Table 123: Green Ethernet Local Interface Status Fields
Field
Description
Interface
The interface associated with the rest of the data in the row. The table displays
all interfaces that are enabled for EEE.
Tw_sys_tx
The system wake time (Tw_sys) that the interface transmits. The wake time is
the amount of time allowed to wake up from the low-power state that occurs
when no data is transmitted.
Tw_sys_tx Echo
The system wake time the interface sends to the link partner when it receives a
Tw_sys_tx request from the link partner.
Tw_sys_rx
The system wake time that the local interface requests from the remote link
partner.
Tw_sys_rx Echo
The remote system's receive Tw_sys that was used by the local system to
compute the Tw_sys that it can support.
Fallback Tw_sys
The value of fallback Tw_sys that the local system requests from the remote
system. The fallback is the second preference of the receiving system when
requesting the Tw_sys from its transmitting partner.
Tx DLL Enabled
The initialization status of the EEE transmit DLL (Data Link Layer) management
function on the local system.
Tx DLL Ready
The DLL ready transmission status of the interface. This field indicates whether
the transmission system initialization is complete and is ready to update/
transmit LLDP Data Units (LLDPDUs) containing the EEE TLVs.
Rx DLL Enabled
The status of the EEE capability negotiation on the local interface.
Rx DLL Ready
The DLL ready receive status of the interface. This field indicates whether the
local interface initialization is complete and is ready to update/receive LLDPDUs
containing EEE TLVs.
Green Ethernet Remote Device Status
For platforms that include Green Energy features, the Green Ethernet Remote Device Status page
shows the information that each EEE (Energy Efficient Ethernet)-enabled interface transmits in the
s to its link partner (the remote system). The TLVs are defined in the IEEE 802.1AB standard
and provide information about the capabilities of the local device.

Table 124: Green Ethernet Remote Device Status Fields
Field
Description
Interface
The interface associated with the rest of the data in the row. The table displays
all interfaces that are enabled for EEE and have received EEE TLVs from a link
partner.
Tw_sys_tx
The system wake time (Tw_sys) that the interface received from its link partner.
Tw_sys_tx Echo
The system wake time the remote system sends to the local interface when it
receives a Tw_sys_tx request from the local interface.
