Preface 

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 
provides recommended solutions. If your issue is not resolved using the recommended resources, 
your service request is 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. 

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.
