To enter Interface Configuration mode for 10G Ethernet interfaces 3, 4, 5, 12, and 14 on a standalone switch, use the following command: console(config)#interface range tengigabitEthernet 1/0/35,1/0/12,1/0/14 NOTE: To switch to another interface or range of interfaces, enter the interface command while in Interface Configuration mode. It is not necessary to exit Interface Configuration mode to select a different interface. 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 N-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. EEE requires auto-negotiation to be enabled on the port. NOTE: Cable diagnostics may give misleading results if green mode is enabled on the port. Disable green mode prior to running any cable diagnostics. Switchport Modes Each port on the Dell Networking N-Series switches can be configured to be in one of the following modes: • Access-Access ports are intended to connect end-stations to the system, especially when the end-stations are incapable of generating VLAN tags. Access ports support a single VLAN (the PVID). Packets received untagged are processed as if they are tagged with the access port PVID. Packets 632 Port Characteristics
