Command Function
power inline
Use this command to turn
power on for a specific port or
force a port into test mode.
Use the no form to turn off
power for a port.
Syntax:
power inline [auto | test]
no power inline
• auto - The switch automatically detects if a device is connected to the port
and turns power on or off accordingly.
• test - Forces the port into a test mode. In test mode the port continuously
attempts to detect if a device is connected to the port, but does not supply
power.
Default Setting: auto
Command Mode: Interface Configuration
Command Usage: Using the command without an argument enables port
power in auto mode (the same as the power inline auto command).
In the default auto mode, power is automatically supplied when a device is
detected on the port, providing that the power demanded does not exceed
switch’s power budget.
Example:
Console(config)#interface ethernet 1/1
Console(config-if)#power inline auto
Console(config-if)#exit
Console(config)#interface ethernet 1/2
Console(config-if)#no power inline
Console(config-if)#
power inline maximum
allocation
Use this command to limit the
power allocated to specific
ports.
Use the no form to restore the
default setting.
Syntax:
power inline maximum allocation [milliwatts]
no power inline maximum allocation
• milliwatts - The maximum power budget for the port.
Range: 3000 - 15400 milliwatts.
Default Setting: 15400 milliwatts
Command Mode: Interface Configuration
Command Usage: If a device is connected to a switch port and the switch
detects that it requires more than the maximum power allocated to the port,
no power is supplied to the device (the port power remains off).
Example:
Console(config)#interface ethernet 1/1
Console(config-if)#power inline maximum allocation 8000
Console(config-if)#
power inline priority
Use this command to set the
power priority for specific ports.
Use the no form to restore the
default setting.
Syntax:
power inline priority priority
no power inline priority
• priority - The power priority for the port.
Options: 1 (critical), 2 (high), or 3 (low).
Default Setting: 3 (low)
Command Mode: Interface Configuration
Command Usage: If the power demand from devices connected to the
switch exceeds the power budget setting, the switch uses port power priority
settings to control the supplied power. For example:
• A device connected to a low-priority port that causes the switch to exceed
its budget is not supplied power.
• A device connected to a critical or high-priority port that causes the switch to
exceed its budget is supplied power, but the switch drops power to one or
more lower-priority ports.
• Power is dropped from low-priority ports in sequence starting from port
number 1.
Example:
Console(config)#interface ethernet 1/1
Console(config-if)#power inline priority 2
Console(config-if)#
