Figure 253. Single Operating Mode with Multiple Clients Using the Piggy-
back Feature - Example 3
The second type of operating mode for an authenticator port is the Multiple
mode. You use this mode when a port is supporting more than one client
and you want each client to log on individually before being permitted to
use the port, perhaps to increase network security. An authenticator port
in this mode can support up to a maximum of 20 clients, with a total
maximum of 480 per switch. You must provide each client with a separate
username and password combination and the clients must provide their
combinations to forward traffic through the switch port.
Selecting the Multiple mode for an authenticator port disables the piggy-
back mode, because this operating mode precludes piggy-backing.
An example of this authenticator operating mode is illustrated in Figure
254. The clients are connected to a hub or non-802.1x-compliant switch
which is connected to an authenticator port on an AT-9400 Series switch.
Each client is given a separate username and password combination to
