Pre-requisites for Configuring Access Point Management Interface

Before configuring the AP manager interfaces in the controller you must ensure that you have separate dynamic AP manager interface per port.

Restrictions for Configuring AP Manager Interfaces

  • For IPv4—The MAC address of the management interface and the AP-manager interface is the same as the base LAG MAC address.

  • If only one distribution system port can be used, you should use distribution system port 1.

  • You can configure multiple LAGs in the controller.

Information About AP-Manager Interface

A controller configured with IPv4 has one or more AP-manager interfaces, which are used for all Layer 3 communications between the controller and lightweight access points after the access points have joined the controller.

Note


A controller configured with IPv6 has only one AP-manager and is applicable on management interface. You cannot remove the AP-manager configured on management interface.
The AP-manager IP address is used as the tunnel source for CAPWAP packets from the controller to the access point and as the destination for CAPWAP packets from the access point to the controller.

Note


The controller does not support transmitting the jumbo frames. To avoid having the controller transmit CAPWAP packets to the AP that will necessitate fragmentation and reassembly, reduce MTU/MSS on the client side.

The AP-manager interface communicates through any distribution system port by listening across the Layer 3 network for access point CAPWAP or LWAPP join messages to associate and communicate with as many lightweight access points as possible.

The controller sends the access point a CAPWAP join response allowing the access point to join the controller. When the access point joins the controller, the controller manages its configuration, firmware, control and data transactions.

When an access point performs a reboot or is disconnected from the controller, the join statistics for an access point is maintained from the controller. But this statistics are lost when the controller performs a reboot or disconnects.

A controller configured with IPv6 does not support Dynamic AP-Manager. By default, the management interface acts like an AP-manager interface. Link Aggregation (LAG) is used for IPv6 AP load balancing.

Configuring AP Join in an AP Manager Interface

Before You Begin

The controller sends the access point a CAPWAP join response allowing the access point to join the controller. When the access point joins the controller, the controller manages its configuration, firmware, control and data transactions.

When an access point performs a reboot or is disconnected from the controller, the join statistics for an access point is maintained from the controller. But this statistics are lost when the controller performs a reboot or disconnects.

SUMMARY STEPS

    1.    conf t

    2.    wireless ap-manager interface vlan vlan-ID

    3.    end


DETAILED STEPS
     Command or ActionPurpose
    Step 1conf t
     

    Enters global configuration mode.

     
    Step 2wireless ap-manager interface vlan vlan-ID
     

    Enables the access point to receive the IP address and join the specified VLAN.

    Maps the AP manager to the selected interface.

     
    Step 3end
     

    Returns to EXEC mode.

     

    Viewing Configured Access Point Join Management Interfaces

    Before You Begin

    You can view the access point join interfaces configured in the controller using the following steps:

    SUMMARY STEPS

      1.    show ap summary

      2.    show ap name

      3.    show ap name apname config general

      4.    show wireless interface summary


    DETAILED STEPS
       Command or ActionPurpose
      Step 1show ap summary 

      Displays the summary of all the access points configured in the interface.

       
      Step 2show ap name 

      Displays the summary of all the access points configured in the interface.

       
      Step 3show ap name apname config general 

      Displays all the general parameter configuration for the access point.

       
      Step 4show wireless interface summary 

      Displays all the wireless- management and AP manager interfaces in the controller.
