About This Document
Intended Audience
This document describes the parameters, meaning, possible causes, and solution of logs.
This document provides a complete set of logs, which helps intended readers check the running status of the device, analyze the network status, and locate the problem cause, so as to provide a reference for system diagnosis and maintenance.
This document is intended for:
- Commissioning engineers
- Network monitoring engineers
- System maintenance engineers

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 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.
Reference Standards and Protocols
To obtain reference standards and protocols, log in to Huawei official website, search for "protocol compliance list", and download the Huawei AR Series Standard and Protocol Comply Table.
Declaration
- 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, AR series IOT gateway include AR500&AR510&AR531&AR550&AR1500&AR2500 Series.
