Configuring Ports on a Switch
ExtremeWare XOS 11.0 Concepts Guide 71
Enabling and Disabling Switch Ports
By default, all ports are enabled. To enable or disable one or more ports on a modular switch, use the
following commands:
enable port [<port_list> | all]
disable port [<port_list> | all]
For example, to disable slot 7, ports 3, 5, and 12 through 15 on a modular switch, use the following
command:
disable port 7:3,7:5,7:12-7:15
Configuring Switch Port Speed and Duplex Setting
ExtremeWare XOS 11.0 supports the following port types on the Black Diamond 10808:
• 10 Gbps ports
• 10/100/1000 Mbps copper ports
• 1 Gbps SFP gigabit Ethernet interface converter (GBIC) fiber ports
Autonegotiation determines the port speed and duplex setting for each port. You can manually
configure the duplex setting and the speed of 10/100/1000 Mbps ports.
The 10/100/1000 Mbps ports can connect to either 10BASE-T, 100BASE-T, or 1000BASE-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).
SFP GBIC ports are statically set to 1 Gbps, and their speed cannot be modified.
To configure port speed and duplex setting, use the following command:
configure ports <port_list> auto off speed [10 | 100 | 1000 | 10000] duplex [half |
full]
To configure the system to autonegotiate, use the following command:
configure ports <port_list> auto on
Flow control on Gigabit Ethernet ports is enabled or disabled as part of autonegotiation. If
autonegotiation is set to Off on the ports, flow control is disabled. When autonegotiation is turned On,
flow control is enabled.
The 1 Gbps ports both advertise support and respond to pause frames, but they do not initiate pause
frames. 10 G ports always support flow control, and they both initiate and respond to pause frames.
ExtremeWare XOS does not support turning off autonegotiation on the management port.
Turning Off Autonegotiation on a Gigabit Ethernet Port
In certain interoperability situations, you may need to turn autonegotiation off on a fiber gigabit
Ethernet port. Although a gigabit Ethernet port runs only at full duplex, you must specify the duplex
setting.
The following example turns autonegotiation off for port 1 (a gigabit Ethernet port) on a module located
in slot 1 of a modular switch:
configure ports 1:1 auto off duplex full
