CLI – This rule permits packets from any source MAC address to the
destination address 00-e0-29-94-34-de where the Ethernet type is 0800.

Configuring ACL Masks

You must specify 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
must also configure up to seven user-defined masks for an ingress or
egress 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.

Command Usage

Up to seven entries can be assigned to an ACL mask.

Packets crossing a port are checked against all the rules in the ACL
until a match is found. The order in which these packets are checked is
determined by the mask, and not the order in which the ACL rules are
entered.

First create the required ACLs and the ingress or egress masks before
mapping an ACL to an interface.

You must configure a mask for an ACL rule before you can bind it to
a port or set the queue or frame priorities associated with the rule.

Specifying the Mask Type

Use the ACL Mask Configuration page to edit the mask for the Ingress IP
ACL, Egress IP ACL, Ingress MAC ACL or Egress MAC ACL.
