Cisco TAC Website
You can use the Cisco TAC website to resolve P3 and P4 issues yourself, saving both cost and time. The
site provides around-the-clock access to online tools, knowledge bases, and software. To access the
Cisco TAC website, go to this URL:
http://www.cisco.com/tac
All customers, partners, and resellers who have a valid Cisco service contract have complete access to
the technical support resources on the Cisco TAC website. Some services on the Cisco TAC website
require a Cisco.com login ID and password. If you have a valid service contract but do not have a login
ID or password, go to this URL to register:
http://tools.cisco.com/RPF/register/register.do
If you are a Cisco.com registered user, and you cannot resolve your technical issues by using the Cisco
TAC website, you can open a case online at this URL:
http://www.cisco.com/en/US/support/index.html
If you have Internet access, we recommend that you open P3 and P4 cases through the Cisco TAC
website so that you can describe the situation in your own words and attach any necessary files.
Cisco TAC Escalation Center
The Cisco TAC Escalation Center addresses priority level 1 or priority level 2 issues. 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
automatically opens a case.
To obtain a directory of toll-free Cisco TAC telephone numbers for your country, go to this 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). When you call the center, please have available your service agreement
number and your product serial number.
