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:
Use the display acl command to verify that the configured ACL meets the multicast group policy requirements.
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.
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.
If the problem persists, contact Hewlett Packard Enterprise Support.
