Usage Guidelines

Usage Scenario

To locate the device on which a fault occurs, you can run the display multicast flow-statistic command to check real-time multicast traffic statistics on each device on a multicast traffic forwarding path.

Precautions

The command may fail to display multicast traffic statistics or fail to display multicast traffic statistics completely in any of the following situations:

If the specified VLAN IDs and traffic direction is consistent with those in the traffic policy configured on the device, statistics about the multicast traffic matching the traffic policy are not displayed.
If the specified Trunk interface does not have member interfaces, real-time statistics on the Trunk interface fail to be displayed.
If the specified interface is an interface on the user side, real-time multicast statistics on the interface fail to be displayed.
Real-time multicast statistics fails to be displayed during the period between two statistics collecting times.

Example

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