display control-flap

Function

The display control-flap command displays the running status and statistics of control-flap on an interface. You can adjust parameters about control-flap based on the statistics.

If no interface is specified, the running status and statistics of control-flap on all interfaces are displayed.

Format

display control-flap [ interface { interface-name | interface-type interface-number } ]

Parameters

Parameter	Description	Value
interface-name	Specifies the name of an interface.	-
interface-type	Specifies the type of an interface.	-
interface-number	Specifies the number of an interface.	The value is a string of 1 to 63 case-sensitive characters, spaces not supported.

Usage Guidelines

Usage Scenario

Before you monitor interface status or locate an interface fault, run the display control-flap command to view the running status and statistics of control-flap on the interface. The command output helps you adjust control-flap parameters, collect traffic statistics, and troubleshoot the interface.

Configuration Impact

If interface-type interface-number is not specified, the running status and statistics of control-flap on all interfaces are displayed.

Follow-up Procedure

If you find that the parameters about control-flap are not proper based on the output of the display control-flap command, adjust the parameters by using the control-flap command.

Example

The actual command output varies according to the device. The command output here is only an example.
