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 6,
Displaying Ethernet Statistics
.

This option is not available from a Telnet or local session.

Enable this port
Disable (partition) this port
These selections allow you to manually disable a port in the switch so
that 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. Enable is the default for all ports.

Auto-negotiate
Full-duplex
Half-duplex
These three selections control the duplex mode of the port. 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.
