Cisco Networking All-in-One For Dummies, 2nd Edition

Cisco networks bring together a lot of moving parts: addressing, switching, routing, wireless access, and security all have to work in concert. In Cisco Networking All-in-One For Dummies, 2nd Edition, Edward Tetz arranges those subjects into six clearly named sections, giving readers a practical map from networking fundamentals to Cisco-focused configuration and management topics.

Six books, one networking reference

The book opens with network design and core concepts, including the OSI model, troubleshooting by layer, packets, and the Cisco Internetwork Operating System. From there, it progresses through Internet protocols, switching, routing, wireless, and security and management. That sequence makes it useful both for reading through a subject area and for returning to a particular topic when a question comes up.

From IP fundamentals to switching and routing

Coverage of IPv4 and IPv6, TCP and UDP, ARP, and data-link troubleshooting builds a foundation for the chapters on configuring switches and routers. The switching section includes VLANs, VTP, STP, EtherChannel, and device discovery with CDP. Routing topics range from static routes and WAN links to RIP, EIGRP, OSPF, IS-IS, BGP, and IP multicast.

Wireless, security, and network management

Later sections turn to planning and securing wireless LANs, building a Cisco wireless network, and protecting infrastructure with security tools, access control lists, NAT, and Cisco’s Adaptive Security Appliance. The contents also include security best practices and a chapter on AI, management tools, and automation.

A useful perspective for Cisco learners

Students, network administrators, and practitioners working with Cisco technologies can use this second edition to revisit fundamentals or look across the major disciplines involved in operating a network. Its broad, organized scope helps connect individual configurations and protocols to the larger design and management picture.
