Figure 1-4 Policing and Marking Flowchart on Physical Ports
Policing on SVIs
Note Before configuring a hierarchical policy map with individual policers on an SVI, you must enable
VLAN-based QoS on the physical ports that belong to the SVI. Though a policy map is attached to the
SVI, the individual policers only affect traffic on the physical ports specified in the secondary interface
level of the hierarchical policy map.
A hierarchical policy map has two levels. The first level, the VLAN level, specifies the actions to be
taken against a traffic flow on an SVI. The second level, the interface level, specifies the actions to be
taken against the traffic on the physical ports that belong to the SVI and are specified in the
interface-level policy map.
