The Knowledge Base contains a wealth of information on topics related to Cisco products. 

Articles generally fall into one of the following categories:

How-To. These articles explain how to do something with a Cisco product. For example, a how-to 
article might explain the procedures for backing up and restoring a database for an appliance.

Problem-and-Solution. A problem-and-solution article addresses a particular error or issue that 
you might encounter when using a Cisco product. For example, a problem-and-solution article might 
explain what to do if a specific error message is displayed when you upgrade to a new version of the 
product.

Reference. Reference articles typically provide lists of information, such as the error codes 
associated with a particular piece of hardware.

Troubleshooting. Troubleshooting articles explain how to analyze and resolve common issues 
related to Cisco products. For example, a troubleshooting article might provide steps to follow if you 
are having problems with DNS.

Each article in the Knowledge Base has a unique answer ID number. 

The Cisco Support Community is an online forum for Cisco customers, partners, and employees. It 
provides a place to discuss general email and web security issues, as well as technical information about 
specific Cisco products. You can post topics to the forum to ask questions and share information with 
other Cisco users.
