4 Configuration
D-Link Web Smart Switch User Manual
Time Range:
Select the PoE time profile configured from Time-Based PoE > Time Range Settings to enable
the time-based PoE function on designated port(s). Default setting is
N/A
.
Priority:
Configure the power supply priority as “Low”, “Normal”, or “High” on designated port(s). Default is
Normal
.
Delay Power Detect:
Configure the delay power detection. Default is Disabled. This switch conforms to
IEEE 802.3af and 802.3at standards. The IEEE PoE standard requires a switch to shut off power to a port if
the power draw is less than 10mA within a 400ms time interval. To support some non-standard devices that
may take longer, you may enable this feature to extend the time interval to 500ms. If the PD is still not
powering on, please contact the vendor of your device for support.
Power Limit:
This function allows you to manually set the port power current limitation to be given to the PD.
To protect the DGS-1210-28P and the connected devices, the power limit function will disable the PoE
function of the port when the power is overloaded. Select from "
Class 1
", "
Class 2
", "
Class 3
",
“Class 4”
and "
Auto
" for the power limit. "
Auto
" will negotiate and follow the classification from the PD power current
based on the 802.3at standard.
User Define:
Check the box and input the power budget (from 1 to 30W) to manually assign an upper limit of
port power budget on designated port(s).

Note: For the PoE Port Settings table, if the
classification was shown as “Legacy PD”, it will be
classified to non-AF PD or Legacy PD.
SNMP > SNMP > SNMP Global Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed
specifically for managing and monitoring network devices. SNMP enables network management stations to
read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential problems in the
Switch or LAN.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the
device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the
MIB specifications and the protocol used to access this information over the network.
The default SNMP global state is disabled. Select Enable and click
Apply
to enable the SNMP function.
