High Speed Flow Control Configuration

The High Speed Flow Control Configuration screen (Figure 3-15) allows you to

set the port parameters for installed gigabit MDAs.

Port Indicates the switch port numbers that correspond to the field values in that row of
the screen (for example, the field values in row 2 apply to switch port 2). The values
that you set in the
Switch
row will affect all switch ports and, when the switch is part
of a stack, the values that you set in the
Stack
row will affect all ports in the entire
stack (except the gigabit MDA ports or fiber optic ports, when installed).
Trunk The read-only data displayed in this column indicates the trunks that correspond to
the switch ports specified in the Trunk Mem bers fields of the Trunk Configuration
screen (see “MultiLink Trunk Configuration” on page 3-37).
Status Allows you to disable any of the switch ports. You can also use this field to control
access to any switch port.
