ACL Port Binding
After configuring Access Control Lists (ACL), you should bind them to the ports that need to filter traffic. You can
assign one IP access list to any port, but you can only assign one MAC access list to all the ports on the switch.
You must configure a mask for an ACL rule before you can bind it to a port.
This switch only supports ACLs for ingress filtering. You can only bind one IP ACL to any port, and one MAC ACL
globally, for ingress filtering.
Mark the Enable checkbox for the port you want to bind to an ACL. Select the required ACL from the drop-down
menu.
Port – Fixed port or SFP module. (Range: 1-26)
IP. Specifies the IP Access List to enable for a port.
MAC. Specifies the MAC Access List to enable globally.
IN. ACL for ingress packets.
ACL Name. Name of the ACL.

802.1xUsers
Network switches can provide open and easy access to network resources by simply attaching a client PC.
Although this automatic configuration and access is a desirable feature, it also allows unauthorized personnel to
easily intrude and possibly gain access to sensitive network data.
The IEEE 802.1X (dot1X) standard defines a port-based access control procedure that prevents unauthorized
access to a network by requiring users to first submit credentials for authentication. Access to all switch ports in
a network can be centrally controlled from a server, which means that authorized users can use the same
credentials for authentication from any point within the network.
