Usage Information
This command is found on the 10/100/1000 Base-T Ethernet interfaces.
When you enable auto, the system performs an automatic discovery to determine the optics installed and
congure the appropriate speed.
When you congure a speed for the 10/100/1000 interface, conrm 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.
