[Solved] Energy-Efficient Ethernet on single interface

[BIGFAT]

Hallo everyone, how can i enable Energy-Efficient Ethernet on a single interface (for example wan)?
Thanks in advance.

need to know the device / chipset...

typically ethtool will let you get/set this... but for alot of things on openwrt this creates more issues than it's worth ( generally a client/switch device thing )... and is often not available... ( you may need to recompile or edit C )

Thank you, and well i just want to give it a shot: Its a pi4 b with 2 rtl8152 nics.

ethtool --show-eee eth1

appears-to-be-default-on-w-recent-master-if-negotiated-with-other-end

[root@dca632 /usbstick 42°]# ethtool --show-eee eth1
EEE Settings for eth1:
	EEE status: enabled - active
	Tx LPI: disabled
	Supported EEE link modes:  100baseT/Full 
	                           1000baseT/Full 
	Advertised EEE link modes:  10baseT/Full 
	                            100baseT/Half 
	Link partner advertised EEE link modes:  100baseT/Full 
	                                         1000baseT/Full

switch off example (on for back on may need to bring the interface up/down);

ethtool --set-eee eth1 eee off

how can i enable Energy-Efficient Ethernet on a single interface

Or as suggested in UCI:

# in /etc/config/network

config switch_port
	option device 'switch0'
	option port '<port_number>'
	option enable_eee '1'

See:

[SOLVED] Can't enable Energy Efficient Ethernet EEE 802.3az on AR8327

I found the solution: https://openwrt.org/docs/guide-user/base-system/basic-networking THE DOCUMENTATION IS WRONG: name string yes (none) defines which switch to configure This attribute is NOT name, it's DEVICE: enable_eee: 1 igmp_snooping: 0 pvid: 1 link: port:1 link:up speed:1000baseT full-duplex txflow rxflow eee100 eee1000 auto config switch_port option device 'switch0' option port '1' option enable_eee '1'

And for issues:

Random packet loss with OpenWrt

EEE, do you mean Energy-Efficient Ethernet? Unless you are referring to your device only, EEE is supported in OpenWrt; but: it probably won't make your latency go down (there is a slight delay when re-powering the port) it has to be supported by the device connected to the port And pause return...do you mean hardware flow control??? Yea, I doubt many supported devices even had that built in, hardware NAT, yes - pause return, no.

# in /etc/config/network

config switch_port
	option device 'switch0'
	option port '<port_number>'
	option enable_eee '1'

This is for the ports on a switch. What i wanted was about a single interface and i already got the right answer. But thank you anyway

@BIGFAT

about a single interface

@lleachii

option device

You're welcome.
