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.

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website

http://www.cisco.com/tac/caseopen

Obtaining Additional Publications and Information

• 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.

If you have Internet access, we recommend that you open P3 and P4 cases online so that you can fully
describe the situation and attach any necessary files.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These
classifications are assigned when severe network degradation significantly impacts business operations.
When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer
automatically opens a case.
