Chapter36 Configuring QoS Understanding QoS
When configuring policing on an SVI, you can create and conf igure a hierarch ical po licy m ap with t hese
two levels:
VLAN level—Create this primary level by configuring class maps and classes that specify the port
trust state or set a new DSCP or IP precedence value in the packet. The VLAN-level policy map
applies only to the VLAN in an SVI and does not support polic er s.
Interface level—Create this secondary level by configuring class maps and classes that specify the
individual policers on physical ports the belong to the SVI. The interface-level policy map only
supports individual policers and does not support aggregate policers. You can configure different
interface-level policy maps for each class defined in the VLAN-level policy map.
See the “Classifying, Policing, and Marking Traffic on SVIs by Using Hierarchica l Policy Maps ” section
on page 36-52 for an example of a hierarchical policy map.
Figure 36-5 shows the policing and marking process when hierarchical policy maps on an SVI.
