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
WebSite 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.
