Technical Assistance Center
The Cisco TAC is available to all customers who need technical assistance with a Cisco product,
technology, or solution. Two types of support are available: the Cisco TAC website and the Cisco TAC
Escalation Center. The type of support that you choose depends on the priority of the problem and the
conditions stated in service contracts, when applicable.
We categorize Cisco TAC inquiries according to urgency:
• Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration. There is little or no impact to your business
operations.
• Priority level 3 (P3)—Operational performance of the network is impaired, but most business
operations remain functional. You and Cisco are willing to commit resources during normal
business hours to restore service to satisfactory levels.
• Priority level 2 (P2)—Operation of an existing network is severely degraded, or significant aspects
of your business operations are negatively impacted by inadequate performance of Cisco products.
You and Cisco will commit full-time resources during normal business hours to resolve the
situation.
• Priority level 1 (P1)—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.
