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

EEE is 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 te1/0/1 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 te1/0/1 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).

Examples

Example 1 – The following displays brief Information about all ports.

switchxxxxxx# show eee   EEE globally enabled   EEE Administrate status is enabled on ports: te1/0/1-2, te1/0/4   EEE Operational status is enabled on ports: te1/0/1-2, te1/0/4   EEE LLDP Administrate status is enabled on ports: te1/0/1-3   EEE LLDP Operational status is enabled on ports: te1/0/1-2

Example 2 – The following is the information displayed when a port is in the Not Present state; no information is displayed if the port supports EEE.

switchxxxxxx# show eee te1/0/1 Port Status: notPresent   EEE Administrate status: enabled   EEE LLDP Administrate status: enabled

Example 3 – The following is the information displayed when the port is in status

DOWN.

switchxxxxxx# show eee te1/0/1   Port Status: DOWN   EEE capabilities:   Speed 10M: EEE not supported   Speed 100M: EEE supported   Speed 1G: EEE supported   Speed 10G: EEE not supported   EEE Administrate status: enabled   EEE LLDP Administrate status: enabled

Example 4 – The following is the information displayed when the port is in status UP and does not support EEE.

Example 5 – The following is the information displayed when the neighbor does not support EEE.

switchxxxxxx# show eee te1/0/4   Port Status: UP   EEE capabilities:   Speed 10M: EEE not supported   Speed 100M: EEE supported   Speed 1G: EEE supported   Speed 10G: EEE not supported   Current port speed: 1000Mbps   EEE Remote status: disabled   EEE Administrate status: enabled   EEE Operational status: disabled (neighbor does not support)   EEE LLDP Administrate status: enabled   EEE LLDP Operational status: disabled

Example 6 – The following is the information displayed when EEE is disabled on the port.

switchxxxxxx# show eee te1/0/1   Port Status: UP   EEE capabilities:   Speed 10M: EEE not supported   Speed 100M: EEE supported   Speed 1G: EEE supported   Speed 10G: EEE not supported Current port speed: 1000Mbps   EEE Administrate status: disabled   EEE Operational status: disabled   EEE LLDP Administrate status: enabled   EEE LLDP Operational status: disabled

Example 7 – The following is the information displayed when EEE is running on the port, and EEE LLDP is disabled.

switchxxxxxx# show eee te1/0/2   Port Status: UP   EEE capabilities:   Speed 10M: EEE not supported   Speed 100M: EEE supported   Speed 1G: EEE supported   Speed 10G: EEE not supported Current port speed: 1000Mbps   EEE Remote status: enabled   EEE Administrate status: enabled   EEE Operational status: enabled   EEE LLDP Administrate status: disabled   EEE LLDP Operational status: disabled   Resolved Tx Timer: 10usec   Local Tx Timer: 10 usec   Resolved Timer: 25 usec   Local Rx Timer: 20 usec

Example 8 – The following is the information displayed when EEE and EEE LLDP are running on the port.

switchxxxxxx# show eee te1/0/3   Port Status: UP   EEE capabilities:   Speed 10M: EEE not supported   Speed 100M: EEE supported   Speed 1G: EEE supported   Speed 10G: EEE not supported Current port speed: 1000Mbps   EEE Remote status: enabled   EEE Administrate status: enabled   EEE Operational status: enabled   EEE LLDP Administrate status: enabled   EEE LLDP Operational status: enabled   Resolved Tx Timer: 10usec   Local Tx Timer: 10 usec   Remote Rx Timer: 5 usec   Resolved Timer: 25 usec   Local Rx Timer: 20 usec   Remote Tx Timer: 25 usec
