This chapter describes contains the following sections:. It enables customers to configure and control access points in a branch or remote office from the corporate office through a wide area network WAN link without deploying a controller in each office. The FlexConnect access points can switch client data traffic locally and perform client authentication locally when their connection to the controller is lost. When they are connected to the controller, they can also send traffic back to the controller.

In the connected mode, the FlexConnect access point can also perform local authentication. Figure shows a typical FlexConnect deployment. Figure FlexConnect Deployment. FlexConnect Authentication Process. Guidelines and Limitations. When an access point boots up, it looks for a controller.

If it finds one, it joins the controller, downloads the latest software image and configuration from the controller, and initializes the radio. It saves the downloaded configuration in nonvolatile memory for use in standalone mode. Note Once the access point is rebooted after downloading the latest controller software, it must be converted to the FlexConnect mode.

A FlexConnect access point can learn the controller IP address in one of these ways:.

Note OTAP is no longer supported on the controllers with 6. When a FlexConnect access point can reach the controller referred to as the connected modethe controller assists in client authentication. When a FlexConnect access point cannot access the controller, the access point enters the standalone mode and authenticates clients by itself.

See the hardware installation guide for your access point for information on LED patterns. When a client associates to a FlexConnect access point, the access point sends all authentication messages to the controller and either switches the client data packets locally locally switched or sends them to the controller centrally switcheddepending on the WLAN configuration.

With respect to client authentication open, shared, EAP, web authentication, and NAC and data packets, the WLAN can be in any one of the following states depending on the configuration and state of controller connectivity:.

In connected mode, the access point provides minimal information about the locally authenticated client to the controller. The following information is not available to the controller:. Local authentication is useful where you cannot maintain a remote office setup of a minimum bandwidth of kbps with the round-trip latency no greater than ms and the maximum transmission unit MTU no smaller than bytes.

In local authentication, the authentication capabilities are present in the access point itself. Local authentication reduces the latency requirements of the branch office. Note When locally switched clients that are connected to a FlexConnect access point renew the IP addresses, on joining back, the client continues to stay in the run state.

These clients are not reauthenticated by the controller. In controller software release 4. However, to support When a FlexConnect access point enters standalone mode, it disassociates all clients that are on centrally switched WLANs. For web-authentication WLANs, existing clients are not disassociated, but the FlexConnect access point stops sending beacons when the number of associated clients reaches zero 0.

It also sends disassociation messages to new clients associating to web-authentication WLANs. Controller-dependent activities, such as network access control NAC and web authentication guest accessare disabled, and the access point does not send any intrusion detection system IDS reports to the controller.

Most radio resource management RRM features such as neighbor discovery; noise, interference, load, and coverage measurements; use of the neighbor list; and rogue containment and detection are disabled.Many Cisco APs can operate in autonomous or lightweight mode; this depends on the image that you run. An AP that serves wireless clients is in local mode. Besides local mode, there are other AP modes. Local mode is the default mode; it offers a BSS on a specific channel.

The AP scans other channels to:. Secondly, when the WAN link is down, your wireless network at the branch site is offline too. FlexConnect is an AP mode for situations like the one above. An AP in sniffer mode dedicates its time to receive The AP becomes a remote wireless sniffer; you can connect to it from your PC with an application like Wildpackets Omnipeek or Wireshark.

Rogue detector mode makes the AP detect rogue devices full-time. The AP becomes a dedicated point-to-point or point-to-multipoint bridge. Two APs in bridge mode can connect two remote sites.

Multiple APs can also form an indoor or outdoor mesh. Explained As Simple As Possible. Full Access to our Lessons. More Lessons Added Every Week! I want the full picture of this so I can visualize the use cases of this rogue detector mode.

There are two things that can be done to contain both the rogue AP and the rogue clients that have connected to them. The first has to do with the rogue clients, while the second has to do with the rogue AP itself. Sniffer mode is used to capture Layer 2 wireless frames and send them to a packet analyzer program such as Wireshark. In this mode, the AP will actively receive frames, and process them, and send them to the configured packet analyzer.

There they can be saved into. SE-Connect mode is different, in that it is used to perform spectrum analysis.An Access Point, as defined by Then along come a way to better scale. For this lightweight architecture, an AP grabs packet out of thin air and then only does real-time stuff to it. It then takes that The controller then converts the Flexconnect changes how packets are processed by allowing the AP to convert the This takes the controller out of the data path, even though the controller is responsible for firmware updates, configurations, RRM, and IPS.

Please keep in mind there are constraints you need to consider before using Flexconnect. See the Restrictions on Flexconnect section of the configuration guide. For example maybe you want all your employee traffic to stay at a branch but you want your guest traffic to go back to the controller for inspection.

The other thing to consider is where These are options in the FlexConnect for how Even though you may select local or central switching, all So what if the controller goes away? Well then your Unless you have local authentication configured. For more information refer to the FlexConnect section of the Configuration Guide. You really make it seem so easy together with your presentation but I find this matter to be really one thing which I believe I might never understand.

It sort of feels too complex and extremely wide for me. I am looking forward in your subsequent publish, I will attempt to get the dangle of it!It enables customers to configure and control access points AP in a branch or remote office from the corporate office through a wide area network WAN link without deploying a controller in each office.

The FlexConnect access points can switch client data traffic locally and perform client authentication locally when their connection to the controller is lost. When they are connected to the controller, they can also send traffic back to the controller.

In the connected mode, the FlexConnect access point can also perform local authentication. The controller software has a more robust fault tolerance methodology to FlexConnect access points. In previous releases, whenever a FlexConnect access point disassociates from a controller, it moves to the standalone mode.

The clients that are centrally switched are disassociated. However, the FlexConnect access point continues to serve locally switched clients.

When the FlexConnect access point rejoins the controller or a standby controllerall clients are disconnected and are authenticated again. This functionality has been enhanced and the connection between the clients and the FlexConnect access points are maintained intact and the clients experience seamless connectivity.

When both the access point and the controller have the same configuration, the connection between the clients and APs is maintained. After the client connection has been established, the controller does not restore the original attributes of the client.

The client username, current rate and supported rates, and listen interval values are reset to the default values only after the session timer expires. There is no deployment restriction on the number of FlexConnect access points per location. Multiple FlexConnect groups can be defined in a single location.

The controller can send multicast packets in the form of unicast or multicast packets to the access point. In FlexConnect mode, the access point can receive multicast packets only in unicast form. VPN and PPTP are supported for locally switched traffic if these security types are accessible locally at the access point.

Workgroup bridges and Universal Workgroup bridges are supported on FlexConnect access points for locally switched clients. FlexConnect supports Client Mobility for a group of up to access points. The reboot, in turn delays the overall deployment of the AP in a branch office. There is no disassociation. When AP is changed from local to FlexConnect it will not reboot, but when it is changed from FlexConnect to local it reboots and displays the following error message, "Warning: Changing AP Mode will reboot the AP and will rejoin the controller afer a few minutes.

Are you sure you want to continue? Changing the AP's mode will also cause the AP to reboot. When an access point boots up, it looks for a controller. If it finds one, it joins the controllerdownloads the latest software image and configuration from the controllerand initializes the radio.

It saves the downloaded configuration in nonvolatile memory for use in standalone mode. A FlexConnect access point can learn the controller IP address in one of these ways:.

How to Configure Flexconnect Mode on Cisco WLC PART 1

If the access point has been assigned a static IP address, it can discover a controller through any of the discovery process methods except DHCP option If the access point cannot discover a controller through Layer 3 broadcast, we recommend DNS resolution.

This method enables you to specify through the access point CLI the controller to which the access point is to connect. When a FlexConnect access point can reach the controller referred to as the connected modethe controller assists in client authentication.I understand that this is due to the heartbeat timer getting expiredand the AP moving into Standalone mode.

But the flexconnect APs take an awfully long timeto shift back to connected modeafter the MPLS failover completes which is usually half a minute max. Is there some tweaking that i am missing here?

Create Please login to create content. Related Content.Moving aside from the normal areas of routing and switching that I usually deal with, this post is about some recent wireless work I did. I quickly realized upon starting to do my configuration that the only mode supported on a vWLC is FlexConnect, so I started looking into this mode.

I started looking at this because my access points would associate fine with the controller but none of my wlans were working.

After research, this turned out to be because my APs were not in FlexConnect mode. Easy enough. There are two main switching modes that this post will cover. Those modes are central and local switching. First you want to set the mode of the access point to FlexConnect as the mode. Then on the wlan, you have options to change between the switching modes: central and local. Those two modes and specifically how they relate to vlan access and dhcp is what I will focus on here.

This option and a few other FlexConnect ones are shown in the image above. Central switching sends the traffic back to the vWLC and pulls the common options such as vlan assignment and more importantly in my case dhcp settings. This allows the access points to work very similar to a standard access point in local mode.

In the case of my test, the clients connected to my access points at my remote locations were all receiving IP addresses tunneled back to the vWLC and the assigned vlan, etc from that wlan. FlexConnect local mode somewhat ignores the vlan and dhcp settings from the vWLC.

My clients were dropped on to the same vlan as the access point running in FlexConnect mode with local switching. For my proof of concept, this would prove especially useful in cases where I wanted clients at a remote location to receive a local IP to that site instead of one tunneled back from the main site through the vWLC. They would look for a dhcp address like any local wired client would at that point. This would allow me to keep management easy utilizing the vWLC, but keep clients segregated at each location.

I remember it by asking in my head: where am I going to get my IP address? Local switching gives me an IP on the local network vlan where my access point is running. Central switching gives me an IP address from my central network, specifically where my vWLC resides and by the options it dictates.

This came in handy for this wireless project I was working on concerning in multiple remote locations, connected by vpn tunnels, all with access points connecting back to a central controller. This info proved valuable to me in this case, so hopefully it can help you as well!

Thanks very much for the short blog!!

Very well explained FlexConnect Local and Central switching. Thanks Kevin. Keep posting this type of technology blogs.Hopefully the answers can be found in this post. FlexConnect is a wireless solution for branch office and remote office deployments. No need for a WLC in each office. A branch user, who is associated to a local switched WLAN, has their traffic forwarded by the on-site router.

Traffic destined off-site to the central site is forwarded as standard IP packets by the branch router.

WL0034 - WLC FlexConnect Fundamental (Part 1)

This diagram below from Enterprise Mobility 7. If that user needs to communicate with computing resources within the branch where that client is associatedtheir data is forwarded as standard IP packets back across the WAN link to the branch location. Depending on the WAN link bandwidth, this might not be desirable behaviour. Thus, if the branch client is connected to a SSID that needs services locally such as print services and internet breakout and centralized services such as e-mail and AD I would suggest to follow local switching.

I would only follow central switching when the only service the WLAN provide is central such as secure guest services for example. For me the main consideration is the WAN-link and here are some of the main considerations to take into account:. Other considerations you might want to look at is roaming capabilities and QOS but from experience with both Cisco and Spectralink wireless phone solutions I had no problems in getting them working over a FlexConnect local switching solution.

A FlexConnect WLAN, depending on its configuration and network connectivity, is classified as being in one of the following defined states.

FlexConnect FlexConnect is a wireless solution for branch office and remote office deployments. The maximum transmission unit MTU must be at least bytes. Connected mode: The WLC is reachable. Standalone mode: The WLC is unreachable. A WAN-link outage between a branch and its central site is a example of such a mode of operation. This state is supported only when FlexConnect is in connected mode. Existing clients are disassociated.

This state is supported only when the FlexConnect AP is in connected mode.

Existing authenticated users continue to be switched locally until session time-out if configured. This state occurs as a result of the AP going into standalone mode.
