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 LLDP (Link Layer Discovery Protocol) TLVs (type length values) 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.

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.
Tw_sys_rx	The system wake time that the remote link partner requests from the local interface.
Tw_sys_rx Echo	The local system's receive Tw_sys used by the remote system to compute the Tw_sys that it can support.
Fallback Tw_sys	The value of fallback Tw_sys that the remote system requests from the local system. The fallback is the second preference of the receiving system when requesting the Tw_Sys from its transmitting partner.
