Chapter 4 Flow Template Configuration
4.1 Flow Template Overview
Flow templates are mainly used to limit the information included in the ACL rules. For
an ACL rule to be successfully applied on a port, the information in the rule must be a
subset of the information defined in the flow template applied on the port. For example,
the flow template applied on a port defines source IP address, destination IP address,
source TCP port, and destination TCP port. Then only the ACL rules that contain no
other information items than the above ones can be applied correctly on the port for
packet filtering, QoS and other purposes.
The switch supports both default flow template and user-defined flow templates. And,
the user-defined flow templates can be classified into two types: basic and extended.
Initially, if you do not reference any flow template on a port, the default one is used.
A flow template is configured globally and applied on a port.
Caution:
The use of flow templates is restricted to hardware-based ACL.
4.2 Configuring a Flow Template
Follow these steps to create a flow template and apply it to an interface:
