VLAN Configurations
The following sections describe management, data, and hypervisor-unaware VLANs.
Management VLANs
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, manually configure the VLAN interface on the
switch before VSN can establish a connection with the hypervisor and retrieve information from it about
the 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.
VSN does not remove manually configured VLANs after application or configuration changes are made in
the Dell Networking OS.
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.
To display the VSN hypervisor-learned VLANs on the switch, use the show vlan command. As shown in
the following example, VSN VLANs that are automatically configured, display with a G tag in the left-most
column and are associated with ports marked with an H tag. If you have manually configured a VSN VLAN
on the switch, the VLAN has no tag; the associated ports display with an H tag.

Hypervisor-Unaware VLANs
VSN cannot discover VLAN configurations from a hypervisor.
If an application requires a hypervisor-unaware VLAN, you must configure the VLAN manually. When VSN
retrieves and updates a network configuration, user-configured VLANs are not removed.
