Access Control List

NOTE

Access Control Lists are available in

Moxa Layer 3 switches and the following layer 2 switches: EDS-528E,

EDS

-518E. EDS-G508E, EDS-G512E, EDS-G516E, and EDS-G512E-8PoE. Layer 2 switches only support

Ingress ACL.

Access control lists (ACLs) increase the flexibility and security of networking management. ACLs provide traffic

filtering capabilities for ingress and egress packets. Moxa ACLs can manage filter criteria for a diverse range of

protocols and allow users to configure customized filter criteria. For example, users can deny access to specific

source or destination IP/MAC addresses. The Moxa ACL configuration interface is easy to use. Users can quickly

establish filtering rules, manage rule priorities, and view overall settings on the display page.

The ACL Concept

What is ACL?

An access control list is a basic traffic filter for ingress and egress packets. The ACL can examine each Ethernet

packet’s information and take the necessary action. Moxa Layer 3 switches provide complete filtering

capabilities. Access list criteria could include the source or destination IP address of the packets, the source or

destination MAC address of the packets, IP protocols, or other information. The ACL can check these criteria to

decide whether to permit or deny access to a packet.

Benefits of ACL

ACLs support per interface, per packet direction, and per protocol filtering capability. These features can

provide basic protection by filtering specific packets. The main benefits of an ACL are:

• Manage authority of hosts: An ACL can restrict specific devices through MAC address filtering. The user

can deny all packets or only permit packets that come from specific devices.

• Subnet authority management: Configure filtering rules for specific subnet IP addresses. An ACL can

restrict packets from or to specific subnets.

• Network security: The demand for networking security is growing. An ACL can provide basic protection

that works in a similar manner to an Ethernet firewall device.

• Control traffic flow by filtering specific protocols: An ACL can filter specific IP protocols such as TCP or

UDP packets.
