log onto and forward traffic through the AT-9400 Series switch. Of course,
the combinations must be defined on the RADIUS authentication server.
The switch prompts a client for the information the first time they try to
pass a packet through the authenticator port. The port accepts and
forwards traffic only from those clients who successfully log on and denies
access to all other users.

Figure 254. Authenticator Port in Multiple Operating Mode - Example 1

The next example of the multiple mode in Figure 255 shows two AT-9400
Series switches. The clients connected to switch B have to log on to port 6
on Switch A when they pass a packet to that switch for the first time.

There are several things to note about interconnecting two 802.1x-
compliant devices using the Multiple operating mode of an authenticator
port. In order for switch B in our example to pass the RADIUS messages
to switch A, it must be able to log on to port 6 on switch A. That is why port
11 on the lower switch is configured as a supplicant. If its role is set to
none, port 6 on switch A will discard the packets because switch B would
not be logged on to the port.

Also note that the ports where the clients are connected on switch B are
set to the none role. This is because a client can log on only once. If, in this
