Intended Audience

This document is intended for:

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

Security Declaration

  • Encryption algorithm declaration

    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/RSA (RSA-2048 or higher)/SHA2/HMAC-SHA2 is recommended.

  • Password configuration declaration

    • Do not set both the start and end characters of a password to "%^%#". This causes the password to be displayed directly in the configuration file.

    • To further improve device security, periodically change the password.

  • Personal data declaration

    Your purchased products, services, or features may use users' some personal data during service operation or fault locating. You must define user privacy policies in compliance with local laws and take proper measures to fully protect personal data.

  • Feature declaration

    • The NetStream feature may be used to analyze the communication information of terminal customers for network traffic statistics and management purposes. Before enabling the NetStream feature, ensure that it is performed within the boundaries permitted by applicable laws and regulations. Effective measures must be taken to ensure that information is securely protected.
    • The mirroring feature may be used to analyze the communication information of terminal customers for a maintenance purpose. Before enabling the mirroring function, ensure that it is performed within the boundaries permitted by applicable laws and regulations. Effective measures must be taken to ensure that information is securely protected.
    • The packet header obtaining feature may be used to collect or store some communication information about specific customers for transmission fault and error detection purposes. Huawei cannot offer services to collect or store this information unilaterally. Before enabling the function, ensure that it is performed within the boundaries permitted by applicable laws and regulations. Effective measures must be taken to ensure that information is securely protected.
  • Reliability design declaration

    Network planning and site design must comply with reliability design principles and provide device- and solution-level protection. Device-level protection includes planning principles of dual-network and inter-board dual-link to avoid single point or single link of failure. Solution-level protection refers to a fast convergence mechanism, such as FRR and VRRP.

Special Declaration

  • This document serves only as a guide. The content is written based on device information gathered under lab conditions. The content provided by this document is intended to be taken as general guidance, and does not cover all scenarios. The content provided by this document may be different from the information on user device interfaces due to factors such as version upgrades and differences in device models, board restrictions, and configuration files. The actual user device information takes precedence over the content provided by this document. The preceding differences are beyond the scope of this document.

  • The maximum values provided in this document are obtained in specific lab environments (for example, only a certain type of board or protocol is configured on a tested device). The actually obtained maximum values may be different from the maximum values provided in this document due to factors such as differences in hardware configurations and carried services.

  • Interface numbers used in this document are examples. Use the existing interface numbers on devices for configuration.

  • The pictures of hardware in this document are for reference only.
