How does an S series switch process packets when Layer 2 multicast references an ACL

In Layer 2 multicast, three functions need to reference the ACL. After an ACL is referenced, packets are processed based on ACL rules. If no rule is configured, packets are processed as follows:
- IGMP snooping group policy: In V200R001 and earlier versions, the default rule is permit. In V200R002 and later versions, if default-permit is not configured, the default rule is deny; if default-permit is configured, the default rule is permit.
- IGMP snooping prompt leave: In V200R001 and earlier versions, the default rule is permit. In V200R002 and later versions, if default-permit is not configured, the default rule is deny; if default-permit is configured, the default rule is permit.
- IGMP snooping SSM policy: The default rule is deny.
