Commands for Configuring Slots and Ports on a Switch
configure ports auto off
configure ports [<portlist> | all | mgmt] auto off {speed [10 | 100 |
1000]} duplex [half | full]
Description
Manually configures port speed and duplex setting configuration on one or more ports on a switch.
Syntax Description
Default
Auto on.
Usage Guidelines
On a modular switch,
<portlist>
can be a list of slots and ports. On a stand-alone switch,
<portlist>
can be one or more port numbers. For a detailed explanation of port specification, see “Modular Switch
Numerical Ranges” or “Stand-alone Switch Numerical Ranges” in Chapter 1.
You can manually configure the duplex setting and the speed of 10/100 Mbps ports, and you can
manually configure the duplex setting on Gigabit Ethernet ports.
Fast Ethernet 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).
Gigabit Ethernet ports are statically set to 1 Gbps, and their speed cannot be modified.
All ports on a stand-alone switch can be configured for half-duplex or full-duplex operation. By default,
the ports autonegotiate the duplex setting.
In certain interoperability situations, it is necessary to turn autonegotiation off on a Gigabit Ethernet
port. Even though a Gigabit Ethernet port runs only at full duplex and gigabit speeds, the command
that turns off autonegotiation must still include the duplex setting.
Gigabit Ethernet ports support flow control only when autonegotiation is turned on. When
autonegotiation is turned off, flow control is not supported.
portlist Specifies one or more ports or slots and ports. On a modular switch, can be a
list of slots and ports. On a stand-alone switch, can be one or more port
numbers. May be in the form 1, 2, 3-5, 2:*, 2:5, 2:6-2:8.
all Specifies all configured ports on the switch. (6.1 and later) See “Usage
Guidelines” for more information.
mgmt Specifies the management port. Supported only for switches that provide a
management port.
speed [10] Specifies 10 Mbps ports.
speed [100] Specifies 100 Mbps ports.
speed [1000] Specifies 1000 Mbps ports. (6.1 and later)
duplex [half] Specifies half duplex; transmitting and receiving data one direction at a time.
duplex [full] Specifies full duplex; transmitting and receiving data at the same time.
