snmp-agent usm-user password complexity-check disable

Usage Scenario

After the complexity check is enabled for SNMPMv3 user passwords, a newly-configured SNMPv3 user password needs to meet the requirements for the complexity check. After complexity check is disabled for SNMPv3 user passwords, the complexity of the passwords is not checked.

The requirements for the complexity of SNMPv3 user passwords are as follows:

• The minimum password length is configured by using the set password min-length command. By default, a password contains 8 characters.

• A password includes at least two kinds of characters: uppercase letters, lowercase letters, numbers, and special characters (excluding question marks (?) and spaces).

Precautions

• When complexity check is disabled for SNMPv3 user passwords, complexity of a newly-configured SNMPv3 user password is not checked. If a configured SNMPv3 user password is simple and does not meet the complexity requirements, the password may be easily attacked and cracked down by unauthorized users, affecting device security. Therefore, enabling the complexity check for SNMPv3 user passwords is recommended.
• In the configuration restoration stage, complexity check is not performed for SNMPv3 user passwords.
• Enabling the complexity check for SNMPv3 user passwords does not affect the SNMPv3 user passwords that have been configured.
