Example for Creating VSs

This section provides an example for creating VSs and allocating resources to the VSs.

Networking Requirements

This configuration example is supported only on the Admin-VS.

On the network shown in Figure 1, the IPU of a PS processes all services offered by an SP. If a service failure on the PS causes a PS failure, other services running on the PS cannot be properly forwarded. To prevent this problem, configure different VSs on the PS to independently carry services to improve network security.

As shown in Figure 1, different VSs can be created on a PS. The VSs carry their own services that are mutually isolated. Services can be quickly differentiated by VS, and physical interfaces can be shared between the VSs, saving physical links and reducing networking costs.

Figure 1 Creating VSs

Precautions

When creating VSs, note the following points:

A VS starts after it is created.
The VS slot resources can be allocated only by the PS administrator.
The same slot resources can be allocated to multiple VSs.
A physical interface can be allocated only to one VS. That is, a physical interface cannot be shared by different VSs.
The slot resources deleted from a VS are automatically allocated to the Admin-VS, and the Admin-VS takes over services carried using these slot resources.

Configuration Roadmap

The configuration roadmap is as follows:

Create VSs and configure PVMBs for each VS so that the VSs can start.
Allocate interfaces to VSs to allow the VSs to forward services.

Data Preparation

To complete the configuration, you need the following data:

Names of the VSs to be created: vs1, vs2, and vs3
Interface number allocated to each VS

Procedure

Create and start VSs.

<HUAWEI> system-view
[~HUAWEI] admin
[~HUAWEI-admin] virtual-system vs1
[*HUAWEI-admin-vs:vs1] port-mode port
[*HUAWEI-admin-vs:vs1] description vs1
[*HUAWEI-admin-vs:vs1] quit
[~HUAWEI-admin] virtual-system vs2
[*HUAWEI-admin-vs:vs2] port-mode port
[*HUAWEI-admin-vs:vs2] description vs2
[*HUAWEI-admin-vs:vs2] quit
[~HUAWEI-admin] virtual-system vs3
[*HUAWEI-admin-vs:vs3] port-mode port
[*HUAWEI-admin-vs:vs3] description vs3
[*HUAWEI-admin-vs:vs3] quit
[*HUAWEI-admin] commit

Allocate resources to the VSs.

[~HUAWEI-admin] virtual-system vs1
[*HUAWEI-admin-vs:vs1] assign interface gigabitethernet 0/1/18
[*HUAWEI-admin-vs:vs1] quit
[~HUAWEI-admin] virtual-system vs2
[*HUAWEI-admin-vs:vs2] assign interface gigabitethernet 0/1/19
[*HUAWEI-admin-vs:vs2] quit
[~HUAWEI-admin] virtual-system vs3
[*HUAWEI-admin-vs:vs3] assign interface gigabitethernet 0/1/20
[*HUAWEI-admin-vs:vs3] quit
[*HUAWEI-admin] commit

Configure different services or features on the VSs.
For configuration details, see the related feature configurations. For example, to configure a routing protocol on VS1, see the chapter "IP Routing" in the NetEngine 8000 F Configuration Guide - IP Routing.

Verify the configuration.

Run the display virtual-system command on the PS. The command output shows that vs1, vs2, and vs3 have been created and started.

[~HUAWEI-admin] display virtual-system
---------------------------------------------------------------
Name                             Status         Description
---------------------------------------------------------------
Admin-VS                         running         admin-vs
vs1                              running         vs1
vs2                              running         vs2
vs3                              running         vs3
---------------------------------------------------------------

Run the display virtual-system [ name vs-name ] [ verbose ] command on the PS. The following example uses vs1 configurations.

[~HUAWEI-admin] display virtual-system name vs1 verbose
Name         : vs1
Status       : running

m6route      : 1000(Max)
vpn-instance : 256(Max)
cpu          : 5(weight)

Run the display virtual-system configuration state command on the PS to check whether VS configurations have been saved.

[~HUAWEI-admin] display virtual-system configuration state
-----------------------------------------------------------------
Name                             Saved-configuration

vs1                              not saved                       
vs2                              not saved                       
vs3                              not saved
