Examples for Configuring Local Authentication and Authorization

The configuration examples refer to the applications of local authentication and authorization on the actual network.

Networking Requirements

As shown in Figure 1, the administrator admin@aaa logs in to the router through Telnet and uses local authentication and authorization. The admin@aaa user can execute all AAA command lines. The user, however, can only view ACL command lines and cannot configure ACL command lines.

Precautions

None

Configuration Roadmap

Configure local user authentication and authorization as follows:

Configure the task group and add tasks of the corresponding module.
Configure the user group, bind the corresponding task group, and bind the user group to a domain.
Configure the user and specify the user group of the user.
Configure the user authentication and authorization modes.

Data Preparation

To complete the configuration, you need the following data:

Task group name
User group name
Domain name

Procedure

Configure the task group.

# Create a task group.

<HUAWEI> system-view
[~HUAWEI] aaa
[~HUAWEI-aaa] task-group admin

# Add AAA read-write tasks and ACL read-only tasks to the task group.

[*HUAWEI-aaa-task-group-admin] task aaa execute write read
[*HUAWEI-aaa-task-group-admin] task acl read
[*HUAWEI-aaa-task-group-admin] task config read write execute debug
[*HUAWEI-aaa-task-group-admin] commit
[~HUAWEI-aaa-task-group-admin] quit

Create a user group and bind the task group to the user group, and then bind the user group to the domain.
Create a user group.
```
[~HUAWEI-aaa] user-group admin
```
# Bind the task group to the user group.
```
[*HUAWEI-aaa-user-group-admin] task-group admin
[*HUAWEI-aaa-user-group-admin] commit
[~HUAWEI-aaa-user-group-admin] quit
```

Configure the user authentication and authorization schemes.

# Configure a local authentication scheme.

[~HUAWEI-aaa] authentication-scheme localtype
[*HUAWEI-aaa-authen-localtype] authentication-mode local
[*HUAWEI-aaa-authen-localtype] commit
[~HUAWEI-aaa-authen-localtype] quit

# Configure a local authorization scheme.

[~HUAWEI-aaa] authorization-scheme localtype
[*HUAWEI-aaa-author-localtype] authorization-mode local
[*HUAWEI-aaa-author-localtype] commit
[~HUAWEI-aaa-author-localtype] quit

# Reference the authentication and authorization schemes under the domain.

[~HUAWEI-aaa] domain aaa
[*HUAWEI-aaa-domain-aaa] authentication-scheme localtype
[*HUAWEI-aaa-domain-aaa] authorization-scheme localtype
[*HUAWEI-aaa-domain-aaa] commit
[~HUAWEI-aaa-domain-aaa] quit

Create a local user.

[~HUAWEI-aaa] local-user admin@aaa password cipher Huawei-123
[*HUAWEI-aaa] local-user admin@aaa user-group admin
[*HUAWEI-aaa] commit
[~HUAWEI-aaa] quit
[~HUAWEI] telnet server enable
[*HUAWEI] commit

Verify the configuration.
After the preceding configurations are complete, log in to the network through the Telnet. In this case, you can only execute AAA commands and view ACL commands, but you cannot configure the commands.
```
[~HUAWEI] acl 3000
Error: No permission to run the command.
```
