Configuring Ports on a Switch
Configuring Switch Port Speed and Duplex Setting
By default, the switch is configured to use autonegotiation to determine the port speed and duplex
setting for each port. You can manually configure the duplex setting and the speed of 10/100 Mbps
ports.
10BASE-T and 100BASE-TX ports can connect to either 10BASE-T or 100BASE-T networks. By default,
the ports autonegotiate port speed. You can also configure each port for a particular speed (either 10
Mbps or 100 Mbps).
All ports on a stand-alone switch can be configured for half-duplex or full-duplex operation. By default,
the 10/100 Mbps ports autonegotiate the duplex setting.
To configure port speed and duplex setting, use the following command:
config ports <portlist> auto off speed [10 | 100 | 1000] duplex [half | full]
To configure the system to autonegotiate, use the following command:
config ports <portlist> auto on
Switch Port Commands
Table 15 describes the switch port commands.
Table 15: Switch Port Commands
Command Description
config ports <portlist> auto off speed [10 |
100 | 1000] duplex [half | full]
Changes the configuration of a group of ports.
Specify the following:
• auto off — The port will not autonegotiate
the settings.
• speed — The speed of the port.
• duplex — The duplex setting (half- or
full-duplex).
config ports <portlist> auto on Enables autonegotiation for the particular port
type; 802.3u for 10/100 Mbps ports or 802.3z for
Gigabit Ethernet ports.
config ports <portlist> display-string <string> Configures a user-defined string for a port. The
string is displayed in certain show commands (for
example, show ports info). The string can
be up to 16 characters.
config sharing address-based [mac_source |
mac_destination | mac_source_destination |
ip_source | ip_destination |
ip_source_destination]
Configures the part of the packet examined by
the switch when selecting the egress port for
transmitting load-sharing data. This feature is
available using the address-based load-sharing
algorithm, only.
disable ports <portlist> Disables a port. Even when disabled, the link is
available for diagnostic purposes.
disable sharing <port> Disables a load-sharing group of ports.
enable ports <portlist> Enables a port.
