24-Port 10/100 + 2-Port Gigabit Switch with Webview and Power over Ethernet 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. Click Submit to save the changes. Figure 5-43: Security - ACL Port Binding 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. 60 Chapter 5: Configuring the Switch through the Web Utility Security
