This document provides information on the requirements to configure a
Cisco Wireless LAN (WLAN) Controller for use with the Cisco
Aironet® 600 Series OfficeExtend Access Point
(OEAP). The Cisco Aironet 600 Series OEAP supports split mode operation and it
has facilities that require configuration through the WLAN Controller and
features that can be configured locally by the end user. This document also
provides information about the configurations necessary for proper connection
and supported feature sets.
There are no specific requirements for this document.
The information in this document is based on the Cisco Aironet 600
Series OfficeExtend Access Point (OEAP).
The information in this document was created from the devices in a
specific lab environment. All of the devices used in this document started with
a cleared (default) configuration. If your network is live, make sure that you
understand the potential impact of any command.

The Cisco Aironet 600 Series OEAP is supported on these controllers:
Cisco 5508, WiSM-2 and the Cisco 2504.
The first controller release that supports Cisco Aironet 600 Series
OEAP is 184.108.40.206
The controller’s Management Interfaces need to be on a routable IP
Corporate Firewall configuration needs to be changed to allow traffic
with UDP port numbers 5246 and 5247.
A user is given an access point (AP) primed with the IP address of
the corporate controller, or the user can enter the IP address of the
controller from the configuration screen (setup HTML pages).
The user plugs the AP to their home router.
The AP gets an IP address from their home router, joins the primed
controller and creates a secured tunnel.
Cisco Aironet 600 Series OEAP then advertises the corporate SSID,
which extends the same security methods and services across the WAN to the
If the remote LAN is configured, one wired port on the AP is
tunneled back to the controller.
The user can then enable additionally a local SSID for personal use.
The general configuration on the firewall is to allow CAPWAP control
and CAPWAP management port numbers through the firewall. The Cisco Aironet 600
Series OEAP controller can be placed in the DMZ zone.
Note: The UDP 5246 and 5247 ports need to
be opened on the firewall between the WLAN controller and the Cisco Aironet 600
This diagram shows an Cisco Aironet 600 Series OEAP controller on the
Here is a sample firewall configuration:

access-group Outside in interface outside
In order to transmit the internal AP-Manager IP address to the
OfficeExtend AP as part of the CAPWAPP Discovery Response packet, the
controller administrator needs to make sure that NAT is enabled in the
AP-Manager interface and the correct NATed IP address is sent to the AP.
Note: By default, the WLC will only respond with the NAT IP address during
AP Discovery when NAT is enabled. If APs exist on the inside and outside of the
NAT gateway, issue this command in order to set the WLC to respond with both
the NAT IP address and Non-NAT (inside) Management IP address:
config network ap-discovery nat-ip-only disable
Note: This is only required if the WLC has a NAT IP address.
This diagram shows NAT is enabled, assuming the WLC has a NAT IP
Note: This configuration is not required in the controller provided it is
configured with Internet routable IP address and not behind a firewall.
The Cisco Aironet 600 Series OEAP will connect to the WLC as a Local
Mode Access Point.
Note: Monitor, H-REAP, Sniffer, Rogue Detection, Bridge and SE-Connect
modes are not supported on the 600 Series and are not configurable.
Note: Cisco Aironet 600 Series OEAP functionality in the 1040, 1130, 1140
and 3502i Series Access Points requires configuring the APs for Hybrid REAP
(H-REAP) and setting the sub-mode for the AP to Cisco Aironet 600 Series OEAP.
This is not done with the 600 Series beacuse it uses local mode and cannot be
MAC filtering can be used in the AP authentication during the initial
join process to prevent unauthorized Cisco Aironet 600 Series OEAP units from
joining the controller. This image shows where you enable MAC filtering and
configure AP security policies:
The Ethernet MAC (not the Radio MAC address) is entered here. Also, if
entering the MAC address into a Radius server, lower case must be used. You can
examine the AP Event log for information on how to discover the Ethernet MAC
address (more on this later).
There is one physical remote LAN port (yellow port #4) on the Cisco
Aironet 600 Series OEAP. It is very similar to a WLAN in how it is configured.
However, because it is not wireless and a wired LAN port on the back of the AP,
it is called out and managed as a remote LAN port.
While there is only one physical port on the device, up to four wired
clients can be connected if a hub or switch is used.
Note: The remote LAN client limit supports connecting a switch or hub to
the remote LAN port for multiple devices or connecting directly to a Cisco IP
phone that is connected to that port.
Note: Only the first four devices can connect until one of the devices is
idle for more than one minute. If using 802.1x authentication, there might be
issues attempting to use more than one client on the wired port.
Note: This number does not affect the fifteen limit imposed for the
A remote LAN is configured similarly to a WLAN and guest LAN configured
on the controller.
WLANs are wireless security profiles. These are the profiles that are
used by your corporate network. The Cisco Aironet 600 Series OEAP supports at
most two WLANs and one remote LAN.
A remote LAN is similar to a WLAN except it is mapped to the wired port
on the back of the access point (port #4 in yellow) as shown in this
Note: If you have more than two WLANs or more than one remote LAN, all need
to be placed into an AP Group.
This image shows where WLANs and the remote LAN are
This image shows a sample OEAP group name:
This image shows a WLAN SSID and RLAN
If the Cisco Aironet 600 Series OEAP is entered into an AP group, the
same limits of two WLANs and one remote LAN apply for the configuration of the
AP group. Also, if the Cisco Aironet 600 Series OEAP is in the default group,
which means it is not in a defined AP Group, the WLAN/remote LAN IDs need to be
set at less than ID 8 because this product does not support the higher ID sets.
Keep ID sets to less than 8 as shown in this
Note: If additional WLANs or remote LANs are created with the intent of
changing the WLANs or remote LAN being used by the Cisco Aironet 600 Series
OEAP, then disable the current WLANs or remote LAN that you are removing before
enabling the new WLANs or remote LAN on the 600 Series. If there is more than
one remote LAN enabled for an AP group, disable all remote LANs and then enable
If there are more than two WLANs enabled for an AP group, disable all
WLANs and then enable only two.
When setting the security setting in the WLAN, there are specific
elements that are not supported on the 600 series.
For Layer 2 Security, only these options are supported for the Cisco
Aironet 600 Series OEAP:
Note: Only 802.1x or PSK should be selected.
Security encryption settings need to be identical for WPA and WPA2 for
TKIP and AES as shown in this image:
These images provide examples of incompatible settings for TKIP and
Note: Be aware that security settings permit unsupported features.
These images provide examples of compatible settings:
Security settings can be left open, set for MAC filtering, or set for
Web Authentication. The default is to utilize MAC filtering.
This image shows Layer 2 and Layer 3 MAC filtering:
QoS settings are managed:
Advanced settings should also be managed:
Coverage Hole Detection should not be enabled.
Aironet IE (Information Elements) should not be enabled as they are
Management Frame Protection (MFP) is also not supported, and should
be disabled or configured as optional as shown in this image:
Client Load Balancing and Client Band Select are not supported and
should not be enabled:
Only fifteen users are allowed to connect on the WLAN Controller WLANs
provided on the 600 series at any one time. A sixteenth user cannot
authenticate until one of the first clients de-authenticates or a timeout
occurred on the controller.
Note: This number is cumulative across the controller WLANs on the 600
For example, if two controller WLANs are configured and there are
fifteen users on one of the WLANs, no users will be able to join the other WLAN
on the 600 series at that time. This limit does not apply to the local private
WLANs that the end user configures on the 600 series designed for personal use
and clients connected on these private WLANs or on the wired ports do not
affect these limits.
The radios for the 600 series are controlled through the Local GUI on
the 600 series and not through the Wireless LAN Controller.
Attempting to control the spectrum channel, power, or disable the
radios through the controller will fail to have any effect on the 600 series.
The 600 series will scan and choose channels for 2.4 GHz and 5.0 GHz
during startup as long as the default settings on the Local GUI are left as
default in both spectrums.
Note: If the user disables one or both radios locally (that radio is also
disabled for corporate access), also as previously stated, RRM and advanced
features such as monitor, H-REAP, sniffer are beyond the capabilities of the
Cisco Aironet 600 Series OEAP which is positioned for home and teleworker
The channel selection and bandwidth for 5.0 GHz are configured here on
the local GUI of the Cisco Aironet 600 Series OEAP.
20 and 40 MHz wide settings are available for 5
2.4 GHz 40 MHz wide is not supported and fixed at 20
40 MHz wide (channel bonding) is not supported in 2.4
The Cisco Aironet 600 Series OEAP is designed for single AP
deployments. Therefore, client roaming between the 600 series is not supported.
Note: Disabling the 802.11a/n or 802.11b/g/n on the controller might not
disable these spectrums on the Cisco Aironet 600 Series OEAP because local SSID
might still be working.
The end user has enable/disable control over the radios inside the
Cisco Aironet 600 Series OEAP.
802.1x Support on the Wired Port
In this initial release, 802.1x is only supported on Command Line
Note: GUI support has not been added yet.
This is the wired port (port #4 in yellow) on the back of the Cisco
Aironet 600 Series OEAP and is tied to the remote LAN (see previous section on
configuring remote LAN).
At any time, you can use the show command to
display the current remote LAN configuration:
show remote-lan <remote-lan-id>
In order to change the remote LAN configuration, you must first disable
remote-lan disable <remote-lan-id>
Enable 802.1X authentication for the remote LAN:
config remote-lan security 802.1X enable <remote-lan-id>
You can undo it by using this command:
config remote-lan security 802.1X disable <remote-lan-id>
For the remote LAN, “Encryption” is always “None” (as displayed in
show remote-lan) and not configurable.
If you want to use local EAP (in the controller) as authentication
config remote-lan local-auth enable <profile-name> <remote-lan-id>
Where the profile is defined either
through the controller GUI (Security > Local EAP) or CLI
(config local-auth ). Refer to the controller guide
for details on this command.
You can undo it bywith this command:
config remote-lan local-auth disable <remote-lan-id>
Or, if you use an external AAA authentication server:
Where server is configured through the
controller GUI (Security > RADIUS > Authentication) or CLI
(config radius auth). Refer to the controller guide
for more information about this command..
After you are done with the configuration, enable the remote
config remote-lan enable <remote-lan-id>
Use the show remote-lan
<remote-lan-id> command in order to
verify your setting.
For the remote LAN client, you need to enable 802.1X authentication and
configure correspondingly. Refer to your device user guide.
This image shows the wiring diagram for the Cisco Aironet 600 Series
The default DHCP scope of the Cisco Aironet 600 Series OEAP is 10.0.0.x
so you can browse to the AP on ports 1-3 using the address of 10.0.0.1. The
default username and password are admin.
Note: This is different from the AP1040, 1130, 1140 and 3502i which used
Cisco as the username and password.
If the radios are up and a personal SSID has already been configured,
you can access the configuration screen wirelessly. Otherwise, you need to use
local Ethernet ports 1-3.
In order to login, the default username and password are
Note: The yellow port #4 is not active for local use. If a remote LAN is
configured on the controller, this port tunnels back after the AP successfully
joins the controller. In order to browse to the device, locally use ports 1-3:
Once you successfully browse to the device, you see the home status
screen. This screen provides radio and MAC statistics. If radios have not been
configured, the configuration screen permits the user to enable the radios, set
channels and modes, configure local SSIDs, and enable the WLAN
From the SSID screen is where the user can configure the personal WLAN
network. The corporate radio SSID and security parameters are set up and pushed
down from the controller (after you configure the WAN with the IP of the
controller), and a successful join has occurred.
This image shows an SSID local MAC filtering
After the user configures the personal SSID, the screen below permits
the user to set up security on the private home SSID, enable radios, and
configure MAC filtering if desired. If the personal network is using 802.11n
rates, it is recommended that the user choose an authentication type,
encryption type and a passphrase enabling WPA2-PSK and AES.
Note: These SSID settings are different from the corporate settings if the
user chooses to disable one or both of the radios (both are alsodisabled for
corporate use as well).
Users who have access locally to the admin control settings have
control over core functions such as radio enable/disable unless the device is
password protected and configured by the administrator. Therefore, care must be
taken not to disable both radios as this can result in a loss of connectivity
even if the device successfully joins the controller.
This image shows the system security
It is expected that the home teleworker installs the Cisco Aironet 600
Series OEAP behind a home router as this product is not designed to replace the
functionality of a home router. This is because the current version of this
product does not have firewall support, PPPoE support or port forwarding. These
are features customers expect to find in a home router.
While this product can work without a home router, it is recommended
not to position it that way for the reasons stated. Also, there can be
compatibility issues connecting directly to some modems.
Given that most home routers have a DHCP scope in the 192.168.x.x
range, this device has a default DHCP scope of 10.0.0.x and is configurable.
If the home router happens to be using 10.0.0.x, then you must
configure the Cisco Aironet 600 Series OEAP to use a 192.168.1.x or compatible
IP address to avoid network conflicts.
This image shows a DHCP scope
Caution: If the Cisco Aironet 600 Series OEAP is not staged or configured by
the IT administrator, the user needs to enter the IP address of the corporate
controller (see below) so the AP can successfully join the controller. After a
successful join, the AP should download the latest image from the controller
and the configuration parameters such as the corporate WLAN settings. Also, if
configured, the remote LAN settings wired port #4 on the back of the Cisco
Aironet 600 Series OEAP.
If it does not join, verify that the IP address of the controller is
reachable via the Internet. If MAC filtering is enabled, verify that the MAC
address is successfully entered into the controller.

This image shows the physical aspects of the Cisco Aironet 600 Series
This AP is designed to be mounted on a table and has rubber feet. It
can also be wall mounted, or can sit upright using the supplied cradle. Try to
locate the AP as close to the intended users as possible. Avoid areas with
large metal surfaces, such as sitting the device on a metal desk or near a
large mirror. The more walls and objects between the AP and the user result in
lower signal strength, and can reduce performance.
Note: This AP utilizes a +12 Volt power supply and does not utilize Power
over Ethernet (PoE). Also, the device does not supply PoE. Make sure the right
power adapter is used with the AP. Also, make sure not to use other adapters
from other devices such as laptops and IP phones as these can damage the AP.
The unit can be mounted on the wall with plastic anchors or wood
The unit can be mounted upright using the supplied
The Cisco Aironet 600 Series OEAP has antennas located on the edges of
the AP. The user should take care not to place the AP in areas near metal
objects or obstructions which can cause the signal to become directional or
diminished. The antenna gain is approximately 2 dBi in both bands and designed
to radiate in a 360 degree pattern. Similar to a light bulb (without a lamp
shade), the goal is to radiate in all directions. Think of the AP as you would
a lamp and try to place it in close proximity to the users.
Metal objects, such as mirrors, obstruct the signal much like the
lampshade analogy. You can experience degraded throughput or range if the
signal must penetrate or go through solid objects. If you expect connectivity,
for example in a three story home, avoid placing the AP in the basement and try
to mount the AP in a central location within the home.
The access point has six antennas (three per

Verify that the initial wiring is correct. This confirms that the WAN
port on the Cisco Aironet 600 Series OEAP is connected to the router and can
receive an IP address successfully. If the AP does not appear to join the
controller, connect a PC to port 1-3 (home client ports) and see if you can
browse to the AP using the default IP address of 10.0.0.1. The default username
and password is admin.
Verify that the IP address for the corporate controller is set. If not,
enter the IP address and reboot the Cisco Aironet 600 Series OEAP so it can try
to establish a link to the controller.
Note: The corporate port #4 (in yellow) cannot be used to browse to the
device for configuration purposes. This is essentially a “dead port” unless a
remote LAN is configured. Then, it will tunnel back to corporate (used for
wired enterprise connectivity)

is recommended that you check these items:
Verify that the router is functional and connected to the WAN Port

If the join process fails, the LED cycles though colors or perhaps
flashes orange. If this occurs, check the event log for further details. In
order to get to the event log, browse to the AP (using personal SSID or wired
ports 1-3) and capture this data for the IT administrator to review.
This image shows the Cisco Aironet 600 Series OEAP event
If the join process fails and this is the first time the Cisco Aironet
600 Series OEAP has tried to connect to the controller, check the AP join
statistics for the Cisco Aironet 600 Series OEAP. In order to do this, you need
the Base Radio MAC of the AP. This can be found in the event log. Here is an
example of an event log with comments to help you interpret this:
Once this is known, you can look in the controller monitor statistics
to determine whether the Cisco Aironet 600 Series OEAP has joined the
controller or has ever joined the controller. Also, this should provide an
indication on why, or if, a failure has occurred.
If AP authentication is required, verify the Cisco Aironet 600 Series
OEAP Ethernet MAC address (not the radio MAC address) has been entered into the
Radius server in lower case. You can determine the Ethernet MAC address from
the event log as well.
Searching on the Controller for the Cisco Aironet 600 Series
If you have determined that Internet is accessible from a PC connected
to the local Ethernet port, but the AP still cannot join the controller, and
you have confirmed the controller IP address is configured in the local AP GUI
and is reachable, then confirm if the AP has ever joined successfully. Perhaps
the AP is not in the AAA server. Or, if DTLS handshaking fails, the AP might
have a bad certificate or date/time error on the controller.
If no Cisco Aironet 600 Series OEAP units can join the controller,
verify that the controller is on the DMZ is reachable and has UDP ports 5246
and 5247 open.
The AP joins the controller properly, but the wireless client cannot
associate with the Corporate SSID. Check the event log to see if an association
message reaches the AP.
The next figure shows the normal events for client association with
corporate SSID with WPA or WPA2. For SSID with open authentication or static
WEP, there is only one ADD MOBILE event.
Event Log – Client Association
If (Re)Assoc-Req event is not in the log, verify the client has the
right security settings.
If (Re)Assoc-Req event shows up in the log but the client cannot
associate properly, enable the debug client <MAC
address> command on the controller for the client and
investigate the problem in the same way as a client working with other Cisco
non-OEAP access points.
The following event logs with comments can assist you in
troubleshooting other Cisco Aironet 600 Series OEAP connection issues.
Here are a few samples collected from the Cisco Aironet 600 Series OEAP
event log files with comments to help with interpreting the event
The event log example in this section can occur when the Internet
connection fails or ends up being very slow or intermittent. This can be caused
by your ISP network, the ISP modem, or your home router. Sometimes connectivity
from the ISP drops or becomes unreliable. When this occurs, the CAPWAP link
(tunnel back to corporate) can fail or have difficulty.
Here is an example of such a failure in the event
When using the Cisco Aironet 600 Series OEAP in a hotel or other pay
for use venue, before the Cisco Aironet 600 Series OEAP can tunnel back to the
controller, you need to get through the walled garden. In order to do this,
plug a laptop into one of the wired local ports (port 1-3) or use a personal
SSID to login to the hotel and satisfy the splash screen.
Once you have Internet connectivity from the home side of the AP, the
unit establishes a DTLS tunnel and your corporate SSIDs. Then, wired port #4
(assuming a remote LAN is configured) becomes active.
Note: This might take a few minutes, watch the Cisco logo LED for solid
blue or purple to indicate successful join. At this point both personal and
corporate connectivity are active.
Note: The tunnel breaks when hotel or another ISP disconnects (usually 24
hours). Then, you have to start same process over. This is by design and is

When you upload the configuration file from a controller to a TFTP/FTP
server, Remote-LAN configurations are uploaded as WLAN configurations. Refer to
Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for
Release 220.127.116.11 for more information.
On the OEAP-600, if the CAPWAP connection fails due to an
authentication failure on the controller, the Cisco logo LED on the OEAP-600
can turn off for some time before the OEAP-600 tries to restart the CAPWAP
attempt. This is normal so you should be aware that the AP did not die should
the logo LED momentarily turns off.

Support for Dual RLAN port feature (CLI only)
This note applies to OEAP-600 series APs using the Dual RLAN Ports
feature, which allows OEAP-600 Ethernet port 3 to operate as a remote LAN. The
configuration is only allowed through the CLI, and here is an example:
Config network oeap-600 dual-rlan-ports enable|disable
In the event that this feature is not configured, the single port 4
remote-lan continues to function. Each port uses a unique remote-lan for each
port. The remote-lan mapping is different, which depends on whether the
default-group or AP Groups is used.
If the default-group is used, a single remote LAN with an even
remote-lan ID is mapped to port 4. For instance, the remote-lan with
remote-lan-id 2 is mapped to port 4 (on the OEAP-600). The remote-lan with an
odd numbered remote-lan ID is mapped to port 3 (on the OEAP-600).
As an example, take these two remote-lans:
(Cisco Controller) >show remote-lan summary
Number of Remote LANS............................ 2
RLAN ID RLAN Profile Name Status Interface Name
------- ------------------------------------- -------- --------------------
2 rlan2 Enabled management
3 rlan3 Enabled management
rlan2 has an even numbered remote-lan ID, 2, and as such maps to port
4. rlan3 has odd remote-lan ID 3, and so maps to port 3.
If you use an AP group, the mapping to the OEAP-600 ports is determined
by the AP-Group ordering. In order to use an AP group, you must first delete
all remote-lans and WLANs from the AP-group and leave it empty. Then add the
two remote-lans to the AP group. First add the port 3 AP remote-LAN first, then
add port 4 remote group, and finally add any WLANs.
A remote-lan in the first position in the list maps to port 3, and
second in the list maps to port 4, as in this example:
RLAN ID RLAN Profile Name Status Interface Name
------- ------------------------------------- -------- --------------------
2 rlan2 Enabled management
3 rlan3 Enabled management
