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 provides online documents and tools
for troubleshooting and resolving technical issues with Cisco products and technologies. The website remains available 24
hours a day, 365 days a year at this URL: http://www.cisco.com/techsupport
Using the online TAC Service Request Tool represents the fastest way to open S3 and S4 service requests. (S3 and S4 service
requests specify those requests 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 by using the recommended resources, your service request will get assigned to a Cisco TAC engineer. Find the
TAC Service Request Tool 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 represent those in which your production network is down or severely degraded.) Cisco TAC engineers get 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
