I have purchased two cisco ips moudles and smartnet service.
How to create CCO account to download software and update signatures for ASA-AIP-SSM-20?
Create a standard Cisco account then click "Account" on top right of cisco page, click profile manager to update your company details.
Then under ACCESS RESTRICTED CONTETS enter your Service Contract Number that you received from cisco.
It can take 1-2 days before you can see that contract under View Current Contracts
Hope that helps.
