Changing the Password of the Account for Reporting Alarms (SNMP v3)

Prerequisites

• The username and password for logging in to the console have been obtained.
• The username and password for logging in to a server have been obtained.

Context

This section introduces the procedures in Windows and Linux.

There may be security risks if you use the same password for SNMP v3 authentication and data encryption. To ensure system security, you are advised to set different passwords for SNMP v3 authentication and data encryption.

Obtain the initial authentication password from technical support.

The password must meet the following complexity requirements:

• Contains 8 to 16 characters.
• Contains at least one of the following special characters: `~!@#$%^&*()-_=+\|[{}];:'",<.>/?
• Contains at least two of the following types of characters:
  • Uppercase letters
  • Lowercase letters
  • Numeric characters
• Cannot be the same as the username or the username in reverse order.
• Cannot be the same as the old passwords.
• Cannot contain spaces.
