Independent WLANs Only
An independent WLAN configuration forces all MU traffic be bridged locally by the AAP. No wireless
traffic is tunneled back to the switch. Each extended WLAN is mapped to the access point's LAN1
interface. The only traffic between the switch and the AAP are control messages (for example,
heartbeats, statistics and configuration updates).
Extended WLANs with Independent WLANs
An AAP can have both extended WLANs and independent WLANs operating in conjunction. When
used together, MU traffic from extended WLANs go back to the switch and traffic from independent
WLANs is bridged locally by the AP.
All local WLANs are mapped to LAN1, and all extended WLANs are mapped to LAN2.
Extended WLAN with Mesh Networking
Mesh networking is an extension of the existing wired network. There is no special configuration
required, with the exceptions of setting the mesh and using it within one of the two extended VLAN
configurations and defining an access point radio as a preferred base bridge.
NOTE
The mesh backhaul WLAN must be an independent WLAN mapped to LAN1. The switch enforces the
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.
How the AP Receives its Adaptive Configuration
An AAP does not require a separate "local" or "running" configuration. Once enabled as an AAP, the
AP obtains its configuration from the switch. If the AP’s WAN link fails, it continues to operate using
the last valid configuration until its link is re-established and a new configuration is pushed down
from the switch. There is no separate file-based configuration stored on the switch.
Only WLAN, VLAN extension and radio configuration items are defined for the AAP by its connected
switch. None of the other access point configuration items (RADIUS, DHCP, NAT, Firewall etc.) are
configurable from the connected switch.
After the AP downloads a configuration file from the switch, it obtains the version number of the
image it should be running. The switch does not have the capacity to hold the access point’s
firmware image and configuration. The access point image must be downloaded using a means
outside the switch. If there is still an image version mismatch between what the switch expects and
what the AAP is running, the switch will deny adoption.
Adaptive AP Pre-requisites
Converting an access point into an AAP requires:
• A version 2.0 or higher firmware running on the access point.
• A RFS4000, RFS6000 or RFS7000 (running firmware version 1.1 or later) model switch.
• The appropriate switch licenses providing AAP functionality on the switch.
• The correct password to authenticate and connect the adaptive to the switch.
