Intended Audience
This document is intended for:
l Data configuration engineers
l Commissioning engineers
l Network monitoring engineers
l System maintenance engineers
Security Declaration
l 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.

l 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.
l 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.
l 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.
l 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. If solution-level protection is used, ensure that the primary and backup paths
do not share links or transmission devices. Otherwise, solution-level protection may fail
to take effect.
Special Declaration
l 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.
l 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.
