If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC
Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority
level 2; these classifications are assigned when severe network degradation significantly impacts
business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC
engineer will automatically open a case.

To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to the following

services to which your company is entitled; for example, SMARTnet, SMARTnet Onsite, or Network
