Use the Access Control List Interface Summary page to associate an ACL (Access Control List), or multiple ACLs, with one or more interfaces on the device. When an ACL is associated with an interface, traffic on the port is checked against the rules defined within the ACL until a match is found. If the traffic does not match any rules within an ACL, it is dropped because of the implicit deny all rule at the end of each ACL.

Access Control List Interface Summary Fields
| Field | Description |
|---|---|
| Interface | The interface that has an associated ACL. |
| Direction | Whether the packet is checked against the rules in an ACL when it is received on an interface (Inbound) or after it has been received, routed, and is ready to exit an interface (Outbound). |
| Sequence Number | The order the ACL is applied to traffic on the interface relative to other ACLs associated with the interface in the same direction. When multiple ACLs are applied to the same interface in the same direction, the ACL with the lowest sequence number is applied first, and the other ACLs are applied in ascending numerical order. |
| ACL Type | The type of ACL, which is either IPv4, IPv6, or MAC. |
| ACL Identifier | The name or number that identifies the ACL. When applying an ACL to an interface, the ACL Identifier menu includes only the ACLs within the selected ACL Type. |
