Chapter 12 Configuring Interface Characteristics
Configuring Ethernet Interfaces
To return to the default setting, use the no power inline consumption interface configuration command.
For information about the output of the show power inline consumption privileged EXEC command,
see the command reference for this release.
Configuring Power Policing
By default, the switch monitors the real-time power consumption of connected powered devices. You
can configure the switch to police the power usage. By default, policing is disabled.
For more information about the cutoff power value, the power consumption values that the switch uses,
and the actual power consumption value of the connected device, see the “Power Monitoring and Power
Policing” section in the “Configuring Interface Characteristics” chapter of the software configuration
guide for this release.
Beginning in privileged EXEC mode, follow these steps to enable policing of the real-time power
consumption of a powered device connected to a PoE port:
Step 4 power inline consumption wattage
or
power inline port maximum_wattage
Configure the power consumption of a powered device connected to a
PoE port on the switch. The range for each device is 4000 to 15400 mW.
The default is 15400 mW.
Configure enhanced PoE to increase the maximum power supplied to a
device (up to 20 W).
Step 5
end Return to privileged EXEC mode.
Step 6 show power inline consumption Display the power consumption data.
Step 7 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the physical port to be configured, and enter interface
configuration mode.
Step 3
power inline police [ action log ] If the real-time power consumption exceeds the maximum power
allocation on the port, configure the switch to take one of these actions:
•
Shut down the PoE port, turn off power to it, and put it in the
error-dsabled state—Enter the
power inline police command.
Note You can enable error detection for the PoE error-disabled cause
by using the
errdisable detect cause inline-power global
configuration command. You can also enable the timer to recover
from the PoE error-disabled state by using the
errdisable
recovery cause inline-power interval interval global
configuration command.
• Generate a syslog message while still providing power to the
port—Enter the
power inline police action log command.
If you do not enter the action log keywords, the default action shuts down
the port and puts the port in the error-disabled state.
