The Cisco TAC website (

) provides online documents and tools for 

troubleshooting and resolving technical issues with Cisco products and technologies. The Cisco TAC 
website is available 24 hours a day, 365 days a year.

Accessing all the tools on the Cisco TAC website requires a Cisco.com user ID and password. If you 
have a valid service contract but do not have a login ID or password, register at this URL:

The online TAC Case Open Tool (

) is the fastest way to open P3 and 

P4 cases. (Your network is minimally impaired or 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 these recommendations, your case will be assigned to a Cisco TAC 
engineer.

For P1 or P2 cases (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 
USA: 1 800 553-2447

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.
