Turning Off EEE on GS108Ev3
Hello,
I need to disable EEE feature from the switch but I do not see any option that does this. It seems like manual specifying the product comes with this feature but this document excludes GS108Ev3 as shown below:
"Note: Power saving options are available on models GS105Ev2, GS105PE, GS116Ev2,
JGS516PE, JGS524Ev2, and JGS524PE."
Is this mean that the product is already equipped with the feature but cannot be turned off?
Please advise.
Everything I read there is a "no". In German people say "Der Weg des geringsten Widerstandes." ... the easy way, easily, with no special hardships, without any great effort. When you carefully read the text and the the attached file with known incompatible unmanaged switches, it mentions two points:
"Although power management should be negotiated automatically in switches that support EEE, it is a
relatively new technology, and some switches do not perform the negotiation properly. This may cause EEE
to be enabled in Dante networks when it is not appropriate, resulting in poor synchronization performance
and occasional dropouts. ""..... It is the responsibility of the user to verify switch compatibility."
There you go. Run your tests, ....
Netgear has bunches of switches validated and tested, for many audio and video applications. The newer M4250 Switch Series comes with ready to deploy predefined profiles for audio Dante, Q-SYS and AES67 profiles are available, as well as an AVB profile requiring an
AVB license sold separately. For video the M4250 offers profiles for NVX, AMX, Q-SYS, NDI, Dante etc. as well as audio/video/control mixed profiles. Note: There is much more - especially around the IGMP Multicast handling - required for these use cases.

Why oh why one does need this? The complete EEE is part of the IEEE 802.3az standard, specifying a signaling protocol, Low Power Idle (LPI) for achieving the power saving during the idle time of Ethernet links. EEE allows PHYs to exchange LPI indications to signal the transition to low power mode when there is no traffic. LPI indicates when a link can go idle and when the link needs to resume after a predefined delay without impacting data transmission.
If there is no EEE (802.3az capable) device is connected to this port, no LPI negotiation will happen, the link will stay up (and consuming serious power).
If there is an EEE peer connected, the connection will be activated again.
So what crazy device or devices will be connected having an issue with EEE (so as we learnt above also supporting EEE [!!!]) or which vendor does require EEE disabled? Remains the question to that very vendor why they support it but require to disable it?!?

Correct. The feature can't be turned off, neither globally on the switch level nor by port on this product.
The switch is being used for pro level audio equipments. Please refer to below:
