Masks for Access Control Lists
You must specify optional masks that control the order in which ACL
rules are checked. The switch includes two system default masks that pass/
filter packets matching the permit/deny rules specified in an ingress ACL.
You can also configure up to seven user-defined masks for an ACL. A
mask must be bound exclusively to one of the basic ACL types (i.e., Ingress
IP ACL, Egress IP ACL, Ingress MAC ACL or Egress MAC ACL), but a
mask can be bound to up to four ACLs of the same type.
