Using the online TAC Case Open Tool is the fastest way to open P3 and P4 cases. (P3 and P4 cases are 
those in which your network is minimally impaired or for which you require product information.) After 
you describe your situation, the TAC Case Open Tool automatically recommends resources for an 
immediate solution. If your issue is not resolved using the recommended resources, your case will be 
assigned to a Cisco TAC engineer. The online TAC Case Open Tool is located at this URL:

For P1 or P2 cases (P1 and P2 cases are those in which your production network is down or severely 
degraded) or if you do not have Internet access, contact Cisco TAC by telephone. Cisco TAC engineers 
are assigned immediately to P1 and P2 cases to help keep your business operations running smoothly.

To open a case 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

To ensure that all cases are reported in a standard format, Cisco has established case priority definitions.

Priority 1 (P1)—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. 

Priority 2 (P2)—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.

Priority 3 (P3)—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.

Priority 4 (P4)—You require information or assistance with Cisco product capabilities, installation, or 
configuration. There is little or no effect on your business operations.

Information about Cisco products, technologies, and network solutions is available from various online
