8.9 Interface Setup
An IPv6 address is configured on a per-interface basis. The interface can be a physical interface (for
example, an Ethernet port) or a virtual interface (for example, a VLAN). The Switch supports the VLAN
interface type for IPv6 at the time of writing.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set
the common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
PD Select this to provide power to a PD connected to the port.
If left unchecked, the PD connected to the port cannot receive power from the Switch.
PD Priority When the total power requested by the PDs exceeds the total PoE power budget on the Switch,
you can set the PD priority to allow the Switch to provide power to ports with higher priority.
Select Critical to give the highest PD priority on the port.
Select High to set the Switch to assign the remaining power to the port after all critical priority
ports are served.
Select Low to set the Switch to assign the remaining power to the port after all critical and high
priority ports are served.
Power-Up Set how the Switch provides power to a connected PD at power-up.
802.3af - the Switch follows the IEEE 802.3af Power over Ethernet standard to supply power to the
connected PDs during power-up.
Legacy - the Switch can provide power to the connected PDs that require high inrush currents at
power-up. Inrush current is the maximum, instantaneous input current drawn by the PD when first
turned on.
Pre-802.3at - the Switch initially offers power on the port according to the IEEE 802.3af standard,
and then switches to support the IEEE 802.3at standard within 75 milliseconds after a PD is
connected to the port. Select this option if the Switch is performing 2-event Layer-1 classification
(PoE+ hardware classification) or the connected PD is NOT performing Layer 2 power
classification using Link Layer Discovery Protocol (LLDP).
802.3at - the Switch supports the IEEE 802.3at High Power over Ethernet standard and can supply
power of up to 30W per Ethernet port. IEEE 802.3at is also known as PoE+ or PoE Plus. An IEEE
802.3at compatible device is referred to as Type 2. Power Class 4 (High Power) can only be used
by Type 2 devices. If the connected PD requires a Class 4 current when it is turned on, it will be
powered up in this mode.
Max Power
(mW)
Specify the maximum amount of power the PD could use from the Switch on this port.
Time Range Select a pre-defined schedule (created using the Advanced Application > Time Range screen)
to control when the Switch enables PoE to provide power on the port.
If you leave this field blank, PoE is disabled on the port.
Apply Click Apply to save your changes to the Switch’s run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Cancel Click Cancel to begin configuring this screen afresh.
