Assign an IP ACL to an Interface c s Ingress IP ACLs are supported on platforms: and e s Ingress and Egress IP ACL are supported on platform: To pass traffic through a configured IP ACL, you must assign that ACL to a physical interface, a port channel interface, or a VLAN. The IP ACL is applied to all traffic entering a physical or port channel interface and the traffic is either forwarded or dropped depending on the criteria and actions specified in the ACL. The same ACL may be applied to different interfaces and that changes its functionality. For example, you can take ACL "ABCD", and apply it using the in keyword and it becomes an ingress access list. If you apply the same ACL using the out keyword, it becomes an egress access list. If you apply the same ACL to the loopback interface, it becomes a loopback access list. This chapter covers the following topics: • Configuring Ingress ACLs • Configuring Egress ACLs • Configuring ACLs to Loopback For more information on Layer-3 interfaces, refer to Chapter 13, Interfaces, on page 47. To apply an IP ACL (standard or extended) to a physical or port channel interface, use these commands in the following sequence in the INTERFACE mode: Step Command Syntax 1 interface interface slot/port 2 ip address ip-address 3 ip access-group access-list-name {in | out} [implicit-permit] [vlan vlan-range] 4 ip access-list [standard | extended] name Command Mode CONFIGURATION INTERFACE INTERFACE INTERFACE Purpose Enter the interface number. Configure an IP address for the interface, placing it in Layer-3 mode. Apply an IP ACL to traffic entering or exiting an interface. • out: configure the ACL to filter outgoing traffic. This keyword is supported only on E-Series. Note: The number of entries allowed per ACL is hardware-dependent. Refer to your line card documentation for detailed specification on entries allowed per ACL. Apply rules to the new ACL. IP Access Control Lists (ACL), Prefix Lists, and Route-maps | 145
