This week we learned about advanced routing switching. This course requires the use of a HCL simulator. The following are the difficulties encountered in the simulator installation project and the experience of using it.

Installation problems:

Problem: starting HCL simulator pops up a log error dialog box, unable to start HCL simulator

Solution: after looking for answers online, it is found that it is a compatibility problem. Right-click the properties of the HCL simulator, find the compatibility, select Windows7 or Windows8 or Windows Vista, and the application will run normally.

Experience of using:

After installing the simulator, compare with Cisco's simulator.

Interface:

Pros: the interface is found to be more comfortable and simpler than Cisco's.

Features:

Advantages: 1. The simulator integrates virtualbox, which can be used in the experiment that the simulator is directly connected to the real equipment.

two。 You can use your own DIY device (although you don't know what's the use)

3. Shutting down the cloud platform is equivalent to a power outage, and the configuration information will be cleared, which makes us form the good habit of saving the configuration at any time.

Disadvantages: 1. Without the sending process of the data packet, it is not conducive to understand the transmission principle of the data packet. two。 There is one kind of switch, which does not distinguish between two and three layers, and the situation of the equipment is too single, which is not conducive to the mastery of different devices. 3. The device starts slowly.

Performance:

The need for computer configuration requirements is higher than Cisco's, at least need 4G storage to start, and the installation process is relatively cumbersome, but also more prone to some problems.

Note:

1. For the latest version of Windows operating system, such as Windows 10 system to install HCL simulator error, it is necessary to adjust the Windows system compatibility so that the system supports HCL simulator.

During the installation of 2.HCL simulator, if the virtual device starts slowly after starting HCL, or if you open the command line configuration interface without any information, you need to consider whether the PC or server on which HCL emulator is installed has the VT-X feature turned on. (VT-X is cpu virtualization in hardware-assisted virtualization, a full virtualization technology that allows physical hardware devices to support virtualization). PC or server enters BIOS and opens CPU virtualization.
