Configuring the Hold-Time Interval After an Interface Goes Up/Down

When an interface frequently alternates between Up and Down, flapping may occur. To prevent the problem, you can configure the hold-time interval after an interface goes Up or Down. This command is supported only by the admin VS.

Procedure

Run system-view
The system view is displayed.
To configure the hold-time interval after the interface goes up or down globally, perform either of the following configurations as required.
- Run carrier up-hold-time interval
  
  The hold-time interval before the interface goes up is configured.
- Run carrier down-hold-time interval
  
  The hold-time interval before the interface goes down is configured.
When a non-default hold-time interval is configured on the interface, the interval configured on the interface takes effect. When the interface uses the default hold-time interval, the global configuration takes effect.
To set the hold-time interval value on a specified interface, run interface interface-type interface-number
The interface view is displayed.
Run either of the following commands as required.
- To configure the hold-time interval after an interface goes up, run the carrier up-hold-time interval command.
- To configure the hold-time interval after an interface goes down, run the carrier down-hold-time interval command.
Run commit
The configuration is committed.
