Chapter 11 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.
Beginning in privileged EXEC mode, follow these steps to add a description for an interface:
Use the no description interface configuration command to delete the description.
This example shows how to add a description on a port and how to verify the description:
Switch# config terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)# interface gigabitethernet1/0/2
Switch(config-if)# description Connects to Marketing
Switch(config-if)# end
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.
By default, the recovery interval is 300 seconds.
For interval interval, specify the time in seconds to recover from the
error-disabled state. The range is 30 to 86400.
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.
