HP-UX IPQoS A.01.00 Administrator's Guide (October 2005)

Introduction
HP-UX IPQoS Features
Chapter 126
HP-UX IPQoS provides provisioned QoS only. Signaled QoS is not supported.
• Supports both IPv4 and IPv6
HP-UX IPQoS can filter on IPv4 and IPv6 addresses. (For IPv6 addresses to be
meaningful, you must to be running on an IPv6-enabled system.)
• Provides a simple configuration file format
HP-UX IPQoS configuration files are in text format and use a simple syntax. They can be
created and maintained using any common HP-UX text editor, such as vi.
• Provides a single simple utility for all administrative tasks
HP-UX IPQoS provides one inclusive command-line utility, ipqosadmin, for managing
administrative tasks related to using HP-UX IPQoS. This utility can verify, load, and
unload a configuration; and show state, active configuration, and statistical information.
• Provides an API for (optional) programmatic HP-UX IPQoS control
Optionally, you can use the HP-UX IPQoS API to configure and manage HP-UX IPQoS.
For more information on the HP-UX IPQoS API, refer to the HP-UX IPQoS A.01.00
Programmer’s Guide.
• Provides statistics for configured adapters, policies, and filters
HP-UX IPQoS can display current statistics on all active adapters, policies, and filters. or
on specific adapters, policies, and filters, using the command-line utility, ipqosadmin.
You can also reset statistics using ipqosadmin.
• No changes to existing applications are required
No changes are needed to existing applications. You can immediately realize the benefits
of HP-UX IPQoS without any recoding, recompiling, or patching.
• Compatible with HP-UX IPSec
HP-UX IPQoS is compatible with HP-UX IPSec. HP-UX IPQoS can classify traffic by
transport port numbers when used with the IPSec Authentication Header (AH). However,
HP-UX IPQoS cannot classify traffic by transport port number when used with the IPSec
Encapsulating Security Payload (ESP), because the ESP protocol encrypts the IP payload.
HP-UX IPQoS can classify other filter attributes that are in the IP layer or below (such as
IP address), independent of HP-UX IPSec encryption mechanisms.
• IEEE802.3ad (Auto Port-aggregation) compatible
HP-UX IPQoS is IEEE802.3ad and IEEE802.3 compatible.
