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.

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.
