speed (for 10/100/1000 interfaces)
c e s
Set the speed for 10/100/1000 Base-T Ethernet interfaces. Both sides of a link must be set to the same
speed (10/100/1000) or to auto or the link may not come upSyntax
speed {10 | 100 | 1000 | auto}
To return to the default setting, use the no speed {10 | 100 | 1000} command.

Usage
This command is found on the 10/100/1000 Base-T Ethernet interfaces.
Information
When auto is enabled, the system performs and automatic discovery to determine the optics installed
and configure the appropriate speed.
When you configure a speed for the 10/100/1000 interface, you should confirm
command setting. Both sides of the link should 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.

Starting with FTOS 7.8.1.0, when a copper SFP2 module with catalog number
GP-SFP2-1T is used in the S25P model of the S-Series, its speed can be manually set with the
speed command. When the speed is set to 10 or 100 Mbps, the duplex command can also be
executed.
