Join Greg Sowell for an in-depth discussion in this video Ping, Tracert, PathPing, part of Networking Foundations: Protocols and CLI Tools.
- When troubleshooting network connectivity,…the next step after verifying ip information with ip config,…is to use the Ping utility.…If a client is having trouble getting out to the internet,…or just on the network,…I'll first ping it's default gateway.…From the command line, I'll simply type…ping, and the ip address of the default gateway.…10.3.25.1…By default, it will issue four pings,…and uses 32 bytes per ping,…reporting the latency of each ping,…measured in milliseconds.…
This is also known as the round trip time,…since it measures how long it takes the packet…to reach the destination and return.…When the four pings are complete,…statistics like how many packets were sent,…and how many returned,…as well as the minimum, maximum, and average…latency for the packets are displayed.…Sometimes, four pings isn't enough to troubleshoot…intermittent connectivity issues.…To persistently ping a host, I'll type,…ping - t, and the ip address.…
10.3.25.1…It will continuously ping showing latency,…and possible packet loss.…
Protocols are the lifeblood of modern communication. By the end of this course, you'll know what you need to troubleshoot any network connection and keep the communication flowing.
Note: This course maps to domain 3 of the MTA Networking Fundamentals exam.
- Identify reasons why connectionless transmissions are faster.
- Determine what type of attack a gratuitous ARP announcing itself as a legitimate host indicates.
- State what IGMP snooping is useful for.
- Describe the best approach to use FTP to view and rename files on a server when your client is behind a firewall.
- Assess whether SSH is natively supported on Windows or not.
- List good uses for the arp command.
