About This Document

About This Document

Intended Audience

This document describes the concepts and configuration procedures of QoS features on the AR, and provides the configuration examples.

This document is intended for:

  • Data configuration engineers
  • Commissioning engineers
  • Network monitoring engineers
  • System maintenance engineers

Symbol Conventions

The symbols that may be found in this document are defined as follows.



Indicates a hazard with a high level of risk which, if not avoided, will result in death or serious injury.

Indicates a hazard with a medium level of risk which, if not avoided, could result in death or serious injury.

Indicates a hazard with a low level of risk which, if not avoided, could result in minor or moderate injury.

Indicates a potentially hazardous situation which, if not avoided, could result in equipment damage, data loss, performance deterioration, or unanticipated results.

NOTICE is used to address practices not related to personal injury.

Supplements the important information in the main text.

NOTE is used to address information not related to personal injury, equipment damage, and environment deterioration.

Command Conventions

The command conventions that may be found in this document are defined as follows.




The keywords of a command line are in boldface.


Command arguments are in italics.

[ ]

Items (keywords or arguments) in brackets [ ] are optional.

{ x | y | ... }

Optional items are grouped in braces and separated by vertical bars. One item is selected.

[ x | y | ... ]

Optional items are grouped in brackets and separated by vertical bars. One item is selected or no item is selected.

{ x | y | ... }*

Optional items are grouped in braces and separated by vertical bars. A minimum of one item or a maximum of all items can be selected.

[ x | y | ... ]*

Optional items are grouped in brackets and separated by vertical bars. Several items or no item can be selected.


The parameter before the & sign can be repeated 1 to n times.


A line starting with the # sign is comments.

Interface Numbering Conventions

Interface numbers used in this manual are examples. In device configuration, use the existing interface numbers on devices.

Security Conventions

  • Password setting
    • When configuring a password, the cipher text is recommended. To ensure device security, change the password periodically.
    • When you configure a password in plain text that starts and ends with %@%@, @%@%, %#%#, or %^%# (the password can be decrypted by the device), the password is displayed in the same manner as the configured one in the configuration file. Do not use this setting.
    • When you configure a password in cipher text, different features cannot use the same cipher-text password. For example, the cipher-text password set for the AAA feature cannot be used for other features.
  • Encryption algorithm

    Currently, the device uses the following encryption algorithms: 3DES, AES, RSA, SHA1, SHA2, and MD5. 3DES, RSA and AES are reversible, while SHA1, SHA2, and MD5 are irreversible. The encryption algorithms DES, 3DES, RSA (RSA-1024 or lower), MD5 (in digital signature scenarios and password encryption), and SHA1 (in digital signature scenarios) have a low security, which may bring security risks. If protocols allowed, using more secure encryption algorithms, such as AES, RSA (RSA-2048 or higher), SHA2, and HMAC-SHA2, is recommended. The encryption algorithm depends on actual networking. The irreversible encryption algorithm must be used for the administrator password, SHA2 is recommended.

  • Personal data

    Some personal data (such as MAC or IP addresses of terminals) may be obtained or used during operation or fault location of your purchased products, services, features, so you have an obligation to make privacy policies and take measures according to the applicable law of the country to protect personal data.

  • The terms mirrored port, port mirroring, traffic mirroring, and mirroring in this manual are mentioned only to describe the product's function of communication error or failure detection, and do not involve collection or processing of any personal information or communication data of users.


  • This manual is only a reference for you to configure your devices. The contents in the manual, such as web pages, command line syntax, and command outputs, are based on the device conditions in the lab. The manual provides instructions for general scenarios, but do not cover all usage scenarios of all product models. The contents in the manual may be different from your actual device situations due to the differences in software versions, models, and configuration files. The manual will not list every possible difference. You should configure your devices according to actual situations.
  • The specifications provided in this manual are tested in lab environment (for example, the tested device has been installed with a certain type of boards or only one protocol is run on the device). Results may differ from the listed specifications when you attempt to obtain the maximum values with multiple functions enabled on the device.
  • In this document, public IP addresses may be used in feature introduction and configuration examples and are for reference only unless otherwise specified.
  • In this document, NetEngine access routers include AR600&AR1600&AR6000&AR6000-S Series.
