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.
