If you are running the Omega program from a web browser, you
can display this window by clicking on a port in the graphical
image of the managed switch.
4. Toggle the options as desired.
Any changes to the port settings are activated immediately on the
port. The options are described below.
Receive Statistics Graph
This option displays performance statistics for the port,
specifically the number and types of frames and errors that have
occurred on the port. For further information on port statistics,
refer to Chapter 5, Displaying Ethernet Statistics.
This option is not available from a local or Telnet management
session.
Enable this port
Disable (partition) this port
These selections allow you to manually disable or enable a port in
the stack. When a port is disabled, it no longer receives or sends
packets. You might want to disable a port and prevent packets
from being forwarded if a problem occurs with the node or cable
connected to the port. Once the problem has been fixed, you can
enable the port again to resume normal operation. You can also
disable an unused port to secure it from unauthorized
connections. The default is enabled.
Auto-negotiate
Full-duplex
Half-duplex
These three selections control the duplex mode of the port. You
can also use these selections on an AT-8324 switch to control port
speed.
Full-duplex means that the port can both send and receive data
simultaneously. You can select this setting for a port if you know
that the device connected to the port supports full-duplex.
Half-duplex means the port can send or receive data, but not both
at the same time. Use this setting if you know that the device
connected to the port supports half-duplex mode.
Auto-negotiate means that the port negotiates with the
connected device to automatically configure to the highest
common setting. This setting eliminates the need to reconfigure
the port if you change the type of device connected to the port.
Both end devices need to be auto-negotiation compliant (802.3u)
for the best possible performance settings. If a connected device
is not compliant, it should only be configured for half-duplex.
Auto-negotiate is the default for all ports.
