Preface
Obtaining Technical Assistance
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.
•
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 applicable.
Cisco TAC Web Site
The Cisco TAC Web Site allows you 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 the
following URL:
All customers, partners, and resellers who have a valid Cisco services contract
have complete access to the technical support resources on the Cisco TAC Web
Site. The Cisco TAC Web Site
requires a Cisco.com login ID and password. If you
have a valid service contract but do not have a login ID or password, go to the
following URL to register:
http://www.cisco.com/register/
If you cannot resolve your technical issues by using the Cisco TAC Web Site, and
you are a Cisco.com registered user, you can open a case online by using the TAC
Case Open tool at the following URL:
http://www.cisco.com/tac/caseopen
If you have Internet access, it is recommended that you open P3 and P4 cases
through the Cisco TAC Web Site.
