Configuring packet filtering on an interface

When an ACL is applied to an interface, the time range-based filtering will also work at the same time.
In addition, you can specify separate access rules for inbound and outbound packets.
The effective range for basic ACL numbers is 2000 to 2999. A basic ACL defines rules based on the
Layer 3 source IP addresses only to analyze and process data packets.
The effective range for advanced ACL numbers is 3000 to 3999. An advanced ACL defines rules
according to the source and destination IP addresses of packets, the type of protocol over IP, TCP/UDP
source and destination ports, and so on.
You cannot enable packet filtering on an aggregation member port. You cannot add an interface with
packet filtering enabled to an aggregation group.
