EEE Commands

This chapter contains the following sections:

eee enable (global)

To enable the EEE mode globally, use the eee enable Global Configuration command. To disable the mode, use the no format of the command.

Syntax

eee enable

no eee enable

Parameters

This command has no arguments or keywords.

Default Configuration

Enabled

Command Mode

Global Configuration mode

User Guidelines

In order for EEE to work, the device at the other end of the link must also support EEE and have it enabled. In addition, for EEE to work properly, auto-negotaition must be enabled; however, if the port speed is negotiated as 1Giga, EEE always works regardless of whether the auto-negotiation status is enabled or disabled.

If auto-negotiation is not enabled on the port and its speed is less than 1 Giga, the EEE operational status is disabled.

Example

switchxxxxxx(config)# eee enable

eee enable (interface)

To enable the EEE mode on an Ethernet port, use the eee enable Interface Configuration command. To disable the mode, use the no format of the command.

Syntax

eee enable

no eee enable

Parameters

This command has no arguments or keywords.

Default Configuration

EEE is enabled.

Command Mode

Interface (Ethernet) Configuration mode

User Guidelines

If auto-negotiation is not enabled on the port and its speed is 1 Giga, the EEE operational status is disabled.

Example

switchxxxxxx(config)# interface gi1/0/1
switchxxxxxx(config-if)# eee enable

eee lldp enable

To enable EEE support by LLDP on an Ethernet port, use the eee lldp enable Interface Configuration command. To disable the support, use the no format of the command.

Syntax

eee lldp enable

no eee lldp enable

Parameters

This command has no arguments or keywords.

Default Configuration

Enabled

Command Mode

Interface (Ethernet) Configuration mode

User Guidelines

Enabling EEE LLDP advertisement enables devices to choose and change system wake-up times in order to get the optimal energy saving mode.

Example

switchxxxxxx(config)# interface gi1/0/1
switchxxxxxx(config-if)# eee lldp enable

show eee

Use the show eee EXEC command to display EEE information.

Syntax

show eee [interface-id]

Parameters

interface-id—(Optional) Specify an Ethernet port.

Defaults

None

Command Mode

Privileged EXEC mode

User Guidelines

If the port is a 10G port, but the link speed is 1G, the EEE Remote status cannot be resolved (and displayed).
