can roam to different APs that reside in different subnets. The roaming clients stay connected
to your network and do not change IP addresses.
You must use a wireless LAN (WLAN) services module (WLSM) as your wireless domain
services (WDS) device in order to properly configure Layer 3 mobility. Layer 3 mobility is
not supported when you use an AP as your WDS device. For more information on Layer 3
mobility, refer to the Understanding Layer 3 Mobility section of Configuring WDS, Fast
Secure Roaming, and Radio Management.
The command is meant to be used when the AP participates in a WDS infrastructure with a
WLSM module (that acts as the WDS device) where there is Layer 3 mobility. If you use this
command incorrectly, connectivity problems in the WLAN network result, such as these:
Clients do not get IP addresses from the DHCP.♦
In some cases, the clients cannot associate with the AP.♦
Wireless clients cannot associate with the AP.♦
Extensible Authentication Protocol (EAP) authentication does not happen. With the
mobility network−id command configured, the AP tries to build a generic routing
encapsulation (GRE) tunnel for the forwarding of the EAP packets. If no tunnel is
established, the packets cannot go anywhere.
♦
The AP that is configured as a WDS device does not function as expected, and the
WDS configuration does not work.

Q. How many service set identifiers (SSIDs) can you have per VLAN?
A. You can have only one SSID per VLAN. The use of multiple SSIDs over a single VLAN
is not supported with Aironet APs.
Q. What is the BSSID value when multiple ESSIDs are assigned to APs?
A. If the AP is running in lightweight mode, then each ESSID on an AP will be handled via a
different BSSID (where each BSSID is based upon the radio base MAC, and differs only in
the low−order nibble.)
If the AP is running an IOS, then all ESSIDs on the AP will be handled via the same BSSID
(unless MBSSID is configured, in which case they will be handled via different BSSIDs).
Q. Is it possible to set up my A radio for bridge and the G radio for AP
functionality? If yes, how can I do this?
A. Yes, it is possible to set up each radio in your AP for different functionality. In your
scenario, this can be done if you set up different service set identifiers (SSIDs) for the G and
A radio. Then, set up the role in a radio network parameter for the G radio to AP and for the
A radio to root bridge.
Q. When two clients associate to two different APs that are connected on
the same subnet, does the communication happen through the wired
network or happen wirelessly?
A. For this scenario, if the two APs are set to root mode, the communication between the two
APs is through the wired network. If one of the APs is set to repeater mode and the other AP
is set to root mode, the communication between the APs happens wirelessly.
