VLAN-based Multicast Group Policy Does Not Take Effect

Fault Description

A multicast policy is configured on the switch to allow hosts to join specified multicast groups. However, hosts can still receive multicast data sent to other multicast groups.

Procedure

  1. Run the display acl command to check whether the access control list (ACL) rules conflict with the multicast group policy.
  2. Run the display igmp-snooping configuration command to check whether a correct multicast group policy is applied to the VLAN. If not, run the igmp-snooping group-policy command to apply a correct multicast group policy to the VLAN.
  3. Run the display current-configuration | include drop-unknown command to check whether the switch is enabled to discard unknown multicast packets. If not, run the multicast drop-unknown command to enable the switch to discard unknown multicast packets.
