
controlled-direction both setting prevents Wake-on-LAN traffic to be
transmitted on a MAC-authenticated egress port until authentica-
tion occurs.
The Wake-on-LAN feature is used by network administrators to
remotely power on a sleeping workstation (for example, during early
morning hours to perform routine maintenance operations, such as
patch management and software updates)
