Summary of SSL procedures You configure for SSL by obtaining, installing, and activating digital certificates for SSL support. Certificates are required on all switches that are to be accessed through SSL. You also need to install a certificate in the Java Plug-in on the management workstation, and you may need to add a certificate to your Web browser. Configuring for SSL involves these major steps, which are shown in detail in the next sections. 1. Choose a Certificate Authority (CA). 2. Generate the following items on each switch: a. A public/private key (secCertUtil genkey command). b. A certificate signing request (CSR) (secCertUtil gencsr command) and store the CSR on an FTP server (secCertUtil export command). 3. Obtain the certificates from the CA. You can request a certificate from a CA through a Web browser. After you request a certificate, the CA either sends certificate files by e-mail (public) or gives access to them on a remote host (private). Typically, the CA provides the certificate files listed in Table 20. Table 20 SSL certificate files Certificate file Description name.crt nameRoot.crt The switch certificate. The root certificate. Typically, this certificate is already installed in the browser, but if not, you must install it. nameCA.crt The CA certificate. It needs to be installed in the browser to verify the validity of the server certificate or server validation fails. 4. On each switch, install and then activate the certificate. 5. If necessary, install the root certificate to the browser on the management workstation. 6. Add the root certificate to the Java Plug-in keystore on the management workstation. Choosing a CA To ease maintenance and allow secure out-of-band communication between switches, consider using one CA to sign all management certificates for a fabric. If you use different CAs, management services operate correctly, but the Web Tools Fabric Events button is unable to retrieve events for the entire fabric. Each CA (for example, Verisign or GeoTrust) has slightly different requirements; for example, some generate certificates based on IP address, while others require an FQDN, and most require a 1024-bit public/private key while some may accept a 2048-bit key. Consider your fabric configuration, check CA websites for requirements, and gather all the information that the CA requires. Generating a public/private key Perform this procedure on each switch. 1. Connect to the switch and log in as admin. 2. Enter this command to generate a public/private key pair: switch:admin> seccertutil genkey The system reports that this process will disable secure protocols, delete any existing CSR, and delete any existing certificates. 3. Respond to the prompts to continue and select the key size: Continue (yes, y, no, n): [no] y Select key size [1024 or 2048]: 1024 Generating new rsa public/private key pair Done. 90 Configuring standard security features
