For all customers, partners, resellers, and distributors who hold valid Cisco service contracts, Cisco 
Technical Support provides 24-hour-a-day, award-winning technical assistance. The Cisco Technical 
Support Website on Cisco.com features extensive online support resources. In addition, Cisco Technical 
Assistance Center (TAC) engineers provide telephone support. If you do not hold a valid Cisco service 
contract, contact your reseller.

The Cisco Technical Support Website provides online documents and tools for troubleshooting and 
resolving technical issues with Cisco products and technologies. The website is available 24 hours a day, 
365 days a year at this URL:

Access to all tools on the Cisco Technical Support Website requires a Cisco.com user ID and password. 
If you have a valid service contract but do not have a user ID or password, you can register at this URL:

Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 
and S4 service requests are those in which your network is minimally impaired or for which you require 
product information.) After you describe your situation, the TAC Service Request Tool automatically 
provides recommended solutions. If your issue is not resolved using the recommended resources, your 
service request will be assigned to a Cisco TAC engineer. The TAC Service Request Tool is located at 
this URL:

For S1 or S2 service requests or if you do not have Internet access, contact the Cisco TAC by telephone. 
(S1 or S2 service requests are those in which your production network is down or severely degraded.) 
Cisco TAC engineers are assigned immediately to S1 and S2 service requests to help keep your business 
operations running smoothly.

To open a service request by telephone, use one of the following numbers:

Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553 2447

To ensure that all service requests are reported in a standard format, Cisco has established severity 
definitions.

Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You 
and Cisco will commit all necessary resources around the clock to resolve the situation.
