CCNA Industrial Training Presentation

  1. 1. In 1984 Computer scientists, Len Bosack and Sandy Lerner, from Stanford University, found Cisco Systems. They invented this technology to link their computer systems together. • In 1984 Computer the worldwide leader in networking Cisco Systems, Inc. isscientists, Len Bosack and Sandy Lerner, from Stanford University, found Cisco an essential part of for the Internet. Today, networks are Systems. They invented this technology to government and home business, education,link their computer systems together. • Cisco Systems, and the worldwide Protocol-based (IP) communications,Inc. isCisco Internetleader in networking for the Internet. Today, networks are an essential part of networking solutions are the foundation of these business, education, government and home communications, networks. Internet Protocol-based (IP) networking solutions and Cisco Cisco hardware, software, and service offerings are used are the foundation of these networks. to•create hardware, solutionsand service offerings are used to Cisco Internet software, that allow individuals, companies, and countries that allow individuals, companies, create Internet solutions to increase productivity, and customer satisfaction and strengthen improvecountries to increase productivity, improve customer satisfaction and strengthen Cisco name has become competitive advantage. The competitive advantage. The Cisco name has become synonymous with the Internet, as synonymous with the Internet, as well as with thewell as with the productivity improvements that Internet business productivity provide. solutions improvements that Internet business
  2. 2. • An Internet Protocol address (IP address) is a numerical label assigned to each device participating in a computer network that uses the Internet protocol for communication. • Ip address must be unique in a network. • Ip address is read with its Subnet mask. • 32 bits( 0 or 1) divided into 4 octets. • Ip address has two portions – network and host. • Each octet has a decimal value ranging from 0 to 255, except for the first octet which is 1 to 255. • The first octet cannot be 127 , this is reserved for loopback and also to check if protocol stack is correctly configured. • All 0’s define network address. • All 1’s define broadcast address. • The ip address 255.255.255.255 defines a general broadcast.
  3. 3. • Classless Inter-Domain Routing (CIDR) is a method for allocating IP addresses and routing Internet Protocol packets. The Internet Engineering Task Force introduced CIDR in 1993 to replace the previous addressing architecture of classful networkdesign in the Internet.Its goal was to slow the rapid exhaustion of IPv4 address. • CIDR values tells about the ON bits for example:255.224.0.0/11 -> 11 bits are on 255.255.192.0/18 -> 18 bits are on Maximum range is /30 because 31 & 32 are reserved for hosts.
  4. 4. Telnet: It is a service through which we can access one pc from another pc in command mode. FTP: A method of transferring one or more file from one system to another system over a network. TFTP: It is stack version of FTP. TFTP has no browsing ability. It can send and receive files. NFS: It is a service through which we can transfer data and files from linux to linux or linux to window. SMTP: Simple mail transport protocol, through this mail can be sent. DNS:It translate name to IP or Ip to names. DHCP: It is used to give IP to client automatically.

  8. 8. POST(Power on Self Test) ROM(Mini IOS) present -> not present->rommonmode FLASH(IOS) check config NVRAM yes, setup mode no, extended mode ctrl + c
  9. 9. • User mode-allows user to perform few commands, configurations cannot be changed. • Priviledge mode- It enables user to view and change few configurations. • Global configuration mode- It allows user to change those configurations which effects the working of router.
  10. 10. User mode Priviledge mode Global configuration mode
  11. 11. • Static routes are user defined manually created routes.The administrator creates creates static routes in cisco routers using Ip route command. • Syntax:ip route destination network subnet mask next hop router ip address • Example:• Ip route 11.0.0.0 255.0.0.0 10.0.0.2
  12. 12. • Default routes define a router as the default router. When there is no entry for the destination nettwork in the routing table, the router will forward the packet to its default router.Default router help in reducng the size of your routing table. • Syntac: ip route 0.0.0.0 0.0.0.0 next hop router • Example • Ip route 0.0.0.0 0.0.0.0 10.0.0.2
  13. 13. • • • • • • • • Classfull Open standard Metric: Hop count(15) Distance vector protocol Max path=4(16) [equal load balancing] Broadcast:255.255.255.255 Port no 520 Send update every 30 seconds.

  15. 15. • Cisco proprietary routing protocol • Advanced distance vector/ hybrid routing protocol with features such as dynamic neighbor discovery. • Classless/ VLSM • Metric: bandwidth, delay, load, reliability • Hop count 255 • Multicast 224.0.0.10
