Corrida-5.09 4xGbE Adapter with Switch Function
Adapter Corrida-5.09 designed as the combined device. Depending on configuration, it realizes one of three functions – multiport SFP GbE adapter, embedded switch in PC form factor or network tap.
Unmanaged switch mode
This mode uses the device as a 5-port switch embedded to PC. The fifth port of the switch is connected to the MAC controller and can be accesses via PCI-express bus.
Ethernet tap mode
In this mode the device still functions as a switch, but port 0 and port 4 (system) perform special functions. They can connect a peripheral device with traffic to analyze to port. Using ports 1-3 the device to be analyzed will carry out outward communication. But the packets sent or received via port 0 will be copied to port 4 and sent to the MAC controller. With the help of a network analyzer these packets can be recorded and analyzed.
4-port MAC controller mode
This mode assigns an internal VLAN to each external port of the adapter. Thus, the switch isolates the traffic between ports. The traffic from every external port is closed to the MAC controller only.
