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.
