  1. JETKING Cisco Certified Network Associate

  2. It have been the first institute for training non technical students set up in 1990. Jetking has come a long way today with over 100 training centers, 2500 faculty members, international academic partnerships and ISO 9001:2000 certification since 2003 COMPANY PROFILE

  3. A computer network is a group of interconnected computers TYPES OF NETWORK Personal area network(PAN) Local area network(LAN) Campus area network(CAN) Metropolitan area network(MAN) Wide area network(WAN) NETWORK

  4. NETWORK TOPOLOGIES BUS TOPOLOGY STAR TOPOLOGY RING TOPOLOGY MESH TOPOLOGY

  5. NETWORK DEVICES • Lan card:- • The network interface card(NIC) used as interface between the device and the network. • It has Buffer memory. • Memory of LAN card is 1024 byte. • Lan card is used for both transmission and receiving of data • MAC address is physical or hardware address. • Size of MAC address is 48 bit RJ-45

  6. Hub • Hub is a layer 1physical layer device. • Hub provides data transfer rate (D.T.R)= 10 mbps maximum. • Hub works on half duplex mode • Hub is used over a small LAN network.

  7. Switch • Switch is a layer 2(data link layer) device. • Switch is a LAN device. • Switch understands MAC address. • Switch is used to design a large and complex network. • Switch improves network performance and speed. • Switch works on full duplex mode i.e both sending and receiving data at the same time.

  8. ROUTER • It is used for wan connectivity. • Router is a layer-3 (network layer) device. • Routers are used to interconnect different wan sites. • Router is a IP and routing enabled device. • Router only understands logical address i.e IP address. • Router uses a routing table which maintains shortest and best path for each destination.

  9. OSI MODEL(Open Systems Interconnection Basic Reference Model ) • 7) Application : Provides different services to the applications • 6) Presentation : Handles the format of different applications and files • 5) Session : Responsible to make logical connection b/w application and server • 4) Transport : Provides end to end communication control • 3) Network : Routes the information in the network • 2) Data Link : Provides error control between adjacent nodes • 1) Physical : Connects the entity to the transmission media

  10. IP ADDRESS • An Internet Protocol (IP) address is a numerical identification (logical address) that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. Although IP addresses are stored as binary numbers, they are often displayed in more human-readable notations, such as 192.168.100.1 (for IPv4), and 2001:db8:0:1234:0:567:1:1 (for IPv6). • IP address was defined as a 32-bit number and this system, now named Internet Protocol Version 4 (IPv4) , a new addressing system (IPv6), using 128 bits for the address An IP address is designed with two parts:- • Network:- net-id • host:- host-id

  11. Different classes of IP version 4 • Class A:- 8 bit for network and 24 bit for host. First block consists of Network bits from 1-126. Mask value is 255.0.0.0 • Class B:- 16 bit for network and 16 bit for host. First block consists of network bits from 128-191. Mask value is 255.255.0.0 • Class C:- 24 bit for network and 8 bit for host. First block consists of network bits from 192-223. Mask value is 255.255.255.0 • Class D:- It is used for video conferencing . First block consists of network bits from 224-239. • Class E:- It is used for voice conferencing . First block consists of network bits from 240-254. • Special IP(Reserve IP):- • 127.0.0.0:- This IP is called loopback or local host IP. It is used for self testing or trouble shooting. Its command is C:> ping 127.0.0.1 • 255.255.255.255:- This IP is called Broadcast IP and used in lan broadcasting. • 169.254.0.0:- It is called APIPA(automatic private IP address).

  12. IP Addressing

  13. IP Address Classes

  14. NAT(Network Address Translation) STATIC NAT DYNAMIC NAT NAT is a layer 3 protocol and it use to translates public IP into private and private IP into publicPRIVATE IP ADDRESS: - CLASS A-----10.0.0.0---------10.255.255.255--------10.0.0.0/8 CLASS B-----172.16.0.0------172.31.255.255--------172.16.0.0/12 CLASS C-----192.168.0.0----192.168.255.255-------192.168.0.0/16

  15. ROUTER FUNDAMENTALS Modes of router:- • Router memory types • Router booting process and registered numbers • Router interface and ports • IOS(internet operating system) • Consol pc User mode Privilege mode Global mode Interface mode

  16. Overview of Router Modes

  17. Configuring Router Identification

  18. Configuring a Router Password

  19. Static Route Uses a route that a network administrator enters into the router manually Dynamic Route Uses a route that a network routing protocol adjusts automatically for topology or traffic changes Identifying Static and Dynamic Routes

  20. Static Routes

  21. PROJECT USING STATIC IP ROUTING

  22. Mumbai>enable Mumbai#configure terminal Mumbai(config)#Ip route 30.0.0.0 255.255.255.0 20.1.1.2 Mumbai(config)#Ip route 20.1.1.4 255.255.255.252 20.1.1.2 Mumbai(config)#Ip route 40.0.0.0 255.255.255.0 20.1.1.2 Mumbai(config)#Ip route 50.0.0.0 255.255.255.0 20.1.1.2 Mumbai(config)# exit Mumbai# Banglore>enable Banglore# configture terminal Banglore(config)#ip address 40.0.0.0 255.255.255.0 20.1.1.9 Banglore(config)#ip address 20.1.1.4 255.255.255.252 20.1.1.9 Banglore(config)#ip address 30.0.0.0 255.255.255.0 20.1.1.9 Banlore(config)#ip address 20.1.1.0 255.255.255.252 20.1.1.9 Banglore(config)#ip address 10.0.0.0 255.255.255.0 20.1.1.9 Banglore(config)#exit Project code

  23. PING • Ping is a command used to test the connectivity and troubleshooting states between the network devices over a network. Its syntax is:- • Router#ping Ip address • If the device is connected (!!!!!!) • If not connected (…….)
