Configuring Ports on a Switch
To configure the system to autonegotiate, use the following command:
config ports <portlist> auto on
Flow control is supported only on Gigabit Ethernet ports. It is enabled or disabled as part of
autonegotiation. If autonegotiation is set to off, flow control is disabled. When autonegotiation is turned
on, flow control is enabled.
Turning Off Autonegotiation for a Gigabit Ethernet Port
In certain interoperability situations, you may need to turn autonegotiation off on a Gigabit Ethernet
port. Even though a Gigabit Ethernet port runs only at full duplex, you must specify the duplex setting.
The following example turns autonegotiation off for port 4 (a Gigabit Ethernet port) on a stand-alone
switch:
config ports 4 auto off duplex full
Switch Port Commands
Table 20 describes the switch port commands.
Table 20: 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 port all 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.
enable sharing <port> grouping <portlist>
{address-based}
Defines a load-sharing group of ports. The ports
specified in <portlist> are grouped to the
master port. The optional load-sharing algorithm,
address-based, uses addressing information as
criteria for egress port selection.
