Chapter 31: 802.1x Port-based Network Access Control
364 Section VIII: Port Security
Figure 40. Authenticator Port in Single Operating Mode with a Single
Client
The example in Figure 41 on page 365 illustrates a configuration that uses
the piggy-back mode. Multiple clients are connected to an authenticator
port on the switch through an Ethernet hub or a non-802.1x-compliant
Ethernet switch, such as an unmanaged switch. The operating mode of
the authenticator port on the AT-9400 Switch is set to Single and the
piggy-back mode is enabled. This allows all clients to forward packets
through the port after one client logs on.
