OSA-Express3 Port Control workspace

The OSA-Express3 Port Control workspace displays control data for the OSA-Express3 Ethernet adapters. The OSA-Express3 Port Control workspace is accessed only as a drill down from the OSA-Express3 Ports Summary workspace using Channel Number and Port Number as link attributes.

Transmitter ON (XON), transmitter OFF (XOFF), and Pause MAC packets are flow control packets between the OSA and the switch to which it is connected. They are used to provide flow control between the two ports. These attributes are of particular interest when the port is at 100% utilization.
