Overview of this book

Most enterprises use Cisco networking equipment to design and implement their networks. However, some networks outperform networks in other enterprises in terms of performance and meeting new business demands, because they were designed with a visionary approach. The book starts by describing the various stages in the network lifecycle and covers the plan, build, and operate phases. It covers topics that will help network engineers capture requirements, choose the right technology, design and implement the network, and finally manage and operate the network. It divides the overall network into its constituents depending upon functionality, and describe the technologies used and the design considerations for each functional area. The areas covered include the campus wired network, wireless access network, WAN choices, datacenter technologies, and security technologies. It also discusses the need to identify business-critical applications on the network, and how to prioritize these applications by deploying QoS on the network. Each topic provides the technology choices, and the scenario, involved in choosing each technology, and provides configuration guidelines for configuring and implementing solutions in enterprise networks.

A sample network

Finally, let's consider the sample network for the sample organization discussed earlier. The design assumptions are as follows:

  • There are two floors in the campus. Each floor has an area for development users and nondevelopment users. Development and nondevelopment users have to be separated from each other.
  • Each floor has 80-100 development users that can go up to 120 on each floor.
  • Each floor has 30 nondevelopment users that can go up to 50 on each floor.

The campus design for this will look similar to the following figure:

Figure 68: Connecting multiple switches in a stack

Some of the important observations about the design are as follows:

  • Stack 1 caters to the users on floor 1 and stack 2 caters to users on floor 2.
  • Stack A has some ports configured in VLAN 10 for development users and VLAN 20 for nondevelopment users.
  • Stack B has some ports configured...
