Name: Navinder Singh Batch :A2 UID: 2020200058 EXPERIMENT-
Aim: Study and demonstration of basic network command and Network configuration
commands.
Apparatus (Software): Command Prompt/terminal and Packet Tracer.
Procedure: To do this experiment- follows these steps:
Part I
In this EXPERIMENT- students have to understand basic networking commands and its significance in computer network perspective. Install operating system and demonstrate the following commands Windows OS Use the command prompt and type each command and interpret the significance in CN ● Ping ● Pathping ● NetStat ● ARP ● NbtStat ● Hostname ● Tracert ● IpConfig ● IpConfig/ all ● NSLookup
Theory
- Ping Ping is a command-line utility, available on virtually any operating system with network connectivity, that acts as a test to see if a networked device is reachable. The ping command sends a request over the network to a specific device. Ping is used to check connectivity between two end devices or from host to client. It is done by transmitting and receiving data packets from one device to another. Any error in connectivity is indicated as a loss in packet.
- Pathping It provides information about network latency and network loss at intermediate hops between a source and destination. This command sends multiple echo Request messages to each router/switch between a source and destination, over a period of time, and then computes results based on the packets returned from each router. Pathping indicates addresses of spots that have network loss or latency.
- NetStat
Nbtstat displays protocol statistics and current TCP/IP connections using NBT (NetBIOS over TCP/IP), which helps troubleshoot NetBIOS name resolution issues. It displays all connections of the computer such as bluetooth, ethernet and wifi connections.
- Hostname It displays the name of the computer in the networks such as Local Area Network.
- Tracert
The tracert command is a command that is used to show several details about the path that a packet takes from the computer or device you're on to whatever destination you specify. It displays the number of hops, delays a data packet takes to reach the destination from the source. It also gives addresses of the intermediate computers.
- IpConfig IPconfig is a console application designed to run from the Windows command prompt. This utility allows you to get the IP address information of a Windows computer. It also allows some control over your network adapters, IP addresses (DHCP-assigned specifically), even your DNS cache. It is used to configure the IP settings of the devices. It is used to change, view IP addresses, gateway and subnet masks of all the TCP/IP connections on the device.
- IpConfig/ all
Nslookup is the name of a program that lets an Internet server administrator or any computer user enter a host name (for example, "whatis.com") and find out the corresponding IP address or domain name system(DNS) record. The user can also enter a command for it to do a reverse DNS lookup and find the host name for an IP address that is specified. It gives IP addresses for a given domain from the Domain Name System cache.
Conclusion:
● Studied various network commands of Windows command prompt such as ping, tracert, nslookup, etc. Also, learned their significance as a command. ● Ran these commands on windows and linux systems and compared them.
Part II
All commands related to Network configuration which includes how to switch to
privilege mode and normal mode and how to configure router interface and how to save this configuration to flash memory or permanent memory. This command includes
Tasks:
● Configuring the Router commands
- interface
- ip address
- description
- no shutdown ● General Commands to configure network A. enable B. config -t C. password D. login E. exit ● Privileged Mode commands of a router It allows the user to configure the router, that is, change its ip settings. It is accessed by using the enable command. ● Router Processes & Statistics ● IP Commands
Demonstrated output
Conclusion:
