power inline
Enable inline power and configure maximum power allocation with priority for the powered device connected to an interface.
C9000 Series
Syntax
power inline {[max_milliwatts ]| priority {critical | high | low}}
To disable a device that has been enabled for PoE power supply, use the no power inline command.
Parameters
max_milliwatts (OPTIONAL) Specify the maximum amount of inline power allocation to a powered device
connected to the interface. Range is 440–30000 milliwatts (mWs). The default value is
30000 mWs.
NOTE: The max_milliwatt configuration is effective only in Static mode.
priority Enter the keyword priority to specify the PoE priority for the powered device
connected to the interface. Default priority value is low.
critical Enter the keyword critical to set the PoE priority level as critical.
high Enter the keyword high to set the PoE priority level as high.
low Enter the keywordlow to set the PoE priority as low.
Defaults Default priority is low.

Usage information
The power inline [max_milliwatts} command enables inline power supply to an interface. You can
specify the maximum amount of power allocation to a device in max-milliwatts, within a range of 440–30000 mW.
If a specific power supply value is not configured, the default value of 30,000 mW is configured as the maximum
power for allocation to powered devices. You can disable the inline power supply to a port using the no power
inline command.
The power inline priority command allows you to specify the power inline priority for an interface when
a power shortage occurs. PoE is removed from ports configured with low priority first, then ports configured
with high priority are disabled. The ports configured with critical priority are the last ports disabled during a
power shortage. When two or more ports are configured with same priority level, the ports with higher interface
numbers are disabled first. For example, if ports 1, 2, 47, and 48 are all configured with a
low priority and there is a
shortage of inline power supply, PoE is first disabled on port 48, followed by port 47 and, then port 2. Port 1 (with
the lowest interface number) takes precedence over all other ports and is disabled after all other ports are
disabled.
