Manually configures port speed and duplex setting configuration on one or more ports on a switch.
| port_list | Specifies one or more ports or slots and ports. |
| medium | Specifies the medium as either copper or fiber. Note: This parameter applies to combo ports only on the Summit family switches. |
| speed | Specifies the port speed as either 10, 100, 1000 (1 Gigabit), or 10000 (10 Gigabit) 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. |
Auto on for 1G ports.
Auto off for 10G ports.
You can manually configure the duplex setting and the speed on 10/100 and 10/100/1000 Mbps and fiber SFP gigabit Ethernet ports.
The 8900-10G24X-c, BDXA-10G48X, Summit X670-48x, and X670V-48x ports default to 10G auto off. The user is recommended to change the configuration to 1G auto on (or auto off) when a 1G SFP optic is plugged into the port. In the event, the user does not change user configuration, the port links up at 1G, but a warning message is logged for the user to take corrective action and change the user configuration. Similarly, when the port has been configured to 1G auto on (or auto off) and a SFP+ optic is inserted, the port links up with the correct speed and auto configuration, but a log message recommends that the user configuration be changed to match the optic inserted.
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 for more detailed information on flow control on Extreme Networks devices.)
When configuring combination ports you can specify the medium as copper or fiber. If the medium is not specified for combination ports then the configuration is applied to the current primary medium. The current primary medium is displayed in the Media Primary column of the show ports configuration command output.
Note
The keyword medium is used to select the configuration medium for combination ports. If the port_list contains any non-combination ports, the command is rejected.
When upgrading a switch running ExtremeXOS 12.3 or earlier software to ExtremeXOS 12.4 or later, saved configurations from combo ports (copper or fiber) are applied only to combo ports fiber medium. When downgrading from ExtremeXOS 12.4 or later to ExtremeXOS 12.3 or earlier, saved configurations from combo ports (copper or fiber) are silently ignored. Therefore, you need to reconfigure combo ports during such an upgrade or downgrade.
The following example turns autonegotiation off for slot 2, port 1 at full duplex on a modular switch:
configure ports 2:1 auto off speed 100 duplex full
The following example turns autonegotiation off for port 2 with copper medium and a port speed of 100 Mbps at full duplex:
configure ports 2 medium copper auto off speed 100 duplex full
This command was first available in ExtremeXOS 10.1.
The medium parameter was added in ExtremeXOS 12.4.
This command is available on all platforms.
