Port Setting
The PORT SETTING menu is used to configure individual ports. This
section will explore several aspects concerning the port setting menu.
Auto-Negotiation
All Switch ports support auto-negotiation. Auto-negotiation is the default
setting for all ports.
In auto-negotiation mode, the switch learns the settings of the link partner
and configures itself to the highest possible transfer rate settings provided
that the link partner also supports auto-negotiation.
In some conditions you should set the connection mode manually, such as
when the link partner does not support auto-negotiation. Please see the
section titled "Configuring Port Settings" on page 3-25 for port setting
information.
Note that if the link partner does not support auto-negotiation, the Switch
may be left in AUTO-NEGO mode. In this situation, the Switch will still be
able to detect the correct speed, but will default to half-duplex mode. It is
therefore recommended that in this situation, the connection mode be set
manually.
While AUTO-NEGO is set, the speed and duplex selections are no longer
available. The speed and duplex will be decided by the result of the
negotiation with the link partner. By contrast, if either the speed or duplex is
selected, the AUTO-NEGO function will not work. It forces the port to run in
the set mode.
Setting the port speed forces the port to use the selected speed only, if the
device being contacted is set at a different speed, the data will not be sent.
When a setting is selected, an asterisk symbol ('*') will be added to the first
character of the string. This makes it convenient to check what the settings
for these ports are. These settings can be viewed through the PORT
