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.
