4.3 VLAN
This section discusses how to configure the NAP’s VLAN settings. The management VLAN assigned to the
NAP should allow it to connect to the Internet through your network.
Note: Misconfiguring the management VLAN settings in your NAP can make it inaccessible. If
this happens, you will have to reset the NAP.
Figure 19 Management VLAN Setup
For example, to access and manage the NAP from a computer (A), the NAP and the switch B’s ports to
which computer A and the NAP are connected should be in the same VLAN, as shown in the figure
above.
Note: Make sure your VLAN settings allow the NAP to connect to the Internet.
A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical
networks. Devices on a logical network belong to one group. A device can belong to more than one
group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same
group(s); the traffic must first go through a router.
VLAN also increases network performance by limiting broadcasts to a smaller and more manageable
logical broadcast domain. In traditional switched environments, all broadcast packets go to each and
every individual port. With VLAN, all broadcasts are confined to a specific broadcast domain.
