Configuring the Maximum Number of Invalid IPv4 Multicast Protocol Packets that a Device Can Store

Configuring the Maximum Number of Invalid IPv4 Multicast Protocol Packets that a Device Can Store

This section describes how to configure the maximum number of invalid ipv4 multicast protocol packets that a device can store. This configuration helps locate and rectify faults.

Applicable Environment

If multicast forwarding entries or Multicast Source Discovery Protocol (MSDP) peer relationships cannot be established on a network, you can configure the maximum number of invalid multicast protocol packets that the devices can store. Then you can check statistics and details about invalid multicast packets using related commands for troubleshooting.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run multicast invalid-packet { igmp | mdt | msdp | pim } max-count max-number

    The maximum number of invalid 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 invalid-packet command to check the maximum number of invalid multicast protocol packets that the device can store.

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

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

  • Run the display igmp [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ interface interface-type interface-number | message-type { leave | query | report } ] * command to check statistics about invalid Internet Group Management Protocol (IGMP) packets that the device stores.

    <HUAWEI> display igmp invalid-packet
    
               Statistics of invalid packets for public net:
    --------------------------------------------------------------------
    IGMP Query invalid packet:

  • Run the display msdp [ vpn-instance vpn-instance-name | all-instance ] invalid-packet [ peer peer-address | message-type { keepalive | notification | sa-request | sa-response | source-active } ] * command to check statistics about invalid MSDP packets that the device stores.
