12.8.2 Switch Without VLANs

When the switch is powered up, the switch uses its default settings to switch frames like an 802.1D
switch. In this default configuration, all ports are a member of the default VLAN (VLAN 1)
including the virtual Host Data Port of the switch, so any port can be used to manage the device as
shown in Figure 12-3.

12.8.3 Switch with VLANs

If the switch is to be configured for multiple VLANs, it may be desirable to configure a
management-only VLAN. This allows a management station connected to the management VLAN
to manage all ports on the switch and make management secure by preventing management via
ports assigned to other VLANs.
NOTE: The switch's virtual Host Data Port, like any other port, has configurable VLAN
membership. For manageability of the device to be maintained, this port must be a
member of the same VLAN as the port to which the management station is connected.
