4 Learning Tool: eNSP
eNSP (Enterprise Network Simulation Platform) is a graphical network simulation tool which is developed by
Huawei and free of charge. eNSP mainly simulates enterprise routers, switches as close to the real hardware as
it possible, which makes the lab practice available and easy without any real device.
In addition, Huawei has built up Huawei Technical Forum which allows candidates to discuss technical issues with
Huawei experts , share exam experiences with others or be acquainted with Huawei Products(

identical attachment file names, you are advised to include the software package name in theattachment file path. For example, if the software package name is a, set the attach file path to /opt/install/a on Linux and to c:\install\a on Windows.

To install non-ISO application software for a VM template, you need to copy the application software package savedon the PC to the VM in shared mode, and install the package on the VM. Therefore, check that at least one NIC onthe VM belongs to the service plane. That ensures that the VM can be automatically allocated an IP address that cancommunicate with the PC. If the VMware Hypervisor is used, delete the NIC configuration after installing non-ISOapplication software and before publishing the VM template. If the VMware Hypervisor is used, click ChangeStartup Mode to change the startup mode to boot from the CD-ROM drive.
If yes, go to step 11.
If no, go to step 25.

Installing an OS
Step 25 Set the OS parameters about the VM template as prompted based on the data plan.
If the FusionCompute Hypervisor is used, you can mount the CD-ROM drive in shared mode. Alternatively, you
can click VNC login, click on the VM, and then select File (*.iso) to mount the CD-ROM drive. Thisdocument uses the shared mode as an example when describing the detailed steps.
If the VMware Hypervisor is used, CD-ROM drives cannot be mounted using a locally shared file. An NSFserver must be configured in the vCenter to communicate with the FusionManager and mount CD-ROM drives.
If you click Close on the Software Installation page, the system asks you whether to save the VM template being created. If you save the VM template as prompted, the VM information can be searched for on the VM
Template page. To continue the installation, click .
When installing an OS, select Restart the VM immediately after mounting the ISO file.
Step 26
Click Mount.
The Mount dialog box is displayed.
A host allows only one VM template to have a CD-ROM drive mounted. Therefore, if you want to exit the SoftwareInstallation page when no software is being installed for the VM template, click Detach to unmount CD-ROM
drive from the VM first. If the VMware Hypervisor is used and the unmounting fails, click VNC login, eject theCD-ROM drive, and try again.

This mode cannot be enabled for disks that do not support thin provisioning. Check the availability ofthin provisioning in the following way:
1. Choose Resource > Resource Pool.
The Resource Pool page is displayed.
2. Choose Data Center > Data Center > Zone > Computing Resource Pool > Resource cluster.
The Summary page is displayed.
3.
On the Storage page, check whether there are storage devices that support thin provisioning.
− If yes, enable or disable thin provisioning.
− If no, do not enable thin provisioning.
− Affected by snapshot: If this option is selected and the system is taking a snapshot for the VM,no snapshot is taken for the disk.
When setting the computer name, you can enter a desired one or click to reference a public parameter.
Step 15 Expand the Software list in the area on the left, and drag the software package into the VM template.
If there is no available software package, you can log in to the VNC and mount a CD-ROM drive to install anISO piece of software. If you want to install a non-ISO piece of software, copy the software installation file tothe VM and install it.
The OS type suitable for the software must be in compliance with that of the VM.
When multiple software packages need to be added to the VM template, they must be dragged to the VMtemplate in sequence from the area on the left.
The software packages in the VM template must be installed from bottom to top.
If the target OS is Windows XP 32-bit, install the NIC driver and SCSI controller driver for the VM. The driversare available at:

If only the default NIC is available for configuring the VM template NIC, the Add Association dialog box is notdisplayed when adding the association between the VM template and the port group.
If yes, go to step 21.
If no, go to step 23.
Step 21 From the NIC drop-down list, select a NIC.
Step 22 Click OK.
The association between the NIC and the network is added.
Step 23
Determine whether to add the association between the other NICs and the network.
If yes, perform step 17 to step 22.
If no, go to step 25.
Each VM NIC can be associated with only one network. If you need to associate multiple NICs with the network,add the same number of networks as the number of NICs, and associate each NIC to one network.
Step 24 Determine whether to add an elastic group.
If yes, go to step 25.
If no, go to step 32.
Step 25
Expand ScalingGroup in the area on the left, and drag the default elastic group into the operation area.
After the elastic group is created, you can set the inter-group policy of elastic groups in the VDC toimplement resources scheduling in the VDC.
Step 26 Step 26: Set the elastic group parameters in the area on the right.

eNSP (Enterprise Network Simulation Platform) is a graphical network simulation tool which is developed by
Huawei and free of charge. eNSP mainly simulates enterprise routers, switches as close to the real hardware as
it possible, which makes the lab practice available and easy without any real device.
In addition, Huawei has built up Huawei Technical Forum which allows candidates to discuss technical issues with
Huawei experts , share exam experiences with others or be acquainted with Huawei Products(
