Figure 2. Virtual Server Networking Example

For any change, VSN subscribes use hypervisor to notify the switch. Depending on the hypervisor mode

you configure, the Dell Networking OS may automatically update its configuration, provide provisioning

for configuration changes, or require system administrator intervention.

Hypervisor Modes

There are two modes for retrieving configuration information from a hypervisor on a virtual server: check

and config.

• Check — VSN retrieves configuration information from a hypervisor and notifies the system

administrator when there is a change in the network configuration; for example, when a VLAN is

added or removed. A system administrator must make manual updates to the Dell Networking OS

configuration.

• Config — VSN retrieves configuration information from a hypervisor and automatically makes the

required configuration changes in the Dell Networking OS on the switch.

VSN Persistency

VSN installation and configuration are persistent in the Dell Networking OS configuration and remains

after a system reload.

However, the configuration information a hypervisor retrieves is not persistent. If the system reloads,

when it boots up, the VSN application retrieves the network configuration of virtual servers again and

reconfigures the Dell Networking OS accordingly.
