Port Modes

The PXIe-8521 includes four ports that can be configured as independent network interfaces on the module. The ports can function in Direct mode or Tap mode. Regardless of mode, traffic on each port can be monitored. When monitoring is enabled, all traffic that is transmitted or received on that port is captured. Each packet is timestamped by both the local time keeper and the port's network time keeper. The local time keeper runs off PXI Clk10 if present on the chassis. Each port has an independent network time keeper, which uses IEEE 802.1AS to synchronize time with other devices on the network.
