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 URL:
http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Before calling, please check with your network operations center to determine the
level of Cisco support services to which your company is entitled; for example,
SMARTnet, SMARTnet Onsite, or Network Supported Accounts (NSA). In
addition, please have available your service agreement number and your product
serial number.
