3 Configuring the Switch

Access Control Lists

Access Control Lists (ACL) provide packet filtering for IP frames (based on address, protocol, Layer 4 protocol port number or TCP control code) or any frames (based on MAC address or Ethernet type). To filter incoming packets, first create an access list, add the required rules and then bind the list to a specific port.

Configuring Access Control Lists

An ACL is a sequential list of permit or deny conditions that apply to IP addresses, MAC addresses, or other more specific criteria. This switch tests ingress or egress packets against the conditions in an ACL one by one. A packet will be accepted as soon as it matches a permit rule, or dropped as soon as it matches a deny rule. If no rules match for a list of all permit rules, the packet is dropped; and if no rules match for a list of all deny rules, the packet is accepted.

Command Usage

The following restrictions apply to ACLs:

•Each ACL can have up to 32 rules.

•The maximum number of ACLs is 88.

•However, due to resource restrictions, the average number of rules bound to the ports should not exceed 20.

•This switch supports ACLs for ingress filtering only. However, you can only bind one IP ACL to any port and one MAC ACL globally for ingress filtering. In other words, only two ACLs can be bound to an interface - Ingress IP ACL and Ingress

MAC ACL.
