ACCESS CONTROL LISTS

Command Usage

The following restrictions apply to ACLs:

•Each ACL can have up to 32 rules.

•The maximum number of ACLs is also 32.

•However, due to resource restrictions, the average number of rules bound to the ports should not exceed 20.

•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.

•When an ACL is bound to an interface as an egress filter, all entries in the ACL must be deny rules. Otherwise, the bind operation will fail.

•The switch does not support the explicit “deny any any” rule for the egress IP ACL or the egress MAC ACLs. If these rules are included in ACL, and you attempt to bind the ACL to an interface for egress checking, the bind operation will fail.

The order in which active ACLs are checked is as follows:

1.User-defined rules in the Egress MAC ACL for egress ports.

2.User-defined rules in the Egress IP ACL for egress ports.

3.User-defined rules in the Ingress MAC ACL for ingress ports.

4.User-defined rules in the Ingress IP ACL for ingress ports.

5.Explicit default rule (permit any any) in the ingress IP ACL for ingress ports.

6.Explicit default rule (permit any any) in the ingress MAC ACL for ingress ports.

7.If no explicit rule is matched, the implicit default is permit all.
