Understand the tools, commands, and methodologies that enable reliable performance for remote access services in an enterprise environment. Expert advice on supporting remote access networks with detailed descriptions of Cisco troubleshooting tools. Structured troubleshooting methodologies for enterprise remote access technologies, including Dial, ISDN, Frame Relay, and VPNs.* Examination of network symptoms, show commands, line-by-line explanations of debug output, and overviews of remote access management.Troubleshooting Remote Access Enterprise Networks helps you understand underlying technologies and gain insight into the challenges, issues, and best practices for supporting remote access networks. Covering fundamental concepts, design issues, provisioning, DSL and Cable connectivity options, central office operations, authentication techniques, and troubleshooting, this book serves as a comprehensive tool to resolving remote access issues. In-depth analysis of essential remote access technologies provides greater insight into Dial, ISDN, Frame Relay, and VPNs. With a focus specifically on the more popular enterprise applications of these technologies, each major section discusses troubleshooting methodology and scenarios. The methodology walks readers through the process of identifying, isolating, and correcting common failures. This structured approach helps limit the inclination to attack network failures in a more random fashion, which is not nearly as efficient. Explanations of typical symptoms, problems, show commands, and debug information are also extensive.Plamen Nedeltchev is a Technical SolutionsConsultant in the Remote Access Services group at Cisco Systems.
