SMC Networks SMC6824M manual Setting the ACL Name and Type, Command Attributes

ACCESS CONTROL LISTS

•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.

Setting the ACL Name and Type

Use the ACL Configuration page to designate the name and type of an ACL.

Command Attributes

•Name – Name of the ACL. (Maximum length: 15 characters)

•Type – There are three filtering modes:

-Standard: IP ACL mode that filters packets based on the source IP address.

-Extended: IP ACL mode that filters packets based on source or destination IP address, as well as protocol type and protocol port number. If the “TCP” protocol is specified, then you can also filter packets based on the TCP control code.

-MAC: MAC ACL mode that filters packets based on the source or destination MAC address and the Ethernet frame type (RFC 1060).
