ExtremeWare XOS 10.1 Command Reference Guide 157
configure ports auto off
configure ports <port_list> 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, <port_list> can be a list of slots and ports. For a detailed explanation of port
specification, see “Modular Switch Numerical Ranges” or “Line-Editing Keys” 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.
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.
Example
The following example turns autonegotiation off for slot 2, port 1 on a modular switch:
configure ports 2:1 auto off duplex full
port_list Specifies one or more ports or slots and ports. On a modular switch, can be a
list of slots and ports. May be in the form 1, 2, 3-5, 2:*, 2:5, 2:6-2:8.
speed [10] Specifies 10 Mbps ports.
speed [100] Specifies 100 Mbps ports.
speed [1000] Specifies 1000 Mbps ports.
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.
