Vlan Preclassification

The following scenario shows how to pre-classify packets using traffic policies. This reduces packet processing time and improves system performance.

Test VLAN Pre-Classify Out (802.1Q)

Description

A traffic policy is configured in DUT0 (interface eth0). This policy enables vlan pre-classification in the link-out hook; i.e., all packets leaving this interface are processed. Traffic policy is responsible of setting the class Id for traffic control in egress. Traffic selector filter based on ethernet protocol (802.1Q) and VLAN Id (100).
