When a router, switch, NIC or any other hardware component goes down, your job as a network technician includes identifying the location and the cause of the network failure or performance issue. Even on smaller networks, it can be a challenge to determine exactly which network component is causing problems. Describe in detail (1-2 Pages) how would you use the various TCP/IP troubleshooting tools (ping, traceroute, netstat..) to identify connectivity and/or network response issues. If the problem appear to come from a particular workstation or server on the network, describe the steps that you will take to identify the hardware or software component that is creating the problem. hint: Don't use google
As a network technician, it's essential to know how to use various TCP/IP troubleshooting tools to identify connectivity and network response issues.
The following are some of the tools that can be useful in this regard:
1. Ping:
Ping is a command-line tool that tests the reachability of a network host by sending an Internet Control Message Protocol (ICMP) echo request and waiting for a response.
By using ping, a technician can determine if a network host is responding, the round-trip time for packets to travel to and from the host, and the packet loss rate.
2. Traceroute:
Traceroute is another command-line tool that identifies the path taken by packets sent from a source to a destination.
It helps to identify the devices on the path and the time taken by each device to forward the packets.
By using traceroute, a technician can identify network congestion, packet loss, and misconfigured routers.
3. Netstat:
Netstat is a command-line tool that displays the active TCP/IP connections and their status. It helps to identify open ports, established connections, and the current state of the connections.
By using netstat, a technician can determine if a network host is listening on a specific port, the number of active connections, and the state of those connections.
