IP access control lists – ACLs are used by routers to deny or forward specific traffic from passing through some network interface. We can say that ACLs are used when traffic travels from one network address space to other. Cisco Catalyst switch can also have an ACL applied within a VLAN. This special kind of ACL is called a VLAN access control list – VACL.
