How do I trace a ping? Type PING in the command dialogue window. Hit the space bar once. Type the IP or website address that you want to ping. Hit "Enter" or return on your keyboard. What OSI layer is Sonet? Short for Synchronous Optical Network, a standard for connecting fiber-optic transmission systems. The standard defines a hierarchy of interface rates that allow data streams at different rates to be multiplexed.
What layer is Telnet? Application Layer. It is the part of the IP service that acts as the feedback system in network IP communication, making sure that undeliverables packets are reported to the sending host, such as the router or the gateway. Any IP network device can send ICMP datagrams, including network interface cards and other devices that are commonly used in your environment.
The manufacturer is sending the parts one by one, assuming that they are being received by the assembly crew. Occasionally, though, a part does not arrive as scheduled, or parts are being slowed down via their usual delivery method and a faster way of getting parts to assembly exists. The assembly crew needs a way to notify the manufacturer to resend the missing part or to send the parts via a different, faster shipper or route.
This protocol is a fairly complex. Now let us know how each layer of an OSI model works for the transmission of the data? The network layers use the Internet protocol, address resolution protocol, and Internet control message control protocol. The network layer routes the data to the different paths of the network.
Different protocols are used for different communication in the network. The gathering of all these protocols can call as the Internet protocol. The Internet layer directly maps to the network layer and the last two layers of the OSI model. The ICMP stands for the internet control message protocol. It is present in the network layer of the OSI model. Typically, we do not have any errors present in the IPV4 protocol. The basic primary function of the ICMP is to report the errors in the data.
Another function is network diagnostics. The commonly used network diagnostics are traceroute and ping. If you encounter a technical issue on the site, please open a support case.

All the joys. HTH, Garry ,. I really doubt. Hope this helps. Kind Regards, Garry. HTH, Scott haha, good thing you weren't drinking or you would have been fist fighting about it. There is a video on CNL describing both. Hi biplab, ARP runs on top of layer 2 protocol, i. Kind Regards, Garry Message was edited by: Garry.
For example, - Ethernet and PPP runs directly on a layer 2 of the OSI model for instance, Ethernet using the transport services of layer 1 electrical signal transmission and providing the transport services for layer 3 IP and layer 2. Gary, I don't disagree with your logic. Sorry if this just adds to the confusion. In exam you should answer ARP is layer3. HTH Brian.
Thanks for the replies, -Trent. Didn't read the book correctly. Thanks for the contributions to this question. I love this thread. Is everyone on the same page now? Please correct me if I am wrong. The internet module prepares a datagram header and attaches the data to it. The internet module determines a local network address for this internet address, in this case it is the address of a gateway. It sends this datagram and the local network address to the local network interface.
The local network interface creates a local network header, and attaches the datagram to it, then sends the result via the local network. Hi, Scott. I'm sorry but I have to disagree with you. We cannot this too much about it On this forum we want to hear the "right answers" for Cisco exams. Hi, Jean, I'm afraid Cisco will not appreciate "your one cent". Please, stop confusing other people. It is not my intention to confuse anyone.
I am sorry if you feel offended by my opinion. Hi, Jean, It's alright, man I'm not offended. Hello Jean, You may be in this forum to learn as the rest of us are, granted. Preet I get it. Let, s move on. No hard feelings! Any thoughts on the layer question for ICMP? Hello John, Once knowldge in networking reaches a significant level of 'comfort', one ofcourse tends to avoid or simply brush aside questions pertaining to the layering models.
Someone brought donuts?!?!?!?!

Hi, Jean, I'm sorry, didn't mean to offend you. We are here to learn. Today I learned my lesson the hard way. But at least I did it. My sincere apologies. Preet, So are your car keys regarded as part of you or as part of your car?
Sarah, Thank you for the note, but I didn't take it personally! I submit, your reasoning does make complete sense. No problems! I'm sorry, Brian, but I have to disagree with you.
Cheers, Scott. Hi, Scott, Hands up! You are right. I guess I just got confused by my study guide.
