Classifier policies overview
Classifier policies let a network administrator define sets of rules based on network traffic addressing or other header content, and use these rules to restrict or alter the passage of traffic through the switch. Choosing the rule criteria is called Classification, and one such rule, or list, is called a policy.
Frame ingress VLAN ID
Source and/or destination Ethernet MAC, IPv4, or IPv6 address
Layer 2 (EtherType) and Layer 3 (IP) protocol
Layer 4 application ports
A policy contains one or more policy entries, which are listed according to priority by sequence number. A single policy entry contains a class and corresponding policy action. Policy action is taken on traffic matched by its corresponding class.
A policy can be applied to an individual front plane port, or a Link Aggregation Group (LAG) interface.
