Usage Guidelines

If a switch fails to create PIM entries, you can run the display pim invalid-packet command first to check whether the switch has received invalid PIM messages. If the command output displays counters of invalid PIM messages, run the display pim invalid-packet [ packet-number ] verbose command to view details of invalid PIM messages for fault location.

You can run the following commands to view information about specific invalid PIM messages:

Run the display pim [ vpn-instance vpn-instance-name | all-instance ] invalid-packet command to view statistics about invalid PIM messages received in a specified VPN instance or in all VPN instances.
Run the display pim invalid-packet interface interface-type interface-number command to view statistics about invalid PIM messages received by a specified interface.
Run the display pim invalid-packet packet-number verbose command to view details of invalid PIM messages recently received. Currently, details of a maximum of 100 invalid PIM messages can be displayed.
