Modes of Operation
Switch Mode
When configured for Switch Mode (factory default), the switch 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.
