21 Configuring Access Control Lists This chapter describes how to configure Access Control Lists (ACLs), including IPv4, IPv6, and MAC ACLs. This chapter also describes how to configure time ranges that can be applied to any of the ACL types. The topics covered in this chapter include: • ACL Overview • Configuring ACLs (Web) • Configuring ACLs (CLI) • ACL Configuration Examples ACL Overview Access Control Lists (ACLs) are a collection of permit and deny conditions, called rules, that provide security by blocking unauthorized users and allowing authorized users to access specific resources. ACLs can also provide traffic flow control, restrict contents of routing updates, and decide which types of traffic are forwarded or blocked. ACLs can reside in a firewall router, a router connecting two internal networks, or a Layer 3 switch, such as a PowerConnect 8000/8100-series switch. You can also create an ACL that limits access to the management interfaces based on the connection method (for example, Telnet or HTTP) and/or the source IP address. The PowerConnect 8000/8100-series switches support ACL configuration in both the ingress and egress direction. Egress ACLs provide the capability to implement security rules on the egress flows (traffic leaving a port) rather than the ingress flows (traffic entering a port). Ingress and egress ACLs can be applied to any physical port, port-channel (LAG), or VLAN routing port. Configuring Access Control Lists 513
