DESCRIPTION
Select Loop Guard Active to enable loop guard on the port. You have to globally enable
loop guard by selecting the Active Loop Guard field before you enable it on the port.
This field is only available for ZyXEL's Ethernet Switch PWR models. Select the check box to
enable PoE (Power over Ethernet) on this port. Clear the check box to disable it on the port.
This field is only available for ZyXEL's Ethernet Switch PWR models. This field displays the
DSCP (DiffServ Code Point) number (between 0 and 63) for the port.
This field is only available for ZyXEL's Ethernet Switch PWR models.
When the total power requested exceeds the total PoE power budget the PoE device can
provide, you can set the priority level to have the PoE device supplies power according to
different priority levels. The priority from high to low is Critical > High > Low.
Select Critical if the traffic flow through the port is very sensitive to jitter (for example,
voice traffic).
Select High if the traffic flow through the port is important but non-critical. The PoE device
supplies power to the ports only after all critical-priority ports are served.
Select Low if the traffic flow through this port is non-critical and can tolerate some delay.
The PoE device supplies power to the ports only after all high-priority ports are served.
Click Apply to save your changes.
Click Reset to discard your changes and reset the fields to their last saved settings.
