Application Order
When the device processes a packet, it determines the forwarding path of the packet. The path determines
which ACLs that the device applies to the traffic. The device applies the ACLs in the following order:
1
Port ACL
2
Ingress Router ACL
Rules
You can create rules in access-list configuration mode by using the permit or deny command. The switch
allows traffic that matches the criteria in a permit rule and blocks traffic that matches the criteria in a deny
rule. You have many options for configuring the criteria that traffic must meet in order to match the rule.
