System > IEEE802.3az EEE Settings
The IEEE 802.3 EEE standard defines mechanisms and protocols intended to reduce the energy
consumption of network links during periods of low utilization, by transitioning interfaces into a low-power
state without interrupting the network connection. The transmitted and received sides should be
IEEE802.3az EEE compliance. By default, the switch enabled the 802.3az EEE function. Users can disable
this feature by individual port via the IEEE802.3az EEE setting page.
From Port / To Port: A consecutive group of ports may be configured starting with the selected port.
State: Enabled or Disabled the IEEE802.3az EEE for the specified ports. By default, all ports are enabled.
Click Apply to implement changes made.
If the connection speed drops down from 1000M to 100M, or the first link up takes longer time, please follow
below steps and check again:
1. Upgrade drivers of your Ethernet adapter or LAN controller for the host PC.
2. Disable EEE function on the switch port.
System > D-Link Discover Protocol Settings
For the D-Link Discovery Protocol (DDP) supported device, this page is an option for you to disable DDP or
