Traffic Filtering Overview
You can filter in or filter out a class of traffic by associating the class with a traffic filtering action. For
example, you can filter packets sourced from a specific IP address according to network status. By
using ACL rules configured with a time range for traffic classification, you can implement time-based
traffic filtering.
Alternatively, you can implement traffic filtering on a port by directly applying an ACL on the port. For the
configuration procedure, refer to ACL Configuration in the Security Volume.
