Command History
Usage Guidelines Only one policy map per ingress port is supported.
Policy maps can be configured on physical ports or on SVIs. When VLAN-based quality of service
(QoS) is disabled by using the no mls qos vlan-based interface configuration command on a physical
port, you can configure a port-based policy map on the port. If VLAN-based QoS is enabled by using
the mls qos vlan-based interface configuration command on a physical port, the switch removes the
previously configured port-based policy map. After a hierarchical policy map is configured and applied
on an SVI, the interface-level policy map takes effect on the interface.
You can apply a policy map to incoming traffic on a physical port or on an SVI. You can configure
different interface-level policy maps for each class defined in the VLAN-level policy map. For more
information about hierarchical policy maps, see the “Configuring QoS” chapter in the software
configuration guide for this release.
Classification using a port trust state (for example, mls qos trust [cos | dscp | ip-precedence] and a
policy map (for example, service-policy input policy-map-name) are mutually exclusive. The last one
configured overwrites the previous configuration.
input policy-map-name Apply the specified policy map to the input of a physical port or an SVI.
