Configuring Port Characteristics
483
For many features, you can configure a range of interfaces. When you enter
Interface Configuration mode for multiple interfaces, the commands you
execute apply to all interfaces specified in the range.
To enter Interface Configuration mode for a range of interfaces, include the
keyword range and specify the interfaces to configure. For example, to apply
the same configuration to ports 1-10 on a standalone switch, use the
following command:
console(config)# interface range tengigabitEthernet
1/0/1-10
To enter Interface Configuration mode for ports 3, 4, 5, 12, and 14 on a
standalone switch, use the following command:
console(config)# interface range tengigabitEthernet
1/0/3-5,1/0/12,1/0/14
What Are the Green Ethernet Features?
The Green Ethernet feature supports two per-port power-saving modes:
• Energy-detect Mode
• EEE
All integrated 1G and module-based 10G copper ports on Dell Networking
series switches are capable of utilizing the Energy Detect and EEE modes for
reduced power consumption.
When the Energy Detect mode is enabled and the port link is down, the PHY
automatically goes down for short period of time and then wakes up to check
link pulses. This mode reduces power consumption on the port when no link
partner is present.
EEE enables ports to enter a low-power mode to reduce power consumption
during periods of low link utilization. EEE is defined by IEEE 802.3az. EEE
enables both the send and receive sides of the link to disable some
functionality for power savings when the link is lightly loaded.
NOTE:
You can switch to another interface or range of interfaces by entering the
interface command while in Interface Configuration mode. It is not necessary to
exit Interface Configuration mode to select a different interface.
