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/techsupport
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:

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 this URL:
http://www.cisco.com/techsupport/servicerequest
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
