Summit WM3000 Series Controller System Reference Guide 487
Extended WLANs Only
An extended WLAN configuration forces all MU traffic through the controller (tunneled traffic). No
wireless traffic is locally bridged at the AP.
Each extended WLAN is mapped to the access point's virtual LAN2 subnet. By default, the access
point's LAN2 is not enabled and the default configuration is set to static with IP addresses defined as all
zeros. If the extended VLAN option is configured on the controller, the following configuration updates
are made automatically:
● The AP’s LAN2 subnet becomes enabled
● All extended VLANs are mapped to LAN2.
MUs on the same WLAN associated to the AP can communicate locally at the AP Level without going through the
controller. If this scenario is undesirable, the access point's MU-to-MU disallow option should be enabled.
Independent WLANs Only
An independent WLAN configuration forces all MU traffic be bridged locally by the AP. No wireless
traffic is tunneled back to the controller. Each independent WLAN is mapped to the access point's
LAN1 interface. The only traffic between the controller and the AP are control messages (for example,
heartbeats, statistics and configuration updates).
Extended WLANs with Independent WLANs
An AP can have both extended WLANs and independent WLANs operating in conjunction. When used
together, MU traffic from extended WLANs go back to the controller and traffic from independent
WLANs is bridged locally by the AP.
All independent WLANs are mapped to LAN1, and all extended WLANs are mapped to LAN2.
Extended VLAN on Mesh Networking
Mesh networking is an extension of the existing wired network. There is no special configuration
required, with the exception of setting the mesh and using it within one of the two extended VLAN
configurations.
The mesh backhaul WLAN must be an independent WLAN mapped to LAN2. The controller enforces the mesh
WLAN be defined as an independent WLAN by automatically setting the WLAN to independent when backhaul is
selected. The AP ensures the backhaul WLAN be put on LAN1.
