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.
Cisco TAC Website
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 software. To access the Cisco TAC website, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have
complete access to the technical support resources on the Cisco TAC website.
Some services on the Cisco TAC website require 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 this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical
issues by using the Cisco TAC website, you can open a case online at this URL:
