Enable Energy Saver on Ports

About this task

Perform this procedure to enable Energy Saver on a specific port or range of ports.

Note

Energy Saver does not operate on the 5720 Series when you configure local port Auto-Negotiation advertisements to 2500-full or 5000-full.

If you have previously enabled Energy Saver globally, you must disable it globally before enabling Energy Saver on individual ports.
If you have previously enabled Efficiency Mode, you must disable it before enabling Energy Saver on individual ports.

Enter GigabitEthernet Interface Configuration mode:

enable

configure terminal

interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

Note

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
Enable Energy Saver on the specified port:

Identifies the slot and port in one of the following formats: a single slot and port (slot/port), a range of slots and ports (slot/port-slot/port), or a series of slots and ports (slot/port,slot/port,slot/port).

energy-saver port {slot/port[/sub-port] [-slot/port[/sub-port]] [,...]} enable

Enable energy savings on slot 1 port 2:

Switch:1>enable
Switch:1#configure terminal
Switch:1(config)#interface GigabitEthernet 1/2
Switch:1(config-if)#energy-saver port 1/2 enable

Configure an Energy Saver schedule.

The following table defines parameters for the energy-saver command.


Variable	Value
