Multicast group policy does not work

Symptom

Hosts can receive multicast data from multicast groups that are not permitted by the multicast group policy.

Solution

To resolve the problem:

  1. Use the display acl command to verify that the configured ACL meets the multicast group policy requirements.

  2. Use the display this command in IGMP-snooping view or in a corresponding interface view to verify that the correct multicast group policy has been applied. If the applied multicast group policy is not correct, use the group-policy or igmp-snooping group-policy command to apply the correct multicast group policy.

  3. Use the display igmp-snooping command to verify that dropping unknown multicast data is enabled. If dropping unknown multicast data is not enabled, use the igmp-snooping drop-unknown command to enable dropping unknown multicast data.

  4. If the problem persists, contact Hewlett Packard Enterprise Support.
