SW1 and SW2: Mode of Operation
The GPoE+/Si supports Switch, Directed Switch and Dual Device mode.
The modes are described with MAC learning enabled. When MAC learning is
disabled, unicast packets are forwarded to all ports.

Modes of Operation
Switch Mode
When configured for Switch Mode (factory default), the module operates as a
standard layer 2 switch. Data flow will follow MAC address mapping.

Directed Switch Mode
When an 4-Port model is configured for Directed Switch Mode, traffic from Ports
P1 - P4 is only forwarded to the fiber uplink port F1, preventing the broadcast traffic
from flooding other network ports. Incoming traffic from F1 follows MAC address
mapping.
When an 8-Port model is configured for Directed Switch Mode, traffic from Ports
P1 - P8 is only forwarded to the fiber uplink port F1, preventing the broadcast traffic
from flooding other network ports. Incoming traffic from F1 follows MAC address
mapping.
Directed Switch Mode Single Fiber Port
Models with two fiber ports follow the same RJ-45 data flow as above, with the
addition of fiber port F2 also being forwarded to the fiber uplink port F1.
Directed Switch Mode Dual Fiber Port
