3.1.2 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.
Figure 3-2 shows an example of a switch configured with port 1 on the
Management VLAN port and the other users belonging to VLANs A, B,
and C.
Figure 3-2 Switch Management with VLANs
To set up the switch shown in Figure 3-2 to establish a management
VLAN on port 1, use the process described below:
1. Use the Device VLAN Configuration screen for the following:
a. Define a new VLAN named “Management VLAN” (or other
suitable name) and its VLAN ID. In this example, the VLAN ID is
set to 2.
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.
