Configuring Energy Efficient Ethernet (802.3az)
Energy Efficient Ethernet (EEE) is a protocol to allow ports to operate in idle or low power mode when
there is no traffic to send. When EEE is enabled on a port it will advertise its EEE capability to its link
partner. If the partner supports EEE they will operate in EEE mode. If the partner does not support EEE
the ports will operate in legacy mode. This allows EEE capable switches to be deployed in existing
networks avoiding backward compatibility issues.
• EEE is only applicable to 10GBase-T ports.
• The LLDP option in IEEE 802.3az standard is not currently supported.
To enable the EEE capability on the switch use the interfaces eee command. For example, enter:
-> interfaces 1/1 eee enable
Configuring Split-Mode
Some OmniSwitch models support 4X10G splitter cables to allow a 40G port to be configured as four 10G
ports. The interfaces split-mode command is used to configure the mode (auto, 40G, 4X10G).
When a splitter cable is used the port numbering scheme changes to accommodate the four 10G ports by
using letters a, b, c, d to refer to the 10G sub-ports. When referring to a single sub-port the port letter
should be used to differentiate between all the sub-ports. If no letter is given the command assumes port
'a', for example.
-> show interfaces 1/1/1 - refers to interface 1/1/1a
-> show interfaces 1/1/1a - refers to interface 1/1/1a
-> show interfaces 1/1/1d - refers to interface 1/1/1d
When referring to a range of ports the lettered sub-ports are implied, for example:
-> show interfaces 1/1/1-2 - refers to interfaces 1/1/1a, 1b, 1c, 1d and 1/1/2a,
2b, 2c, 2d
-> show interfaces 1/1/1a-1c - refers to interfaces 1/1/1a, 1b, 1c
-> show interfaces 1/1/1-2a - refers to interfaces 1/1/1a, 1b, 1c, 1d, and 1/1/
2a.
Configuring Beacon LED
The Beacon LED feature provides a mechanism to allow an administrator to configure the color and the
mode of a port LED using the interfaces beacon command. This can useful in the following scenarios:
• Port identification: Can help to identify a particular port(s) needing attention or where a cable may
need to be swapped. Manually changing the color or mode of the port LED can help to guide a
technician to a particular port. This can also be helpful in a highly dense mesh of cabling.
• Power Savings: Large Data Centers are looking for ways to reduce power consumption. One way could
be to power off every LED on every node if operating properly and only use the LEDs for indicating
ports that need attention.
• Tracking link activity: Servers are often configured in clusters for certain functions or applications.
Ports could be color coded to differentiate between clusters.
