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 through the Cisco TAC: the Cisco TAC
WebSite and the Cisco TAC Escalation Center.
Inquiries to Cisco TAC are categorized according to the urgency of the issue:
•Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities,
product installation, or basic product configuration.
•Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably
impaired, but most business operations continue.
•Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects
of business operations. No workaround is available.
•Prioritylevel 1 (P1)—Your production network is down,and a critical impact to business operations
will occur if service is not restored quickly. No workaround is available.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of
service contracts, when applicable.
