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 email (public) or gives access to them on a remote host (private). Typically,
the CA provides the certificate files listed in Table 22 .
4. On each switch:
a. Install the certificate.
b. 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 certificate authority
To ease maintenance and allow secure out-of-band communication between switches, consider using one
certificate authority (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 might accept a 2048-bit key. Consider your fabric configuration, check CA
Web sites 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:
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:
Because CA support for the 2048-bit key size is limited, you should select 1024 in most cases.
