STEP  3 Generate CSR a that contains fields that identify your organization, and location. 
For example:
openssl req -new -key <file.key> -out <file.csr>
You must have the following information:
• Subject field—Enter the Common Name (CN) that must be a FQDN (Fully 
Qualified Domain Name) syntax. During SSL authentication handshake, the 
SPA 9000 verifies that the certificate it receives is from the machine that 
presented it.
• Server's hostname—For example, provserv.domain.com.
• Email address—Enter an email address so that customer support can 
contact you if needed. This email address is visible in the CSR. 
STEP  4 Email the CSR (in zip file format) to the Cisco support person or to 
linksys-
icertadmin@cisco.com
. The certificate is signed by Cisco and given to you.
