packets that are sent from the wireless controller do not carry the 802.1Q header, and all
untagged packets that are sent to the wireless controller are treated as management VLAN
traffic.
Note: Use a tagged VLAN or change the tagged VLAN ID only if the hubs
and switches on your LAN support 802.1Q. If they do not, and you did
not configure a tagged VLAN with the same VLAN ID on the hubs and
switches in your network, IP connectivity might be lost.
The management VLAN must provide IP connectivity between the wireless controller and the
access points. If the wireless controller and the access points are on different management
VLANs, external VLAN routing must allow IP connectivity between the wireless controller and
the access points.
For information about how to configure management VLANs, see
Link Aggregation Settings
Client VLANs
Each authenticated WiFi user is placed into a VLAN that determines the user's DHCP server,
IP address, and Layer 2 connection. Although you could place all authenticated WiFi users
into the single VLAN that is specified in the basic security profile, the wireless controller
allows you to group WiFi users into separate VLANs based on the WiFi SSID to differentiate
access to network resources. For example, you might place authorized employee users into
one VLAN, and itinerant users, such as contractors or guests, into a separate VLAN. To use
different VLANs, you must create different security profiles.
For information about how to configure regular VLANs, see
Aggregation Settings on page 102.
DHCP Server
The wireless controller can function as a DHCP server and assign IP addresses to both WiFi
and wired devices that are connected to it. You can add up to 64 DHCP server pools, each
assigned to a different VLAN.
Specifying an internal DHCP server on the wireless controller automatically enables DHCP
option 43 (vendor-specific information) with the IP address of the wireless controller. Whether
you must enable option 43 on an external DHCP server in a Layer 2 network depends on the
firmware version that the wireless controller is running:
• Firmware version 4.x and earlier versions. Option 43 must be enabled on an external
DHCP server in a Layer 2 network.
• Firmware version 5.x and later versions. Option 43 is not required on an external
DHCP server in a Layer 2 network.
For discovery across Layer 3 networks, you always must enable option 43 on an external
DHCP server.
