About This Document

Purpose

The documents describe the configuration of various services supported by the CX320 switch module. The description covers configuration examples and function configurations.

Intended Audience

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.

Command Conventions

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

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.

  • Do not start and end a cipher-text password with %^%#. By default, the system considers the password starting and ending with %^%# as valid cipher-text password that can be decrypted. The password displayed in the configuration file is the same as the cipher-text password entered by the user. After the system root key is set using the set master-key command, do not start and end the key with %@%# because the string starting and ending with %@%# is considered as a valid cipher-text key.

  • 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)/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 (AES-128 or higher), RSA (RSA-2048 or higher), SHA2 (SHA2-256 or higher), and HMAC-SHA2 (HMAC-SHA2-256 or higher), 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 Remote access

  • The Telnet protocol is not secure. Data is not encrypted during transmission over Telnet. Therefore, transmitted data may be restored after IP packets are captured without authorization. It is recommended that files be transmitted over SSH.

  • The FTP and TFTP protocol is not secure. Data is not encrypted during transmission over FTP and TFTP. Therefore, transmitted data may be restored after IP packets are captured without authorization. It is recommended that files be transmitted over SFTP.

  take measures according to the applicable law of the country to protect personal data.

• The terms mirrored port, port mirroring, traffic mirroring, and mirroing 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.

• Budong setting

  To ensure secure service application, periodically upgrade the switch module software version.

Declaration

This manual is only a reference for you to configure your devices. The contents in the manual, such as 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.
