ports each. Each group multiplexes traffic into a single full-duplex gigabit link to the switch fabric.
To take advantage of this architecture, use a single port in each group before using all of the ports in
any particular group. Table 38 lists the port groups for the GM-16T

NOTE
If congestion is detected on a port with flow control enabled, a flow control PAUSE frame is sent out
that port. The PAUSE frame is not sent out on the other ports in the group.
