Commands for Configuring Slots and Ports on a Switch
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
314
configure ports auto off
configure ports <port_list> auto off speed [10 | 100 | 1000 | 10000] 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 for 1 G ports.
Auto off for 10 G ports.
Usage Guidelines
You can manually configure the duplex setting and the speed on 10/100/1000 Mbps and fiber SFP
Gigabit Ethernet ports.
SFP gigabit Ethernet ports are statically set to 1 Gbps, and their speed cannot be modified. However,
you
can
set the speed on the 100/1000 FX/LX SFP GBIC ports (available only on the Black Diamond
8800 series switch, the BlackDiamond 12804 switch, and the Summit X450 family of switches) to either
100 Mbps or 1 Gbps.
In certain interoperability situations, it is necessary to turn autonegotiation off on a fiber 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. (See the
ExtremeWare XOS Concepts Guide
for more detailed information on flow control on Extreme Networks devices.)
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.
speed [10]
Specifies 10 Mbps ports.
speed [100]
Specifies 100 Mbps ports.
speed [1000]
Specifies 1000 Mbps (1 Gigabit) ports.
speed [10000]
Specifies 10000 Mbps (10 Gigabit) 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.
