Usage Guidelines

The port-auto-sleep enable command enables electrical port dormancy. If this function is enabled on a port, the port enters the energy-saving mode when no carrier wave signals are transmitted on the port. When carrier wave signals are transmitted on the port, the port exits the energy-saving mode. Port sleep does not affect functioning of the port.

This command can be used on electrical interfaces and combo interfaces working as electrical interfaces.

The port sleeping function is enabled by default on the ES5D21X02T01 electrical sub-card supported by the S5720-EI, the ES5D21X08T00 electrical sub-card supported by the S5730-HI, S5731-H, and S5731S-H, and cannot be disabled.
