Usage
Information
This command is found on the 10/100/1000/10000 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.
