Parameters

Parameter Name Parameter Meaning
VlanId Indicates a VLAN ID.
SourceIp Indicates a source IP address.
GroupIp Indicates a group IP address.

Possible Causes

The number of multicast forwarding entries has reached the upper limit.

Procedure

  1. Run the display multicast forwarding-table command to check the Layer 3 forwarding table or run the display l2-multicast forwarding-table command to check Layer 2 multicast forwarding table. Determine whether the number of multicast entries exceeds the product specification. For the product specifications, log in to Huawei official website to download the product brochure.

    • If yes, go to step 2.
    • If no, the index resource application may have failed. Go to step 3.

  2. Run the reset multicast forwarding-table [ group-address | source-address ] command to delete redundant Layer 3 multicast forwarding entries. Or run the reset igmp-snooping group vlan [ vlan-id ] group-address [ group-address ] command to delete redundant Layer 2 multicast forwarding entries. Then re-configure multicast services. If this log persists, go to step 3.
  3. Collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
