Licensing Maps to Exams. Boson's licensing model is cumulative just like Cisco certification levels. Each Boson license maps specifically to a Cisco certification exam, and includes the labs for the preceding exams, too.
This licensing model is easy to understand, relatively affordable, and provides a large number of built-in labs for each exam. If you find structure important, this is really convenient. Lab Quality. While the number of labs you receive depends on the price, every Boson lab is high quality and tailored to a Cisco certification exam. Each lab comes with detailed instructions regarding what needs to be configured and verified within the related network topology. Furthermore, most labs ask insightful questions about the output of commands observed in the CLI of the networking device, which helps reinforce understanding about what is being configured and why it needs to be configured.
Just like Packet Tracer, each lab is graded for completion and accuracy within the application. However, where Boson NetSim differentiates itself from Packet Tracer is the ability to track completion of labs from within the application.
This feature allows you to view your completed labs, attempted labs, and un-attempted labs at a glance. It is worth noting here that Cisco's NetAcad courseware also offers labs through Packet Tracer exercises as well as hands-on labs with physical equipment. However, the focus of this article is reviewing the Packet Tracer software itself, not the NetAcad courseware. Boson's software revolves around purchased lab activities in addition to a sandbox.
This is a feature and advantage that NetSim holds over Packet Tracer, which requires your to either get creative or source labs from NetAcad. Lab Accessibility. All purchased Boson labs are easily accessible from within the application, unlike Packet Tracer. There is no need to download labs through individual files and import them into NetSim — all labs are downloaded, completed, and graded from within the application itself. This lets you focus your time on labbing exam topics rather than downloading files and setting up the lab.
Custom Lab Distribution. If you create a network topology that you'd like to share with the world, you can easily upload the topology to the NetSim Community.
Conversely, you can browse other people's uploaded topologies and download them from within the application. As previously mentioned, there is no need to download a separate topology file and import it as is done with Packet Tracer. Realistic Terminal Features. Copy and paste is very realistic in NetSim. In a real terminal, highlighted text is automatically copied to the system clipboard.
You paste with a right-click. NetSim's terminal mimics this function. This realistic feature sets NetSim apart from Packet Tracer, where this is not supported. By default, terminals are tabbed, so each device's terminal appears within its own tab, unlike Packet Tracer where each terminal gets its own window.
If this is not desired, you may place a tab in its own window by right-clicking the tab and selecting the "Float" option. Alternatively, you can drag the tab outside of the terminal window to accomplish the same task.
In fact, the entire interface of NetSim boasts this UI — just about every window can be docked and undocked with ease so that the interface is customized to suit your preferences. In NetSim, if a network device can be customized through the addition of modules which it calls "Addons" , the software explicitly asks what modules you would like to insert in the device when the device is added to a network topology. Additionally, NetSim calls out the type of interfaces that each module adds.
For example, if you want to add an HWIC-2T network module to a device, NetSim explicitly tells you that the addition grants two additional serial interfaces that the device can use. Finally, once a device has been customized and added to the network topology, a device with the same physical configuration is saved in the "Recent Devices" window. This modified device can be easily added to the topology by dragging it from the "Recent Devices" window into the network topology.
Less clicking than Packet Tracer. In Packet Tracer, you must place a device in your network topology, manually power off the device by clicking on the power switch , drag the desired network module to the desired slot, then manually power on the device by clicking on the power switch. Furthermore, this process needs to be repeated for each device that needs its physical configuration modified. If you need to test a topology in Packet Tracer with eight routers using serial interfaces, modifying each device results in a lot of clicking.
Lack of Topology Information. The network topology window shows a limited amount of information, especially while a simulated topology is running. For example, you can't see the link state of each connection between network devices, nor do you have any indication that the device is actively transmitting data.
The primary source of feedback for this type of information is the device itself. While this could help prepare you for a role as a remote network administrator where physical access to devices is not possible, the additional feedback in simulation would be particularly helpful for visual learners. Lack of Topology Customization. Unlike most other network simulators and emulators, NetSim does not have a way to add colorized shapes to a network topology. Aside from network devices and connections, you can only add text-based notes and labels to the topology.
This is a fairly minor point, but is important when rehearsing some exam topics, such as multiarea OSPF, where colored shapes illustrating the different areas comes in very useful. Cannot Modify Active Topology. Once a network topology is running, you can't modify it until you stop the topology, which shuts down the simulated network devices.
If you need to add a new network device or a new connection to your network topology, you must stop the entire topology, modify it as needed, then start the topology once more.
This is a minor point, as the topology itself starts and stops very quickly, but the less time you spend managing simulator, the better! No Simulation Mode. There is no way to place NetSim's network topologies into a "simulation mode" like one can with Packet Tracer. There is no way to view the contents of individual packets as they traverse the network in NetSim.
All network devices are simulated in real-time. As a result, you can't visualize the path of a packet throughout your simulated network the same way that you can in Packet Tracer. No Cross-Platform Compatibility. It is not supported on macOS or any Linux distribution. Boson NetSim's strongest feature is the built-in labs that directly map to the exam topics of specific Cisco certification exams. For existing patrons of Boson's courseware and practice exams, these labs are an excellent practical aid for reinforcing networking concepts.
The fact that labs whether they were built by Boson or built by the community can be accessed directly through the NetSim application simplifies the labbing experience and lets you focus on learning instead of prerequisite tasks. The software's weakness is in the creation, manipulation, and interaction of network topologies in the sandbox environment. It is more difficult to create aesthetically-pleasing network topologies in NetSim compared to other network simulators and emulators.
An active network topology does not provide very much visual feedback regarding the status of devices, links, and transmission of data.
NetSim's simulated Cisco IOS software has small quirks not exhibited by actual Cisco IOS software, particularly when using context-sensitive help or executing non-existent commands, which is a common mistake that many networking novices make.
Finally, while NetSim's terminal emulator has some features that cannot be found in Packet Tracer's terminal emulator, Packet Tracer's wider support for keyboard shortcuts presents a more tactile CLI experience. Now that we have reviewed the two pieces of network simulator software offered on the market, let's dive into emulators!
An emulator is a piece of software that runs and connects virtual network devices together. Please follow how to table which qcow2 output fileneame must be.
