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 ClientThe 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.AT-9400 Switch
