Configuring Acl Masks; Specifying The Mask Type; Figure 3-50. Choosing Acl Types - Enterasys Matrix-V V2H124-24 Configuration Manual

Configuring ACL Masks

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 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.
Web – Click Security, ACL, ACL Mask Configuration. Click Edit for one of the basic
mask types to open the configuration page.
