6.2 ACL
The LGB5028A or LGB5052A switch access control list (ACL) is probably the most commonly used object in the IOS. It is used not
only for packet filtering, but also for selecting types of traffic to be analyzed, forwarded, or influenced in some way. The ACLs are
divided into EtherTypes, IPv4, ARP protocol, MAC, and VLAN parameters, etc. Here we will just go over the standard and
extended access lists for TCP/IP. As you create access control entries (ACEs) for ingress classification, you can assign a policy for
each port, (the policy number is 1–8), however, each policy can be applied to any port. This makes it very easy to determine what
type of ACL policy you will be working with.
6.2.1 Ports
The section describes how to configure the ACL parameters (ACE) of each switch port.
These parameters will affect frames received on a port unless the frame matches a specific ACE.
Web Interface
To configure the ACL Ports Configuration in the Web interface:
1. Click “Configuration,” “ACL,” then “Ports.”
2. Scroll to the specific parameter value to select the correct value for port ACL setting.
3. Click “Save.”
4. To cancel the setting, click the “Reset” button. It will revert to previously saved values.
5. When configuration is complete, you will see the port counter. Click “Refresh” to update the counter or “Clear” to clear the
information.
