Defaults

Interface speed is set via auto-negotiation by default.

Usage Guidelines

This command can be used to force the speed of an interface if autonegotiation is unavailable or undesirable.

If speed is explicitly configured for an interface, the interface duplex should also be explicitly configured. In other words, auto-negotiation should be enabled or disabled identically for both speed and duplex.

Note that specific interface may not support all of the speeds defined above.

This command is valid only in interface context.

Examples

speed 2500
