command
Usage
Information
This command is found on the /1000/10000 Base-T Ethernet interfaces.
When you enable auto, the system performs an automatic discovery to determine the optics installed
and configure the appropriate speed.
When you configure a speed for the 10/100/1000/10000 interface, confirm the negotiation auto
command setting. Both sides of the link must have auto-negotiation either enabled or disabled. For speed
settings of 1000 or auto, the software sets the link to auto-negotiation and you cannot change that
setting.
NOTE: Starting with Dell EMC Networking OS version 7.8.1.0, when you use a copper SFP2 module
with catalog number GP-SFP2-1T in the S25P model of the S-Series, you can manually set its speed
with the speed command. When you set the speed to 10 or 100 Mbps, you can also use the
duplex command.
If you use an active optical cable (AOC), you can convert the QSFP+ port to a 10 Gigabit SFP+ port or 1
Gigabit SFP port. Use the speed command to enable the required speed.
NOTE: If the interface does not come up when you configure 10/100/1000G speed, configure the
interface speed using the speed command manually on both the ends and disable autonegotiation if
it is enabled.
speed (Management interface)
Set the speed for the Management interface.
Syntax
speed {10 | 100 | 1000 | auto}
To return to the default setting, use the no speed command.
Parameters
10 Enter the keyword 10 to set the interface’s speed to 10 Mb/s.
100 Enter the keyword 100 to set the interface’s speed to 100 Mb/s.
1000 Enter the keyword 1000 to set the interface’s speed to 1000 Mb/s.
auto Enter the keyword auto to set the interface to auto-negotiate its speed.
Defaults auto
