    Can anyone tell me what is wifi 6?

      Wifi 6 is also known as AX WiFi. Wi-Fi 6 is the next generation standard in WiFi technology. Wi-Fi 6 also known as “AX WiFi” or “802.11ax WiFi” builds and improves on the current 802.11ac WiFi standard. Wi-Fi 6 was originally built in response to the growing number of devices in the world.

    Please tell me what are the differences between the AP 2800 and AP 3800?

    • Fakhri

      There are only three main difference between the 3800 & 2800.
      1. 3800 supports mGIG and 2800 doesn’t.
      2. 3800e has SMART ports & 2800 doesn’t.
      3. 3800 is more expensive than the 2800.
      Other than that, both 2800 & 3800 are the same internally and functionality-wise.

    How Does AUTO-Link Aggregation (LAG) work with the AP 2800 and AP 3800?

    • Anonymous

      Both the 2800 and 3800 support LAG across their primary ethernet interfaces and AUX ports. This would provide 2Gbps of uplink to the access point. When operating in LAG, the 3800’s multigigabit port will operate as a single GE port.

      The following Cisco switching series support LAG with the APs:

      – Catalyst 3850 / all models (non–Converged Access mode)
      – Catalyst 3650 / all models (non–Converged Access mode)
      – Catalyst 4500/Sup‐8E
      – Catalyst 6500/Sup 720 or newer

    What is REAP and H-REAP?

    • Brigette
      July 6, 2020 at 07:32

      H-REAP is actually an enhanced version of the Remote Edge Access Point (REAP) feature. With REAP, you had centralized administration of the APs and link resiliency if the WAN link failed, but two fundamental limitations existed.

    1. Click Users > User Authentication.
    2. Choose RADIUS as the authentication method.
    3. Click Configure to configure the RADIUS settings.
    4. In the Settings tab, choose the RADIUS group for authentication and configure the global timeout and retry settings.

    How do I configure the switch to connect with the WLC?

  14. Aaron
    July 22, 2020 at 07:36

    Configure the switch port, to which the WLC is connected, as an IEEE 802.1Q trunk port. Make sure that only the necessary VLANs are allowed on the switch. Usually, the management and the AP-Manager interface of the WLC are left untagged. This means that they assume the native VLAN of the connected switch. This is not necessary. You can assign a separate VLAN to these interfaces. For more information, refer to the Configure the Switch for the WLC section of Wireless LAN Controller and Lightweight Access Point Basic Configuration Example.

    What are the various options available to access the WLC?

    • Eddy
      July 29, 2020 at 09:30

      These are the options:

      GUI access with HTTP or HTTPS
      CLI access with Telnet, SSH, or console access
      Access through service port

    Are there any guidelines for using CAPWAP?

  17. Joselin
    August 20, 2020 at 08:07

    Follow these guidelines when you use CAPWAP:

    If your firewall is currently configured to allow traffic only from access points that use LWAPP, you must change the rules of the firewall to allow traffic from access points that use CAPWAP.

    Make sure that the CAPWAP UDP ports 5246 and 5247 (similar to the LWAPP UDP ports 12222 and 12223) are enabled and are not blocked by an intermediate device that could prevent an access point from joining the controller.

    If access control lists (ACLs) are in the control path between the controller and its access points, you need to open new protocol ports to prevent access points from being stranded.

    The access points use a random UDP source port to reach these destination ports on the controller. In controller software release 5.2, LWAPP was removed and replaced by CAPWAP, but if you have a new out-of-the-box access point, it could try to use LWAPP to contact the controller before it downloads the CAPWAP image from the controller. Once the access point downloads the CAPWAP image from the controller, it uses only CAPWAP to communicate with the controller.

    Note: After 60 seconds of trying to join a controller with CAPWAP, the access point falls back to using LWAPP. If it cannot find a controller using LWAPP within 60 seconds, it tries again to join a controller using CAPWAP. The access point repeats this cycle of switching from CAPWAP to LWAPP and back again every 60 seconds until it joins a controller.

    An access point with the LWAPP recovery image (an access point converted from autonomous mode or an out-of-the-box access point) uses only LWAPP to try to join a controller before it downloads the CAPWAP image from the controller.

    This is the list of options available to access the WLC:

    GUI access with HTTP or HTTPS

    CLI access with Telnet, SSH, or console access

    Access through service port

    For more information on how to enable these modes, refer to the Using the Web-Browser and CLI Interfaces section of the document Cisco Wireless LAN Controller Configuration Guide, Release 5.1. Usually, the management interface IP address is used for GUI and CLI access. Wireless clients can access the WLC only when the optionEnable Controller Management to be accessible from Wireless Clients is checked. In order to enable this option, click the Management menu of the WLC, and click Mgmt via Wireless on the left-hand side. WLC can also be accessed with one of its dynamic interface IP addresses. Use the config network mgmt-via-dynamic-interface command to enable this feature. Wired computers can have only CLI access with the dynamic interface of the WLC. Wireless clients have both CLI and GUI access with the dynamic interface.
