Today I am going to talk about the Cisco Wireless Flex-connect mode and how it works in the enterprise or campus network with wireless connect with APs. There are two different modes, one is the local switched mode and another is called as Flex-connect mode. In the case of the local switched
mode, an AP creates two CAPWAP tunnels to the WLC. One is for management, the other is data traffic. This behaviour is known as "centrally switched" because the data traffic is switched(bridged) from the AP to the controller where it is then routed by some routing device. Office 1 is located in New Delhi (using local mode) Office 2 is located in Sydney(using flex connect) Datacenter is located in San Jose Local Mode means that a tunnel is created from Wireless AP to the WLC. All traffic goes to the WLC. Authentication and user traffic. If office 1(New Delhi) is configured with local mode, the wireless clients will actually have all of their traffic tunnelled to San Jose and will use an IP from the WLC to get to other locations on the network. Internet browsing for the users will be from San Jose. If New Delhi wants to get a resource from Sydney the client will tunnel to San Jose and then go over company network to Sydney and back. In FlexConnect. Only authentication traffic is sent to WLC. The AP will hand out local VLANS from the Sydney office. It will use DHCP from Sydney office. So once authentication takes place all traffic takes place locally. Internet browsing would go out Sydney connection. traffic from Sydney user to San Jose resource would follow same path as a wired user. Flex-Connect Mode
There are still a couple of key features that FlexConnect does not support. FlexConnect groups can only contain up to group of 25 APs (unless you are using a 7500, 8500, or vWLC). That group determines the APs between which a client can do fast-roaming. Converting multicast to layer 2 unicast over the air (VideoStream) is not supported, and thus all multicast streaming video will be sent at the highest mandatory rate and not the highest rate that the client supports. There are some other issues for many of customers is that the SSID to VLAN mapping is done on an AP by AP basis. This is an issue for two reasons. You have to touch each AP to manually do this, or you can use a lightweight AP template in Prime/NCS/WCS. If you don't have Prime/NCS/WCS, then that can be a headache. The second is that there are times, particularly when upgrading code, that the APs will "forget" their mappings and revert to the default. And, you don't necessarily know that until your end users are calling to complain that they can't connect to the network. I'm going to check on how that is working with current code on my next upgrade. Flex-Connect Modes There are two modes in Flex-connect deployments and these modes are
Supported Hardware FlexConnect is only supported on these components:
What is a difference between local AP mode and FlexConnect AP mod?Local mode tunnels traffic to the wlc and traffic has to egress from the controller. FlexConnect with local switching places traffic on the switchport the ap is connected to.
What is AP mode FlexConnect?FlexConnect AP mode enables switching traffic between an SSID and a VLAN locally if the CAPWAP to the WLC is down, even when the AP is at a remote site. It can also be configured to egress at the access point's LAN port.
What are the different modes of access point and explain?Access Point mode is used to connect to wireless clients(wireless adapter cards) such as laptops, desktops, and PDAs. Wireless clients can only communicate to AP's in Access Pointmode. AP Client or Wireless Client mode allows the Access Point tobecome a wireless client to another AP.
What is the use of FlexConnect?FlexConnect is a wireless solution for branch office and remote office deployments. From a central Wireless LAN Controller (WLC), hopefully in your Data Centre with a redundant WLC not too far away, you can configure, control and manage access points in a branch or remote office. No need for a WLC in each office.
