3Configure RADIUS server

[Router] radius server 129.7.66.66 authentication-port 1000

accounting-port 1001

[Router] radius server 129.7.66.67

4Configure RADIUS server shared secret, retransmission times, and time length of timeout timer

[Router] radius shared-key this-is-my-secret

[Router] radius retry 2

5Configure real-time accounting with interval of 5 minutes

[Router] radius timer realtime-accounting 5

Authenticating an FTP

The authentication server is 129.7.66.66, numbers of ports being 1812 and 1813.

User

Authenticate and charge FTP users using RADIUS server first, and if there is no

 

 

response, do not authenticate or charge them.

 

See Figure 169.

1

Enable AAA and configure default authentication method list of FTP user.

 

[Router]aaa-enable

 

[Router]aaa authentication-scheme login default radius none

2

Enable FTP server

 

[Router]ftp-server enable

3

Configure user abc and authorize the user to use FTP service.

 

[Router] local-user abc service-type ftp password simple hello

4

Configure RADIUS server IP address and port, using default port number

 

[Router]radius server 129.7.66.66

5

Configure RADIUS server shared secret, retransmission times, timeout and RADIUS

 

server dead time.

 

[Router] rad shared-key this-is-my-secret

 

[Router] radius retry 4

 

[Router] radius timer response-timeout 2

 

[Router] radius timer quiet 1

 

 

Troubleshooting AAA

Local user authentication is always rejected

and RADIUS

Follow the steps below.

 

1

Check whether correct password has been configured in local-usercommand.

2

Check whether the authorized service-type is correct.

3

accounting-scheme optional is not configured, check whether the RADIUS

 

server can be pinged through. Also check whether the address, port number and

 

key of RADIUS server configured on the router for accounting are identical with

 

those on the RADIUS server in use.

4

If the operation above does not work, use the radius server command to
