Optimizing Port Usage
10.1 Overview
This chapter includes:
•
Configuring port, status, mode (speed and duplex), and flow control parameters.
•
Configuration screens corresponding to the port numbers on the front of the switch.
10.2
CLI: Viewing Port Status and Configuring Port Parameters
From the CLI commands, you can configure and view all port parameter settings and view all port
status indicators.
10.2.1 Port Status and Configuration Features
Status or Parameter
Description
---------------------------------- --------------------
Status
Enable
(default): The port is ready for a network connection.
Disable:
The port will not operate even when properly connected
in a network. Use this setting if the port needs to be shut down
for diagnostic purposes or while you are making topology
changes.
Link
Up
: The port senses a linkbeat.
Down
: The port is not enabled, has no cables connected, or is
experiencing a network error. For troubleshooting information,
see the installation manual you received with the switch. See also
chapter 10, “ Troubleshooting” (in this manual).
Mode
The port’s speed and duplex (data transfer operation) setting.
10/100Base-T ports
:
•
Auto
(default): Senses speed and negotiates with the port at the
other end of the link for data transfer operation (half-duplex or
full-duplex).
Note:
Ensure that the device attached to the port is configured for
the same setting that you selected here. Also, if “ Auto” is used,
the device to which the port is connected must operate in
compliance with the IEEE 802.3u “Auto Negotiation” standard
for 100Base-T networks. If the other device does not comply with
the 802.3u standard, or is not set to “Auto”, then the port
configuration on the switch must be manually set to match the
port configuration on the other device.
To see what the switch negotiated for the Auto setting, use the
CLI
show port
command.
