Example: Configuring local authentication, HWTACACS authorization, and RADIUS accounting for SSH users

As shown in Figure 12, configure the switch to meet the following requirements:

• Perform local authentication for SSH users.

• Use the HWTACACS server and RADIUS server for SSH user authorization and accounting, respectively.

• Exclude domain names from the usernames sent to the servers.

• Assign the default user role network-operator to SSH users after they pass authentication.

Configure an account named hello for the SSH user. Configure the shared keys to expert for secure communication with the HWTACACS server and RADIUS server.

# Set the shared keys to expert for secure communication with the switch, add an account for the SSH user, and specify the password. (Details not shown.)

# Set the shared keys to expert for secure communication with the switch, add an account for the SSH user, and specify the password. (Details not shown.)

# Configure IP addresses for interfaces. (Details not shown.)

# Create local RSA and DSA key pairs.

# Enable the SSH service.

# Enable scheme authentication for user lines VTY 0 through VTY 63.

# Set the password to 123456TESTplat&! in plaintext form for the local user. In FIPS mode, you must set the password in interactive mode.

# Create an ISP domain named bbb and configure the login users to use local authentication, HWTACACS authorization, and RADIUS accounting.

[Switch] domain bbb

# Enable the default user role feature to assign authenticated SSH users the default user role network-operator.

[Switch] role default-role enable

# Initiate an SSH connection to the switch, and enter username hello@bbb and the correct password. The user logs in to the switch. (Details not shown.)

# Verify that the user can use the commands permitted by the network-operator user role. (Details not shown.)
