Layer 1 2 3 Network Diagram

Thank you for any responses in advance.

Layer 1 2 3 network diagram. Generally speaking layer 2 is a broadcast media access control mac mac level network while layer 3 is a segmented routing over internet protocol ip network. After that comes a layer 1 diagram showing physical layouts of the devices. In this first article we show you how to take advantage of visio layers to display different network informations l1 l2 l3 routing configuration on the same sheet without overload the network diagram. You can edit this network diagram using creately diagramming tool and include in your report presentation website.

Layer 2 data link examples include ppp fddi atm ieee 802 5 802 2 ieee 802 3 802 2 hdlc frame relay. The layers refer to how you configure an it network and the standard for network communications called the osi model. Physical layer 1 osi model layer 1 conveys the bit stream electrical impulse light or radio signal through the network at the electrical and mechanical level. Then i make a layer 2 diagram showing the switch connections trunks and lacp channels.

For network engineers and architects understanding the difference between a layer 3 and layer 2 network can greatly enhance the overall security and speed of your network infrastructure. Layer 1 defines the electrical mechanical procedural and functional specifications for activating maintaining and deactivating the physical link between end systems. The reason we are having a discussion about layer 2 or layer 3 is that your choice of either layer has advantages and disadvantage in terms of. Layer 2 data link.

It s responsible for packet forwarding routing and addressing. Latest ssl version 1 nat 3 network 3 network security 2 networking basics 14. Osi layer 2 3 to add a third layer with vlans and ip addresses. The pdu is passed to layer n 1 where it is known as the service data unit sdu.

At layer n 1 the sdu is concatenated with a header a footer or both producing a layer n 1 pdu. Actual hardware sits at this layer. Layer 2 and layer 3 refer to different parts of it network communications. I usually start with a layer 3 network diagram to show the routing and ip subnets.

It s also a good idea to make a separate diagram for each network protocol layer. Network diagram and visio layers 1 2 par ttrupel le 27 03 2016 16 59. Can you tell me where i can find layer 1 layer 2 and layer 3 network diagrams. A network diagram showing layer 2.

This layer determines how data is sent to the receiving device. It is then passed to layer n 2. It seems to me that companies project different ideas of what should be displayed in each diagram. The process continues until reaching the lowermost level from which the data is transmitted to the receiving device.
