Quality of Service (QoS): Managing Bandwidth More Effectively
Introduction
| Classifiers for Prioritizing Outbound Packets |
|
|
N o t e O n U s i n g | ProCurve recommends that you configure a minimum number of the available |
M u l t i p l e | QoS classifiers for prioritizing any given packet type. Increasing the number |
C r i t e r i a | of active classifier options for a packet type increases the complexity of the |

| Packet Classifiers and Evaluation Order |
| |
| The switches covered in this guide provide the following QoS classifiers |
| (packet criteria) you can use to configure QoS priority. |

Search Precedence QoS Classifier Type
Order
11 (highest) IP Type of Service (ToS) field (IP packets only)
22 Incoming
33 (lowest) Incoming 802.1p Priority (present in tagged VLAN environments)
Where multiple classifier types are configured, a switch uses the
Note that on the switches covered in this guide, if the switch is configured with multiple classifiers that address the same packet, the switch uses only the QoS configuration for the QoS classifier that has the highest precedence. In this case, the QoS configuration for another,
