How do I configure SNMP community name on S series switches

The snmp-agent community { read | write } community-name command can be used to configure community names on S series switches (except S1700). read indicates the read permission and write indicates the write permission. If the same community name is configured, the latter configuration overwrites the earlier community name.
The following provides an example:
[HUAWEI] snmp-agent community write community001

Community complexity check needs to be performed when SNMP community names are configured on S series switches (except S1700) in versions after V200R002. Community complexity requirements are as follows:
1. The community name must contain at least eight characters. The set password min-length command sets the value of minimum password length which must equal to or be larger than 8.
2. The community must be a combination of at least two of the following: uppercase letters A to Z, lowercase letters a to z, digits, and special characters (excluding question masks).

You can use the snmp-agent community complexity-check disable command to disable community name complexity check on a switch. After community name complexity check is disabled, the value of community name length is an integer in the range 1 to 32. The configuration method is as follows:
[HUAWEI] snmp-agent community complexity-check disable
Note: If a configured community name does not meet complexity requirements, the system is prone to attacks including password cracking from malicious users, affecting system security. Therefore, it is recommended that community name complexity check be enabled.
