TAC Case Priority Definitions

To ensure that all cases are reported in a standard format, Cisco has established
case priority definitions.
Priority 1 (P1)—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.
Priority 2 (P2)—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.
Priority 3 (P3)—Operational performance of your network is im pa ired, but most
business operations remain functional. You and Cisco will commit resources
during normal business hours to restore service to satisfactory levels.
Priority 4 (P4)—You require information or assistance with Cisco product
capabilities, installation, or configuration. There is little or no effect on your
business operations.
