Hypervisor Modes

There are two modes for retrieving configuration information from a hypervisor on a
virtual server:
• 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 FTOS configuration.
• Config: VSN retrieves configuration information from a hypervisor and
automatically makes the required configuration changes in FTOS on the switch.

VSN Persistency

VSN installation and configuration is persistent in the FTOS configuration and
remains after a system reload. However, the configuration information retrieved
through a hypervisor is not persistent. If the system reloads, when it boots up the
VSN application will retrieve the network configuration of virtual servers again and
reconfigure FTOS accordingly.

VLAN configuration

Management VLAN

The management interface between a switch and a hypervisor can be a single port or
VLAN interface. If the connection with a hypervisor is through a VLAN, you must
manually configure the VLAN interface on the switch before VSN can establish a
connection with the hypervisor and retrieve information from it about virtual-server
configuration.
A hypervisor's management interface can also be a data interface, which means both
management traffic and data traffic can use the same interface.
Manually configured VLANs are not removed by VSN after application or
configuration changes are made in FTOS on a switch.

Data VLANS

Hypervisor-aware VLANs used for data traffic are automatically configured
according to the configuration parameters retrieved from the hypervisor by VSN as
part of the VLAN trunk on the switch port.
