Function

Using the port-down holdoff-timer command, you can set the delay in reporting a port status change event.

Format

port-down holdoff-timer interval

Parameters

Parameter	Description	Value
interval	Specifies the delay timer.	The value is an integer. The value can be 0 or in the range of 50 to 50000, in milliseconds.

Views

GE interface view, XGE interface view

Default Level

2: Configuration level

Usage Guidelines

Usage Scenario

When the cable connected to an interface is faulty, the interface status may change frequently. When this occurs, the system frequently updates the matching entries. If link backup is configured on the interface, active/standby switchovers occur frequently. To prevent frequent status change, you can use the port-down holdoff-timer command to set the delay in reporting a port status change event.

If an interface is connected to a wavelength division multiplexing device, the interface becomes Down when a protective switchover occurs on the wavelength division multiplexing device, and services are interrupted. To prevent service interruption, you can set the delay in reporting a port Down event.

Configuration Impact

If you run the port-down holdoff-timer command multiple times in the same interface view, only the latest configuration takes effect.

It is replaced by the carrier { up-hold-time | down-hold-time } interval command.

Example

# Set the delay in reporting a port status change event to 1000 milliseconds on GigabitEthernet0/0/1.
