Port Management
Configuring Green Ethernet
Green Ethernet Properties for Ports
The Port Settings page displays the current Green Ethernet and EEE modes per port, and enables
configuring Green Ethernet on a port using the Edit Port Setting page. For the Green Ethernet modes to
operate on a port, the corresponding modes must be activated globally in the Properties page.
EEE settings are only displayed for devices that have GE ports. EEE works only when ports are set to Auto
negotiation. The exception is that EEE is still functional even when Auto Negotiation is disabled, but the port
is at 1GB or higher.
To define per port Green Ethernet settings:
STEP 1
The Port Settings page displays the following:
• Global Parameter Status—Describes the enabled features.
For each port the following fields are described:
• Port—The port number.
• Energy Detect— State of the port regarding Energy Detect mode:
- Administrative—Displays whether Energy Detect mode was enabled.
- Operational—Displays whether Energy Detect mode is currently operating.
- Reason—If Energy Detect mode is not operational, displays the reason.
• Short Reach—State of the port regarding Short Reach mode:
- Administrative—Displays whether Short Reach mode was enabled.
- Operational—Displays whether Short Reach mode is currently operating.
- Reason—If Short-Reach mode is not operational, displays the reason.

NOTE
• 802.3 Energy Efficient Ethernet (EEE)—State of the port regarding the EEE feature:
- Administrative—Displays whether EEE was enabled.
- Operational—Displays whether EEE is currently operating on the local port. This is a function of
whether it has been enabled (Administrative Status), whether it has been enabled on the local port
and whether it is operational on the local port.
