Netgear GSM7224v2 - 24-Port Layer 2 Managed Gigabit Switch User Manual

Configuring Access Control Lists

Access Control Lists (ACLs) ensure that only authorized users have access to specific 
resources while blocking off any unwarranted attempts to reach network resources. ACLs are 
used to provide traffic flow control, restrict contents of routing updates, decide which types of 
traffic are forwarded or blocked, and above all provide security for the network. ProSafe® 
Managed Switches software supports IPv4 and MAC ACLs.

You first create an IPv4-based or MAC-based ACL ID. Then, you create a rule and assign it 
to a unique ACL ID. Next, you define the rules, which can identify protocols, source, and 
destination IP and MAC addresses, and other packet-matching criteria. Finally, use the ID 
number to assign the ACL to a port or to a LAG.

A MAC ACL consists of a set of rules which are matched sequentially against a packet. When 
a packet meets the match criteria of a rule, the specified rule action (Permit/Deny) is taken 
and the additional rules are not checked for a match. On this menu the interfaces to which an 
MAC ACL applies must be specified, as well as whether it applies to inbound or outbound 
traffic. Rules for the MAC ACL are specified/created using the MAC ACL Rule Configuration 
menu.

There are multiple steps involved in defining a MAC ACL and applying it to the switch:
