Obtaining Technical Assistance  
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:  
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:  
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.

Definitions of Service Request Severity  
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.  
Severity 2 (S2)—Operation of an existing network is severely degraded, or  
significant aspects of your business operation are negatively affected by  
inadequate performance of Cisco products. You and Cisco will commit full-time  
resources during normal business hours to resolve the situation.  
Severity 3 (S3)—Operational performance of your network is impaired, but most  
business operations remain functional. You and Cisco will commit resources  
during normal business hours to restore service to satisfactory levels.  
Severity 4 (S4)—You require information or assistance with Cisco product  
capabilities, installation, or configuration. There is little or no effect on your  
business operations.
