Configuring the Maximum Number of Invalid IPv6 Multicast Protocol Packets that a Device Can Store

Configuring the Maximum Number of Invalid IPv6 Multicast Protocol Packets that a Device Can Store

This section describes how to configure the maximum number of invalid IPv6 multicast protocol packets that a device can store. This configuration helps locate and rectify faults.

Applicable Environment

If multicast forwarding entries cannot be established on a network, you can configure the maximum number of invalid IPv6 multicast protocol packets that the devices can store. Then you can check statistics and detailed information about invalid multicast protocol packets using related commands to troubleshoot problems.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run multicast ipv6 invalid-packet { mld | pim } max-count max-number

    The maximum number of invalid IPv6 multicast protocol packets that the device can store is configured.

  3. Run commit

    The configuration is committed.

Checking the Configuration

Run the display current-configuration | include multicast ipv6 invalid-packet command to check the maximum number of invalid IPv6 multicast protocol packets that the device can store.

<HUAWEI> display current-configuration | include multicast ipv6 invalid-packet
 multicast ipv6 invalid-packet mld max-count 20

To check statistics about invalid IPv6 multicast protocol packets that the device stores, perform the following operations:

  • Run the display mld invalid-packet [ interface interface-type interface-number | message-type { done | query | report } ] * command to check statistics about invalid multicast listener discovery (MLD) packets that the device stores.

    <HUAWEI> display mld invalid-packet
    
             Statistics of invalid packets for public net:

  • Run the display pim ipv6 invalid-packet [ interface interface-type interface-number | message-type { assert | bsr | hello | join-prune | graft | graft-ack | state-refresh } ] * command to check statistics about invalid IPv6 Protocol Independent Multicast (PIM) packets that the device stores.
