SWITCH PORT COMMANDS
The switch port commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the
following table.
Command Parameters
config ports config ports [<portlist> | all] {speed [auto | 10_half | 10_full |
100_half | 100_full | {1000_full {[master | slave]}}] | flow_control
[enable | disable] | state [enable | disable] | description [<desc 1-
128> | clear_description]}
show ports {<portlist>} {description | err_disabled}
Each command is listed, in detail, in the following sections.
config ports
Purpose Used to configure the Switch’s Ethernet port settings.
Syntax
config ports [<portlist> | all] {speed [auto | 10_half | 10_full | 100_half | 100_full |
{1000_full {[master | slave]}}] | flow_control [enable | disable] | state [enable |
disable] | [description <desc 1-128> | clear_description]}
Description This command allows for the configuration of the Switch’s Ethernet ports. Only the ports
listed in the <portlist> will be affected.
Parameters
<portlist> − Specifies a port or range of ports to be configured.
all − Configure all ports on the Switch.
speed – Allows the user to set the speed of a port or range of ports, with the addition of
one of the following:



auto − Enables auto-negotiation for the specified range of ports.
[10 | 100 | 1000] − Configures the speed in Mbps for the specified range of
ports. Gigabit ports are statically set to 1000 and cannot be set to slower speeds.
[half | full] − Configures the specified range of ports as either full- or half-duplex.
[master | slave] – The master and slave parameters refer to connections running a
1000BASE-T cable for connection between the Switch port and other device capable of
a gigabit connection. The master setting will allow the port to advertise capabilities
related to duplex, speed and physical layer type. The master setting will also determine
the master and slave relationship between the two connected physical layers. This
relationship is necessary for establishing the timing control between the two physical
layers. The timing control is set on a master physical layer by a local source. The slave
setting uses loop timing, where the timing comes form a data stream received from the
master. If one connection is set for 1000 master, the other side of the connection must
be set for 1000 slave. Any other configuration will result in a link down status for both
ports.
flow_control [enable | disable] – Enable or disable flow control for the specified ports.
state [enable | disable] − Enables or disables the specified range of ports.
description <desc 128> - Enter an alphanumeric string of no more than 128 characters
to describe a selected port interface.
clear_description – Enter this command to clear the port description of the selected
port(s).
Restrictions Only administrator-level users can issue this command.
