operations running smoothly.

To ensure that all service requests are reported in a standard format, Cisco has established severity 
definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You 
and Cisco will commit all necessary resources around the clock to resolve the situation. 

Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your 
business operation are negatively affected by inadequate performance of Cisco products. You and Cisco 
will commit full-time resources during normal business hours to resolve the situation.

Severity 3 (S3)—Operational performance of your network is impaired, but most business operations 
remain functional. You and Cisco will commit resources during normal business hours to restore service 
to satisfactory levels.

Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or 
configuration. There is little or no effect on your business operations.

Information about Cisco products, technologies, and network solutions is available from various online 
and printed sources.
