Usage Guidelines

Usage Scenario

To view statistics and details of invalid PIM messages, run the display pim invalid-packet command. The command output helps you locate and rectify faults.

If PIM entries fail to be generated on a multicast network, you can run the display pim invalid-packet command first to check whether devices have received invalid PIM messages. If the command output contains statistics about invalid PIM messages, run the display pim invalid-packet verbose command to view details of invalid PIM messages to locate faults.

If interface interface-type interface-number is specified, the command displays statistics about invalid PIM messages received by the specified interface.

Example

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

# Display statistics about invalid PIM messages received in the public network instance.
