Setting the Port Roles
To set the authenticator or supplicant roles on the ports in the stack:
1. From the Home page, click the Configuration button.
2. From the Configuration menu, click the Network Security button to
display the 802.1x Port Access tab shown in Figure 85.
Figure 85. 802.1x Port Access Tab
The roles of the ports are displayed in the image of the switch. An “A”
indicates an authenticator port and an “S” a supplicant port. A black
port has not been assigned a port role and is not participating in port-
based access control. This is the default setting for a port.
3. In the switch image, use the Stack ID pull-down menu to choose the
switch that has the authenticator ports you want to configure. If the
switch is already displayed, skip this step.
