If a packet matches multiple rules in these ACLs and ispermitted by some rules but denied by the others, the device permits or denies the packet based on therule in the ACL with the highest priority.Assigning an ACL GloballyConfiguration prerequisitesBefore applying ACL rules to a VLAN, you need to define the related ACLs. For information aboutdefining an ACL, refer to section Configuring Basic ACL, section Configuring Advanced ACL, sectionConfiguring Layer 2 ACL.Configure procedureTable 1-5 Assign an ACL globallyOperation Command DescriptionEnter system view system-view —
