Technical Assistance Center
The Cisco Technical Assistance Center (TAC) is available to all customers who
need technical assistance with a Cisco product, technology, or solution. Two
levels of support are available: the Cisco TAC Web Site and the Cisco TAC
Escalation Center.
Cisco TAC inquiries 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.
•
Priority level 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.
The Cisco TAC resource that you choose is based on the priority of the problem
and the conditions of service contracts, when applicable.
Cisco TAC Web Site
You can use the Cisco TAC Web Site to resolve P3 and P4 issues yourself, saving
both cost and time. The site provides around-the-clock access to online tools,
knowledge bases, and software. To access the Cisco TAC Web Site, go to this
