mode. To return the system to autonegotiate speed, use the no form of the speed command.

Usage Guidelines
Keep in mind that both ends of a link must have the same interface speed. A manually configured interface
speed overrides any autonegotiated speed, which can prevent a link from coming up if the configured
interface speed at one end of a link is different from the interface speed on the other end.
Note
Table 46: Relationship Between duplex and speed Commands, on page 672 describes the performance of the
system for different combinations of the duplex and speed modes. The specified duplex command configured
with the specified speed command produces the resulting system action.
