Sets an interface's power priority to either
insufficient for all PoE interfaces, the low priority interfaces are shut
down before the high priority interfaces. Among interfaces that have the
same assigned priority, the power priority is determined by port number,
with lower- numbered ports having higher priority.
When included in the configuration, enables the logging of power
consumption records on an interface. Logging occurs every five minutes
for one hour unless you specify a different

maximum power allowed is the same as the default—either 15.4 W for
switches that support IEEE 802.3af (PoE) or 30.0 W for switches that

When included in the configuration, disables PoE on the interface. The
interface maintains network connectivity but no longer supplies power
to a connected powered device. Power is not allocated to the interface.
To configure PoE:
To change power management mode from the default class mode to static mode:
1.
[edit poe]
user@switch# set management static
NOTE: On an EX2200 switch, we recommend that you do not change the
default management mode. The PoE power budget for an EX2200 switch
is 405 W. If you change the power management mode to static mode, the
PoE controller allocates 30.0 W for each port on the EX2200 switch, which
means only 13 ports receive power. With the default priority settings, the
13 ports that receive power are the first 13 ports.
In class mode, on the other hand, the PoE controller does not allocate
power to a port until a powered device is connected. The class of the
connected device determines the amount of power allocated. Thus in
class mode, any PoE port can be used to power a device and all the PoE
ports on the switch can be used as long as the combined power demand
does not exceed 405 W.
To reserve a specified wattage of power in case of a spike in PoE consumption:
