9.4. Jumbo Frame Support

The ability to support jumbo frames varies by port due to the differences in MAC layers and PHYs used in the port’s design. Below is a summary of each port’s capabilities.

Note 1: PLCA symbol decoding must be enabled in the hardware configuation.

9.5. Ethernet Hardware Time Stamping

All ICS hardware generate timestamps for Ethernet messages that are sent and received. Due to some necessary design differences between products, there are some slight differences in exactly when the timestamps are recorded relative to the actual transmission or receipt of the frame.
