Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity
definitions.
Severity 1 (S1)—An existing 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 operations 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 the network is impaired while 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.
