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 in plain text, the password is saved in the configuration file in plain text. The plain text has high security risks. The cipher text is recommended. To ensure device security, change the password periodically.
- When you configure a password in cipher text that starts and ends with %@%@ (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.
- Encryption algorithm
Currently, the device uses the following encryption algorithms: DES, AES, SHA-1, SHA-2, and MD5. DES and AES are reversible, and SHA-1, SHA-2, and MD5 are irreversible. The encryption algorithm depends on actual networking. If protocols are used for interconnection, the locally stored password must be reversible. It is recommended that the irreversible encryption algorithm be used for the administrator password.
- 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.
