MIB Trap The Switch sends traps (monitoring event notification) to an SNMP (Simple Network Management
Protocol) manager when an event occurs. See Section 26.6.1 on page 195 for more information
on SNMP, MIB (Management Information Base), and SNMP traps.
Select ON to allow sending of MIB Trap when the following situations occur:
• Situation 1 –
Trap sent whenever a PoE port status change occurs (PoE port delivers power or delivers no
power to a PD (powered device)
• Situation 2 –
Trap sent in cases where the total power usage exceeds the PoE usage threshold
• Situation 3 –
Trap sent if total usage power decreases below the PoE usage threshold (only if previous total
power usage exceeded the PoE usage threshold and a trap was sent).
Note: If the MIB Trap is ON, you must also configure:
• SNMP trap destination (SYSTEM > SNMP > SNMP), SNMP trap group (SYSTEM > SNMP > SNMP
Trap Group) and SNMP trap port (SYSTEM > SNMP > SNMP Trap Port) for Situation 1
• SNMP trap destination and SNMP trap group for Situation 2 and Situation 3.
See Section 26.2 on page 189 for more information on configuring SNMP.
PoE Usage
Threshold (%)
Enter a number ranging from 1 to 99 to set the threshold. The Switch will generate a trap and/or
log when the actual PoE usage is higher than the specified threshold.
Port This is the port index number.
* 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.
Changes in this row are copied to all the ports as soon as you make them.
Active 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.
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.
