Enable Energy Saver on Ports

About this task

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

Note

Note

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

Before you begin

  • 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.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

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

    Note

    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.

  2. 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)

    • a series of slots and ports (slot/port,slot/port,slot/port)

    • all ports on the same slot (slot/all)

    • all ports on the switch (all)

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

Example

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

What to do next

Configure an Energy Saver schedule.
