Difference between the function of the NM_ETH port and that of the ETH port on the TN11AUX board
1. The TN11AUX board uses the NM_ETH port to connect to the NMS server so that the NE where the board resides functions as a gateway NE, or uses this port to connect to another device to implement extended ECC communication. 2. The ETH port of the TN11AUX board can be used only to cascade subracks on the same NE.

Difference between the IN/OUT ports and TX/RX ports on an OTU board
The IN/OUT port of an OTU board is the WDM-side port for connecting to a MUX/DEMUX board, while the TX/RX port is the client-side port for connecting to access equipment.

Differences between the two-port FCoE interface module and four-port FCoE interface module
Two-port FCoE VN2VN interface modules can be directly connected. They can be connected to the lossless Ethernet switches but cannot be connected to FCoE switches. Four-port FCoE VN2VF interface modules cannot be directly connected and must be connected to the FCoE switch for use. They cannot be connected to lossless Ethernet switches. Take note of these differences when configuring the FCoE interface module.
