While both the SAS and SASU programs are very similar, the primary difference is specific to the types of software updates that customers receive under each program.

The SAS service program provides your customers with:

• Access to Cisco online tools and resources, which includes application-specific white papers and best practices, design information, configuration information, troubleshooting tips, and alerts
• 24x7x365 access to technical assistance provided by technical specialists who are trained on Cisco software applications
