462 Configuring Port Characteristics
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 gigabitEthernet
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 gigabitEthernet
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 PowerConnect
7000 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.
NOTE: Cable diagnostics may give misleading results if green mode is enabled
on the port. Disable green mode prior to running any cable diagnostics.
