Chapter 12 Configuring Interface Characteristics
Configuring Ethernet Interfaces
To disable policing of the real-time power consumption, use the
no power inline police
interface
configuration command. To disable error recovery for PoE error-disabled cause, use the
no errdisable
recovery cause inline-power
global configuration command.
For information about the output from the
show power inline police
privileged EXEC command, see
the command reference for this release.
Adding a Description for an Interface
You can add a description about an interface to help you remember its function. The description appears
in the output of these privileged EXEC commands:
show configuration
,
show running-config
,
and
show interfaces
.
Step 3

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.
Step 4
exit
Return to global configuration mode.
Step 5
errdisable detect cause inline-power
and
errdisable recovery cause inline-power
and
errdisable recovery interval
interval
(Optional) Enable error recovery from the PoE error-disabled state, and
configure the PoE recover mechanism variables.
For
interval
interval
, specify the time in seconds to recover from the
error-disabled state. The range is 30 to 86400.
By default, the recovery interval is 300 seconds.
Step 6
exit
Return to privileged EXEC mode.
Step 7
show power inline police
show errdisable recovery
Display the power monitoring status, and verify the error recovery
settings.
Step 8
copy running-config startup-config
(Optional) Save your entries in the configuration file.
