Hi, On that switch ports 5-20 support green ethernet. Page 70 [URL]
I just got a Dell N1124T-ON switch for my expanding home network. I chose this particular model because of its low power consumption (fanless) and the 4 SFP+ ports. The switch came with firmware v6.4.1.4 which I immediately updated to v6.6.0.10. Upon checking the features through the web interface I noticed Energy Efficient Ethernet (802.3az/EEE) is off for ports 21-28. I tried to enable it but the switch did not allow it. On the CLI I get following output when I list the green features:     Port 21 to 28 show "Not supported"? Yet the user manual (June 2017 Rev A04) clearly states the following (page 642): All integrated 1G and module-based 10G copper ports on Dell EMC Networking N-Series switches are capable of utilizing the Energy Detect and EEE modes for reduced power consumption. Is this a bug in the firmware or an undocumented hardware limitation?
N1124T-ON - EEE (802.3az) not supported on ports 21-28?
