Note: If an interface is configured as a vlan-stack access port, the packets are filtered by an L2 ACL only.
The L3 ACL applied to such a port does not affect traffic. That is, existing rules for other features (such as
trace-list, PBR, and QoS) are applied accordingly to the permitted traffic.
For information on MAC ACLs, refer to

Assign an IP ACL to an Interface

Ingress IP ACLs are supported on platforms:
Ingress and Egress IP ACLs 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
apply the same ACL using the
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 Interfaces.
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:
