Configuring IP ACLs

IP ACLs classify for Layer 3.
Each ACL is a set of up to ten rules applied to inbound traffic. Each rule specifies whether the
contents of a given field should be used to permit or deny access to the network, and may apply to
one or more of the following fields within a packet:
• Source IP address
• Destination IP address
• Source Layer 4 port
• Destination Layer 4 port
• TOS byte
• Protocol number
Note that the order of the rules is important: when a packet matches multiple rules, the first rule
takes precedence. Also, once you define an ACL for a given port, all traffic not specifically
permitted by the ACL will be denied access.
