Creating a Virtual Network (vNET)
To separate resources, including switch ports, IP addresses, VLANs, and VXLAN IDs into separate management spaces, create a vNET(s) and associate the desired resources to it (see below for an example of configuration).
You can create a vNET using the vnet-create command followed by a list of required parameters. Subsequently, you can configure a separate vNET administrator to manage each newly created management domain.
CLI (network-admin@switch) > vnet-create
name name-string |
Defines the virtual network (vNET) name. Enter a name for identification of this vNET. |
scope local|cluster|fabric |
Defines the scope of this vNET. Use fabric scope if this vNET should be seen by all switches. If this vNET should not be seen by other switches, use cluster or local scope. |
Specify one or more of the following options: |
|
vrg vrg-name |
Defines the name of the virtual resource group (vRG) to be associated with this vNET. |
vlan-type public|private |
Defines the type of VLAN used in this vNET, which in turn defines the type of vNET (private or public). |
num-vlans 1..4094 |
Defines the number of global VLANs you want to assign to this vNET. Using this parameter allows you to assign a group of VLANs rather than specific VLANs. |
vlans vlan-list |
Defines the VLANs that can be assigned to the public VLAN vNET. You can specify a list or range of VLANs that this vNET can assign to vNET interfaces. Note: Only VLANs within the VLAN range allotted to the vNET admin can be configured. |
public-vlans vlan-list |
Defines the VLAN IDs that can be used to map a Public VLAN to a Private VLAN. This is useful when resources in a vNET have to communicate with a shared resource (such as a shared server, DC GW, firewall, etc.) hosted on the global vNET (default vNET) connected to Shared Ports. You can use the same VLAN ID for both Private vNET and global vNET. |
num-private-vlans 1..4094 |
Defines the number of private VLANs that can be configured in this vNET. You can create up to 4094 VLANs. |
num-bridge-domains 0..4094 |
Defines the number of bridge domains allowed to be created in this vNET. |
vxlans 0..16777215 |
Defines the range of VNIs that can be used by this vNET administrator. The VXLAN ID is a combination of the tenant ID and VLAN ID. Note: Only VXLANs within the VXLAN range allotted to the vNET admin can be configured. |
vxlan-end 0..16777215 |
The last VNI or VXLAN ID assigned to this vNET. |
managed-ports port-list |
The exclusive port(s) associated with this vNET. The vNET administrator can use only the managed ports allotted to the vNET admin while configuring the qualifiers and actions in a vFlow configuration. For vFlow configuration details, see the Configuring and Using vFlows chapter. |
shared-ports port-list |
List of ports that are shared with other vNETs. |
shared-port-vlans vlan-list |
The shared port VLANs associated with this vNET. |
config-admin|no-config-admin |
The config-admin option creates an administrator for the vNET. This is an optional parameter, and the default value is no-config-admin. |
admin user-name |
Add a user name for the admin role. |
create-vnet-mgr|no-create-vnet-mgr |
Choose one of the options to create or not create a dedicated vNET manager. If no-create-vnet-mgr option is selected, then the network/fabric admin manages this vNET. |
vnet-mgr-name vnet-mgr-name-string |
Specify the name of the vNET manager, if you had selected create-vnet-mgr above. If you don’t specify a name, one is automatically configured. |
vnet-mgr-storage-pool storage-pool-name |
Add the storage pool for this vNET. |
Note: You cannot create a vNET inside a vNET.
To delete an existing vNET, use the vnet-delete command:
CLI (network-admin@switch) > vnet-delete name <vnet-name>
To modify the configuration of an existing vNET, use the vnet-modify command.
CLI (network-admin@switch) > vnet-modify
name name-string |
Enter the name of the virtual network (vNET) you want to modify. |
Specify one or more of the following options that needs to be modified: |
|
vlans vlan-list |
The list of VLANs assigned to this vNET. You can specify a list or range of VLANs that the VNET assigns to VNET interfaces. |
managed-ports port-list |
Modify the list of managed (exclusive) ports associated for this vNET. |
num-private-vlans 1..4094 |
Modify the number of private VLANs that the vNET administrator can create for this VNET. You can configure up to 4094 VLANs. |
public-vlans vlan-list |
Modify the public VLANs assigned to this private VLAN vNET. Note: Only VLANs within the VLAN range allotted to the vNET admin can be configured. |
shared-ports port-list |
Modify the shared ports for this vNET. |
vxlans 0..16777215 |
Modify the VXLAN IDs assigned to this vNET. Note: Only VXLANs within the VXLAN range allotted to the vNET admin can be configured. |
vxlan-end 0..16777215 |
Modify the last VXLAN ID assigned to the vNET. |
shared-port-vlans vlan-list |
Modify the vNET shared port VLANs. |
num-bridge-domains 0..4094 |
Modify the number of bridge domains allowed to be created in this private vNET. |
