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:
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:
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:
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC website so that you can
describe the situation in your own words and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. These classifications are assigned when
severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1
or P2 problem, a Cisco TAC engineer automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this URL:
Before calling, please check with your network operations
center to determine the level of Cisco support services to which your
company is entitled: for example, SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). When you call the
center, please have available your service agreement number and your product serial number.
