Ip Acls - Cisco Nexus 5000 Series Configuration Manual

Overview

IP ACLs

IP ACLs
IP ACLs are ordered sets of rules that you can use to filter traffic based on IPv4 information in the Layer 3
header of packets. Each rule specifies a set of conditions that a packet must satisfy to match the rule. When
the Cisco NX-OS software determines that an IP ACL applies to a packet, it tests the packet against the
conditions of all rules. The first match determines whether a packet is permitted or denied, or if there is no
match, the Cisco NX-OS software applies the applicable default rule. The Cisco NX-OS software continues
processing packets that are permitted and drops packets that are denied.
