This chapter from Cisco Press supplies an overview of the technologies offered now to style networks. This site is very valuable in term of the beginner and advance lesson to get Cisco Certificates. CatOS devices ought to have PAgP set to off when connecting to a Cisco IOS application device if EtherChannels are not configured. Table 1-1 summarizes the many LAN technologies necessary to make effective campus networks. On top of that, if you use a modular chassis switch, such as the Cisco Catalyst 4500 or Catalyst 6500 family members of switches, these design and style considerations are not expected. The campus network topology is mainly LAN technologies connecting all the end systems inside the developing.
The enterprise edge contains all the network components for efficient and safe communication between the enterprise campus and remote locations, enterprise partners, mobile customers and the World-wide-web. In terms of campus technologies and protocols, I learned far much more from this book than I did from any of my research for Cisco’s expert-level certifications. A large campus with groups of buildings can also use WAN technologies to connect the buildings.
For these privileged to have Best Down Network Design, we know what I am speaking about: a self-contained book that delivers beyond a Cisco Certification test. New technologies such as 802.1x and VLAN assignment and Cisco Network Admission Control with quarantined VLAN, need to be used with transparent mode. Consequently, network designers commonly deploy a campus style optimized for the quickest functional architecture that runs on the existing physical wire.
The Cisco Catalyst 6500 and 4500 switches can support redundant supervisor engines and offer L2 Stateful Switchover (SSO), which ensures that the standby supervisor engine is synchronized from an L2 point of view and can speedily assume L2 forwarding responsibilities in the event of a supervisor failure. It contains the type of detail a single demands in study and in life with actual networks.
With the advent of such technologies as Layer three switching, LAN switching, and virtual LANs (VLANs), building campus networks is becoming far more complicated than in the past. Campus topologies with redundant network paths can converge more quickly than topologies that depend on redundant supervisors for convergence. All networks developed with ConceptDraw PRO are vector graphic documents and are out there for reviewing, modifying, and converting to a range of formats (image, HTML, PDF file, MS PowerPoint Presentation, Adobe Flash or MS Visio 2010, 2013).
