Bridged APs in a VLAN
In order to map an ESSID to a VLAN, the VLAN must first be configured. To create a
VLAN from the CLI, use the command vlan name tag id. The name can be up to 16
alphanumeric characters long and the tag id between 1 and 4,094.
For example, to create a VLAN named guest with a tag number of 1, enter the
following in global configuration mode:
controller (config)# vlan guest tag 1
controller (config-vlan)#
As shown by the change in the prompt above, you have entered VLAN configuration
mode, where you can assign the VLAN interface IP address, default gateway, DHCP
Pass-through or optional DHCP server (if specified, this DHCP server overrides the
controller DHCP server configuration).
In the following example, the following parameters are set:
 VLAN interface IP address: 10.1.1.2 with a subnet mask of 255.255.255.0
 Default gateway: 10.1.1.1
 DHCP server: 10.1.1.254
controller (config-vlan)# ip address 10.1.1.2 255.255.255.0
controller (config-vlan)# ip default-gateway 10.1.1.1
controller (config-vlan)# ip dhcp-server 10.1.1.254
controller (config-vlan)# exit
controller (config)#
To create a VLAN from the GUI, click Config > Wired > VLAN > Add.
Bridged APs in a VLAN
When creating an ESS, AP300/AP400 and AP1000 can be configured to bridge the traffic to
the Ethernet interface. This is called
bridged VLAN dataplane mode (per ESSID); it is also
sometimes known as Remote AP mode. These two AP models also have the capability to
tag the Ethernet frames when egressing the port, using 802.1Q VLAN tags, and setting the
802.1p priority bit. Bridging is configured setting the Dataplane Mode parameter in the ESS
profile to Bridged (default is Tunneled).
In Tunneled mode, all traffic in an ESS is sent from the AP to the controller, and then
forwarded from there. This is configured on a per ESS profile basis. In Bridged mode, client
traffic is sent out to the local switch. Meru control and coordination traffic is still sent
between the AP and the controller.
Remote AP300/AP400s can use VLANs with System Director 4.0 and later. When
configuring an ESS, the Dataplane Mode setting selects the type of AP/Controller
configuration:
