| never | static [max max-wattage]}
Example:
Switch(config-if)# power inline
auto
Step 4

Purpose
Enters global configuration mode.
Specifies the physical port to be configured, and enters interface configuration
mode.
Configures the PoE mode on the port. The keywords have these meanings:
• auto—Enables powered-device detection. If enough power is available,
automatically allocates power to the PoE port after device detection. This
is the default setting.
• max max-wattage—Limits the power allowed on the port. The range for
PoE+ ports is 4000 to 30000 mW. If no value is specified, the maximum
is allowed.
• never —Disables device detection, and disable power to the port.
Note
• static—Enables powered-device detection. Pre-allocate (reserve) power
for a port before the switch discovers the powered device. The switch
reserves power for this port even when no device is connected and
guarantees that power will be provided upon device detection.
The switch allocates power to a port configured in static mode before it allocates
power to a port configured in auto mode.
Returns to privileged EXEC mode.
Displays PoE status for a switch or a switch stack, for the specified interface,
or for a specified stack member.
The module switch-number keywords are supported only on stacking-capable
switches.

Configuring a Power Management Mode on a PoE Port
If a port has a Cisco powered device connected to it, do not use the
power inline never command to configure the port. A false link-up
can occur, placing the port into the error-disabled state.
