Moxa Managed Ethernet Switch (UI_2.0_FW_5.x) User Manual
Include Unknown Unicast Packet
When checked, the switch will discard Unknown Unicast packets if the Unknown Unicast packet traffic is
over the limit.
NOTE
For the EDS-510E, IKS-G6000A, and ICS-G7000A Series, you can use "Rate Limiting" to limit the
broadcast traffic in order to prevent traffic storm. Please refer to the "Rate Limiting" section f or f urther
details.
Loop Protection
The switch is designed with a loop checking mechanism whereby it sends a control BPDU f rom the Ethernet
port and check if this control PBDU will be sent back to the switch again. If the looping occurs, the switch
will automatically block the Ethernet port to prevent looping.

Access Control List
NOTE
Access Control Lists are available in Moxa Layer 3 switches and the f ollowing layer 2 switches: EDS-518E,
EDS-528E, EDS-G508E, EDS-G512E, EDS-G516E, EDS-G512E-8PoE, the IKS Series, and the ICS Series.
Layer 2 switches only support Ingress ACL.
Access control lists (ACLs) increase the f lexibility and security of networking management. ACLs provide
traf f ic f iltering capabilities f or ingress and egress packets. Moxa ACLs can manage f ilter criteria f or 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 conf iguration interf ace is easy to
use. Users can quickly establish f iltering 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.
