Ethernet Port Specific Configuration Fields
The following explains each Ethernet Port Specific Configuration Screen field.
Interface (Read-Only)
Displays the Interface number.
Physical Port (Read-Only)
Displays the number of the physical port on the interface.
Default Speed (Read-Only)
Displays the current operational speed in Mbps. The 9H532-24 can operate at 10
Mbps or 100 Mbps. The 9H531-24 and 9H539-24 modules operate at
100 Mbps.
Default Duplex (Toggle)
The choices are
Half
, for half duplex, or
Full
, for full duplex. If Auto-Negotiation
is disabled for the port, then the port defaults to operate in the setting displayed.
To choose the Default Duplex, see “Selecting and Changing Settings” on page 49.
Auto-Negotiation State (Toggle)
Determines whether Auto-Negotiation is Enabled or Disabled for the specific
port. During auto-negotiation, the port “tells” the device at the other end of the
segment what its capabilities are. If Auto-Negotiation is disabled, the port reverts
to the speed, duplex and flow control settings specified by Default Speed, Default
Duplex, Half Duplex Flow Control and Full Duplex Flow Control fields
respectively.
Advertised Ability (Selectable)
In normal operation, with all capabilities enabled, the port “advertises” that it has
the ability to operate in any mode. A user may choose to set up the port so that
only a portion of the available capabilities are advertised and the others are
disabled. The left field displays the advertised ability of the port, but only
becomes active on ports that have Auto-Negotiation enabled. The status of a
particular ability is displayed in the right field. The “T” in an ability stands for
twisted pair. Possible abilities are listed below. Not all choices listed below will be
available, as the module will display only the choices available to it.
•
10Base-T – 10 Mbps operation
•
10Base-TFD – 10 Mbps full duplex operation
•
100Base-TX – 100 Mbps operation
Auto-Negotiation is not supported on the 9H531-24 and 9H539-24 modules.
