Obtaining Technical Assistance
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.
Cisco Technical Support Website
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:
http://www.cisco.com/cisco/web/support/index.html
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:
https://tools.cisco.com/RPF/register/register.do
Submitting a Service Request
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:
https://tools.cisco.com/ServiceRequestTool/scm/mgmt/case
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
