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