on the LC-EH-GE-50P or the LC-EJ-GE-50P card.
10000 Enter the keyword 10000 to set the interface’s speed to 10000 Mb/s. Auto-negotiation
is enabled. For more information, refer to negotiation auto.

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 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. You can use the speed command to enable the required speed.
