Technical Support Center

Cisco technical support is available to all customers who need technical assistance with a Cisco product, technology, or solution. Two types of support are available: the Cisco Technical Support Website and the Cisco 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 technical support 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 Technical Support Website

The Cisco Technical Support Website provides online documents and tools to help troubleshoot and resolve technical issues with Cisco products and technologies. To access the Cisco Technical Support Website, go to this URL:

http://www.cisco.com/techsupport

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

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 Technical Support Escalation Center

The Cisco Technical Support 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 Technical Support Escalation Center with a P1 or P2 problem, a Cisco technical support engineer automatically opens a case.
