Applying an ACL to the Switch

Applying an ACL to the Switch


An ACL is a set of rules that differentiate packets and determine whether packets are permitted and denied. The device then processes the permitted packets and discards the denied packets.


  • Apply ACLs.

    ACLs can be applied to many features. For example, to process different types of traffic, you can use basic ACLs, basic ACL6s, advanced ACLs, advanced ACL6s, Layer 2 ACLs, or user-defined ACLs to perform traffic policing or traffic classification on the traffic that matches the ACL rules.

    • ACLs can be applied to different services, and devices running these services process the classified packets based on service requirements. For details about the services referencing ACLs, see the configuration guide.
    • On the switches except CE6870EI and CE6875EI, during ACL application, TRILL, FCoE, and traffic policy use the same module. If the system prompts insufficient resources when all these features are configured, you need to adjust service configurations to ensure successful service delivery.
