CCNA Exploration 4.0 Chapter 10 - Planning and Cabling Networks Học viện mạng Bách khoa - Website: www.bkacad.com Overview • Identify the basic network media required to make a LAN connection. • Identify the types of connections for intermediate and end device connections in a LAN. – Identify the pin out configurations for straight-through and crossover cables. Học viện mạng Bách khoa - Website: www.bkacad.com - Identify the different cabling types, standards and ports used for WAN connections. - Define the role of device management connections when using Cisco equipment. • Design an addressing scheme for an inter-network and assign ranges for hosts, network devices and the router interface. • Compare and contrast the importance of network designs LANs – Making the Physical Connections Học viện mạng Bách khoa - Website: www.bkacad.com Connections Basic Network Media Required to Make a LAN Connection • Select the appropriate hardware, including the cabling, to install several computers together in a LAN Học viện mạng Bách khoa - Website: www.bkacad.com Router: • interconnect two LAN • interconnect a LAN and a WAN Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com Hubs: for small LAN Switches: for LAN • Number of factors that need to be considered Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com Cost • The cost of a switch is determined by: capacity (port available and switching speed), features, network management capabilities, security technologies, and optional advanced switching technologies. • "cost per port" calculation, cable length. • The invest in redundancy. The effect if there are problems with a single central switch. Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com Speed and Types of Ports/Interfaces • The speed : 10/100/1000 Mbps. Can increased speeds without replacing the devices. • The number and type of ports: – Just enough ports for today's needs? – A mixture of UTP speeds? – Both UTP and fiber ports? • The number of UTP ports and fiber ports will be needed. The number of 1 Gbps ports and 10/100 Mbps ports. Factors to Consider in Choosing a Router • Similar to the switch, cost and interface types and speeds must be considered as well. Additional factors: – Expandability – Media – Operating System Features Expandability Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com Expandability • Fixed configurations • Modular devices • Most modular devices come with a basic number of fixed ports as well as expansion slots. • Select the appropriate modules and interfaces for the specific media. Operating System Features • features and services such as: – Security – Quality of Service (QoS) – Voice over IP (VoIP) – Routing multiple Layer 3 Basic Network Media Required to Make a LAN Connection Học viện mạng Bách khoa - Website: www.bkacad.com – Routing multiple Layer 3 protocols – Special services such as NAT and DHCP • The budget is an important consideration. The media used to connect to the router should be supported without needing to purchase additional modules.
