Usage Guidelines

When a fault occurs on a PIM (IPv6) network, use the display pim ipv6 invalid-packet command to check statistics and details about invalid PIM (IPv6) packets. The command output can help you locate the fault.

If PIM (IPv6) entries fail to be generated on a multicast network, you can run the display pim ipv6 invalid-packet command first to check whether devices have received invalid PIM (IPv6) messages. If the command output contains statistics about invalid PIM (IPv6) messages, run the display pim ipv6 invalid-packet [ packet-number ] verbose command to view details of invalid PIM (IPv6) messages to locate the fault.

You can run the following related commands to view information about specific invalid IPv6 PIM messages:

Run the display pim ipv6 invalid-packet command to view statistics about invalid IPv6 PIM messages received by a device in the public network instance.
Run the display pim ipv6 invalid-packet interface interface-type interface-number command to view statistics about invalid IPv6 PIM messages received by a specified interface.
Run the display pim ipv6 invalid-packet packet-number verbose command to view details of invalid IPv6 PIM messages recently received. Currently, details of a maximum of 100 invalid IPv6 PIM messages can be displayed.
