If you want to configure the Guest and Internal networks on Virtual LAN (VLANs), the switch and
DHCP server you are using must support VLANs.
As a prerequisite step, configure a port on the switch for handling VLAN tagged packets as described
in the IEEE 802.1Q standard.
Guest Welcome Screen settings are shared among access points across the cluster. When you
update these settings for one access point, the configuration will be shared with the other access
points in the cluster. For more information about which settings are shared by the cluster and which
are not, see "Which Settings are Shared as Part of the Cluster Configuration and Which Are Not?" on
page 45.
To configure Internal and Guest networks on virtual LANs, do the following:
1. Use an Ethernet cable to make a wired connection from the LAN port on the access point to the LAN.
(Make sure this port is configured to handle VLAN tagged packets.)
2. Configure Ethernet (Wired) Settings
(Wired) Settings" on page 89.
(Start by enabling Guest Access and choosing
described in "Specifying a Virtual Guest Network" on page 92.)
3. Provide the radio interface settings and network names (SSIDs) for both Internal and Guest networks
as described in "Wireless Settings" on page 97.
The figure below shows an example of a Guest network implemented via VLAN; the dotted red lines
indicate dedicated guest connections.
