The Cisco TAC is available to all customers who ne ed te ch ni cal as si s ta nc e w it h a C isc o product,
technology, or solution. Two types of support are available through the Cisco TAC: the Cisco TAC
WebSit e a nd th e 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. Ne twork functionality is noticea bly
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.
Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of
service contracts, when applic ab le.
