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.
Cisco TAC Website
The Cisco TAC website provides online documents and tools to help troubleshoot and resolve technical
issues with Cisco products and technologies. To access the Cisco TAC website, go to this URL:
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
require a Cisco.com login ID and password. If you have a valid service contract but do not have a login
ID or password, go to this URL to register:
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC website, you can open a case online at this URL:
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.

Before calling, please check with your network operations center to determine the Cisco support services
