Configuring Management Interfaces

Finding Feature Information

Your software release may not support all the features documented in this module. For the latest feature information and caveats, see the release notes for your platform and software release. Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to http:/​/​www.cisco.com/​go/​cfn. An account on Cisco.com is not required.

Information About the Management Interface

The management interface is the default interface for in-band management of the controller and connectivity to enterprise services such as AAA servers. It is also used for communications between the controller and access points. The management interface has the only consistently “pingable” in-band interface IP address on the controller. You can access the GUI of the controller by entering the management interface IP address of the controller in the address field of either Internet Explorer or Mozilla Firefox browser.

For CAPWAP, the controller requires one management interface to control all inter-controller communications and one AP-manager interface to control all controller-to-access point communications, regardless of the number of ports.

If the service port is in use, the management interface must be on a different supernet from the service-port interface.


Note


To prevent or block a wired or wireless client from accessing the management network on a controller (from the wireless client dynamic interface or VLAN), the network administrator must ensure that only authorized clients gain access to the management network through proper CPU ACLs, or use a firewall between the client dynamic interface and the management network.


Do not map a guest WLAN to the management interface. If the EoIP tunnel breaks, the client could obtain an IP and be placed on the management subnet.

Do not configure wired clients in the same VLAN or subnet of the service port of the controller on the network. If you configure wired clients on the same subnet or VLAN as the service port, it is not possible to access the management interface of the controller.

Pre-requisites for Configuring Management Interfaces

The pre-requisites for configuring the management interfaces on the controller follow:

  • For Cisco 5700 Series Controllers in a non-link-aggregation (non-LAG) configuration, the management interface must be on a different VLAN than any dynamic AP-manager interface. Otherwise, the management interface cannot fail over to the port that the AP-manager is on.
  • If the service port is in use, the management interface must be on a different supernet from the service-port interface.
  • To prevent or block a wired or wireless client from accessing the management network on a controller (from the wireless client dynamic interface or VLAN), the network administrator must ensure that only authorized clients gain access to the management network through proper CPU ACLs, or use a firewall between the client dynamic interface and the management network.

Restrictions for Configuring Management Interfaces

The following are the restrictions for configuring the controller's management interface:

  • Do not map a guest WLAN to the management interface. If the EoIP tunnel breaks, the client could obtain an IP and be placed on the management subnet.
  • Do not configure wired clients in the same VLAN or subnet of the service port of the controller on the network. If you configure wired clients on the same subnet or VLAN as the service port, it is not possible to access the management interface of the controller.

Configuring the Management Interface using the CLI

Before You Begin

You must use the following steps to configure management interfaces on the controller. You can also use these steps to configure the AP manager interfaces on the controller. These general instructions apply to all management interfaces.

SUMMARY STEPS

    1.    show ip interface brief

    2.    config terminal

    3.    wireless management interface vlan vlanID

    4.    end

    5.    show wireless interface summary


DETAILED STEPS
      Command or Action Purpose
    Step 1 show ip interface brief
     

    Displays all the interfaces in the controller.

     
    Step 2 config terminal
     

    Enters global configuration mode.

     
    Step 3 wireless management interface vlan vlanID
     

    Creates a management interface by providing the values for the VLAN (VLAN identifier).

     
    Step 4 end
     

    Returns to EXEC mode.

     
    Step 5 show wireless interface summary
     

    Displays all the wireless interfaces in the controller.
