Cisco Systems 11000 Series Manual De Usuario

We categorize Cisco TAC inquiries according to urgency:

Priority level 4 (P4)—You need information or assistance concerning Cisco 
product capabilities, product installation, or basic product configuration. 
There is little or no impact to your business operations.

Priority level 3 (P3)—Operational performance of the network is impaired, 
but most business operations remain functional. You and Cisco are willing to 
commit resources during normal business hours to restore service to 
satisfactory levels.

Priority level 2 (P2)—Operation of an existing network is severely degraded, 
or significant aspects of your business operations are negatively impacted by 
inadequate performance of Cisco products. You and Cisco will commit 
full-time resources during normal business hours to resolve the situation.

Priority level 1 (P1)—An existing 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.

The Cisco TAC website provides online documents and tools to help troubleshoot 
and resolve technical issues with Cisco products and technologies. To access the 
Cisco TAC website, go to this URL:

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

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:

If you have Internet access, we recommend that you open P3 and P4 cases online 
so that you can fully describe the situation and attach any necessary files.
