670 Section VI: Port Security
D - Piggyback Mode
This parameter controls who can use the switch port in cases where
there are multiple clients using the port (e.g., the switch port is
connected to an Ethernet hub). If set to enabled, the port allows all
clients on the port to piggy-back onto the initial client’s authentication,
forwarding all packets after one client is authenticated. If set to
Disabled, the switch port forwards only those packets from the client
who is authenticated and discards packets from all other users.
Note
This parameter is only available when the authenticator’s mode is
set to Single. For further information, refer to “Authenticator Ports
with Single and Multiple Supplicants” on page 649.
E - Guest VLAN
This parameter specifies the name or VID of a Guest VLAN. The
authenticator port is a member of a Guest VLAN when no supplicant is
logged on. Clients do not log on to access a Guest VLAN. To remove a
Guest VLAN without assigning a new one, enter “none”.
For further information, refer to “Guest VLAN” on page 657.
7. Repeat this procedure starting with Step 4 to configure additional
authenticator ports on the switch.
