Technical Assistance Center

The Cisco 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. The avenue 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.

• 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.

You can use the Cisco TAC website 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
