When preparing to conduct a site survey for a Cisco® wireless LAN (WLAN) installation, follow the Cisco network design methodology: Prepare, Plan, Design, Implement, Operate, and Optimize (PPDIOO). PPDIOO addresses network implementation in phases. This paper will address the first four phases of this methodology. 

VMware vSphere™ introduces a number of new features and capabilities to virtual networking under VMware® vNetwork. vNetwork is the new name to describe the collection of networking technologies for optimally integrating networking and I/O functionality into vSphere. 

Presence can be defined as the indication, based on user-provided information, on whether co-workers are available and how they prefer to be reached. We will discuss an option that will allow our users to see availability status information of other users in the network via the Cisco Unified Presence Solution version 7.0. (CUPS). 

The way a switch learns Ethernet (MAC) addresses is by inspecting the Ethernet frame and recording the source MAC address in a dynamic table. The switch will also associate a learned MAC address with a port. It can then make intelligent forwarding decisions based on the destination MAC address. This white paper illustrates the process. 

In this white paper, we examine how to use Wireshark, the world's most popular open-source network analyzer, to troubleshoot some of the top causes of poor network performance, including high latency, packet loss, inefficient window sizes, intercepting devices, and application dependencies. 

This paper presumes that your enterprise already has a data network security policy in place. It examines the many different settings that are available to help secure the Cisco IP Phones from potential hacker attacks, and it looks at a selection of Cisco secure infrastructure technologies that are especially useful for protecting voice systems. 

This white paper addresses twelve common issues that network administrators should examine when troubleshooting network problems. 

In this paper examine 11 such myths and explore ways to use correct information about wireless LANs to make your networks scalable, secure and satisfying to your users. 

In this white paper, we will address the basics of this Layer 2 technology and help you get your network switch up and running. For our examples, we will use Cisco's 2950 switch. 

Build a basic foundation of knowledge about routers, the devices that allow you to move packets between networks, by reading this white paper. 

Troubleshooting is a necessary part of supporting any network installation. This paper will explain how to consider troubleshooting different problems that could exist in network.
