Configuring Mutual Authentication for RADIUS

Install or import the certificates.

At least one RADIUS server must be configured on the device using the radius-server host command.

To configure Mutual Authentication do the following:

Import the RADIUS client certificate. Use the following command.

crypto ca import-pkcs type pkcs12 cert-type radius-client protocol FTP directory /mydir-name file /myfile-name source-ip 10.9.9.2 user user-name password password

Import the RADIUS server CA certificates.

crypto import radiusca directory /mydir-name file /myfile-name host 10.11.12.13 user user-name password password

Configure the RADIUS server and AAA authentication. Navigate to the global configuration mode. This configures a RADIUS server with IP 10.11.12.13 with port 2083.
```
SLX (config)# radius-server host 10.11.12.13 use-vrf mgmt-vrf
SLX (config)# auth-port 2083.  
```
Enable RADIUS security.
```
SLX (config)# radsec 
```

Configure AAA globally.

SLX(config)# aaa authentication login radius local-auth-fallback
