power inline
power inline
To configure the power management mode on Power over Ethernet (PoE) ports, use the power inline
interface configuration command. To return to the default settings, use the no form of this command.
power inline {auto [max max-wattage] | never | police [action {errdisable | log}] | port priority
{high | low}] | static [max max-wattage]}
no power inline {auto | never | police | port priority| static}
Syntax Description
Defaults The default is auto (enabled).
The maximum wattage is 30,000 mW.
The default port priority is low.
Command Default Interface configuration
Command History
Usage Guidelines This command is supported only on PoE-capable ports. If you enter this command on a port that does
not support PoE, this error message appears:
Switch(config)# interface gigabitethernet1/0/1
Switch(config-if)# power inline auto
^
% Invalid input detected at '^' marker.
In a switch stack, this command is supported on all ports in the stack that support PoE.
auto Enables powered-device detection. If enough power is available,
automatically allocates power to the PoE port after device detection.
Allocation is first-come, first-serve.
max max-wattage (Optional) Limits the power allowed on the port. The range is 4000 to
30000 mW. If no value is specified, the maximum is allowed.
never Disables device detection, and disable power to the port.
police Enables policing of the real-time power consumption. For more
information about these keywords, see the power inline police command.
port priority {high | low} Configures the power priority of a StackPower port. In case of a power
supply failure, ports configured as low priority are turned off first. The
default priority is low.
static Enables powered-device detection. Pre-allocates (reserves) power for a
port before the switch discovers the powered device. This guarantees that
the device connected to the interface receives enough power.
Release Modification
12.2(53)SE2 This command was introduced.
