timer spt-switch (IPv4)

Function

The timer spt-switch command sets the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from the RPT to the SPT.

The undo timer spt-switch command restores the default value of the interval.

By default, the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from the RPT to the SPT is 15 seconds.

Format

timer spt-switch interval

undo timer spt-switch

Parameters

Parameter	Description	Value
interval	Specifies the interval for checking whether the rate for transmitting multicast data exceeds the threshold before the switchover from RPT to SPT.	The value is an integer that ranges from 15 to 65535, in seconds.

Usage Guidelines

Usage Scenario

You can run the timer spt-switch command to set the interval for checking whether the rate for transmitting multicast data exceeds the threshold.

Prerequisites

IP multicast routing has been enabled using the multicast routing-enable command.

Precautions

This command is valid for only PIM-SM.

Before running this command, you must set the threshold for SPT switchover by using the spt-switch-threshold (IPv4) command; otherwise, the timer spt-switch command takes no effect.

Example

# In the PIM view of public network instance, set the interval for checking the rate for transmitting the multicast data before the switchover from RPT to SPT to 30 seconds.
