The options are as follows:
•
Half
. Indicates that the interface supports transmission between the devices in only
one direction at a time.
•
Full
. Indicates that the interface supports transmission between the devices in both
directions simultaneously.
•
Auto
. Indicates that speed is set by the auto-negotiation process.
The default is Auto.
Note:
After you change the duplex mode, the switch might be inaccessible for
a number of seconds while the new settings take effect.

From the
Link Trap
menu, select whether or not to send a trap when the link status
changes.
By default, the switch sends a link trap.

From the
Flow Control
menu, select the configuration for IEEE 802.3 flow control.
•
Disable
. If the port buffers become full, the switch does not send pause frames, and
data loss could occur. This is the default setting.
•
Symmetric
. If the port buffers become full, the switch sends pause frames to stop
traffic.
Flow control helps to prevent data loss when the port cannot keep up with the number
of frames being switched. When you enable flow control, the switch can send a pause
frame to stop traffic on the port if the amount of memory used by the packets on the
port exceeds a preconfigured threshold and responds to pause requests from partner
devices. The paused port does not forward packets for the time that is specified in the
pause frame. When the pause frame time elapses, or the utilization returns to a
specified low threshold, the switch enables the port to again transmit frames. The
switch also honors incoming pause frames by temporarily halting transmission.
•
Asymmetric
. If the port buffers become full, the switch does not send pause frames,
and data loss could occur. However, the switch does honor incoming pause frames by
temporarily halting transmission.
