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)—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.
