why we can't create username

456 0 1 0

【Problem Description】

1. We are not able to create the user credential under AAA. We are getting Error message of "Wrong parameter found at ^ position".

2. We also noticed that it showing ~ before the hostname of SW which might have some alarm or significance.

【Problem Analysis】

1. As we checked, the username only has 4 characters, for our security rule, the name should be at least 6 characters.





Specifies the username.

The value is a character string in format user name+domain name delimiter+domain name. For example, in, @ is the domain name delimiter. The user name and domain name are case-insensitive, and cannot contain spaces and the following characters: / \ : * ? " < > | @ ' %. When security policy is enabled for local account, the value of user-name is a string of 6-253 characters; when security policy is disabled for local account, the value of user-name is a string of 1-253 characters. If no delimiter is specified, the system considers the entire character string as user name and the user belongs to the default domain.


After the security policy is disabled for local account, the * symbol can be used as a wildcard to match created user names and change passwords for the users in a batch.

2. When we disable security-enhance, the username can be configured as 1-253 characters.

<HUAWEI> system-view

[~HUAWEI] aaa

[~HUAWEI-aaa] undo local-user policy security-enhance

3. The character “~” means you are in configuration mode. The character “*” means you need to commit the configuration otherwise the new configuration will not take effect.

【Root Cause】

For security rule, the username should be at least 6 characters.

【Solution Description】

Run command “undo local-user policy security-enhance” to disable security-enhance, then the username can use 1-253 characters.
