Resetting PoE Parameters
You can override or reset PoE port parameters including power priority, power class, and maximum power level. To do so, you must specify each PoE parameter in the CLI command line.
Changing a PoE Port Power Priority from Low to High
To change a PoE port power priority from low (the default value) to high and keep the current maximum configured power level of 3000, enter commands such as the following example.
device# configure terminal device(config)# interface ethernet 1/1/1 device(config-if-e1000-1/1/1)# inline power priority 2 power-limit 3000
You must specify both the inline power priority and the maximum power level (power-limit parameter), even though you are keeping the current configured maximum power level
at 3000. If you do not specify the maximum power level, the device will apply the
default value. Also, you must specify the inline power priority before specifying
the power limit.
Changing a Port Power Class from 2 to 3
To change a port power class from 2 (7 watts maximum) to 3 (15.4 watts maximum) and keep the current configured power priority of 2, enter commands such as the following example.
device# configure terminal device(config)# interface ethernet 1/1/1 device(config-if-e1000-1/1/1)# inline power priority 2 power-by-class 3
You must specify both the power class and the inline power priority, even though you are not changing the power priority. If you do not specify the power priority, the device will apply the default value of 3 (low priority). Also, you must specify the inline power priority before specifying the power class.
The following example sets PoE parameters on interface 2/1/1 in stack unit 12.
device# configure terminal device(config)# stack unit 12 device(config)# interface ethernet 2/1/1 device(config-if-e1000-2/1/1)# inline power priority 3 power-limit 14000
