command
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.
NOTE: In S3100 series, the speed command is not available on the combo ports in the hybrid
mode. You need to provision the combo port as copper or fiber medium using the combo-port-
type command. Seecombo-port-type.
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.
