Setting Up the Wireless AP Using Static Configuration

Static configuration settings allow you to set up branch office support. These settings can be employed whenever required, and are not dependent on branch topology. In the branch office model, while the controller is at a central office, APs are installed in remote sites. The APs must be able to interact in both the local site network and the central office network. When this is the case, a static configuration is recommended.

For initial configuration of a wireless AP to use a static IP address assignment:

  • Allow the AP to first obtain an IP address using DHCP (Dynamic Host Configuration Protocol). By default, APs are configured to use the DHCP IP address configuration method.
  • Allow the AP to connect to the controller using the DHCP assigned IP address.
  • After the AP has successfully registered to the controller, use the Static Configuration tab to configure a static IP address for the AP, and then save the configuration.
  • Once the static IP address has been configured on the AP, the AP can then be moved to its target location, if applicable.
    Note

    Note

    If a wireless AP with a statically configured IP address (without a statically configured Wireless Controller Search List) cannot register with the controller within the specified number of retries, the wireless AP uses SLP, DNS, and SLP multicast as a backup mechanism.

To set up a wireless AP using static configuration:

  1. From the top menu, click AP. The AP screen displays.
  2. Click the appropriate wireless AP in the list (not the checkbox). The AP dashboard displays.
  3. Click Configure. The AP Properties tab displays.
  4. Click the Static Configuration tab.
  5. Configure the following parameters:
    1. Select a VLAN (Virtual LAN) setting for the AP.
      Caution

      Caution

      Caution should be exercised when using this feature. For more information, see Configuring VLAN Tags for Wireless APs.If the Wireless AP VLAN is not configured properly (wrong tag), connecting to the AP may not be possible. To recover from this situation, you need to reset the AP to its factory default settings. For more information, see the Extreme Networks ExtremeWireless Maintenance Guide .
    2. Select a method of IP address assignment for the AP.

      Static Configuration Properties

      Field/Button Description
      VLAN Settings
      Tagged Select if you want to assign this AP to a specific VLAN and type the value in the box.
      Untagged Select if you want this AP to be untagged. This option is selected by default.
      VLAN ID Enter a VLAN ID. Valid values are 2 to 4094
      IP Address Assignment
      Use DHCP Select to enable Dynamic Host Configuration Protocol (DHCP). This option is enabled by default.
      Static Values Select to specify the IP address of the AP.
      IP Address Type the IP address of the AP.
      Netmask Type the appropriate subnet mask to separate the network portion from the host portion of the address.
      Gateway Type the default gateway of the network.
      Ethernet Port
      Ethernet Speed If the AP has an Ethernet port, select values in the Ethernet Speed and Ethernet Mode drop down lists.
      Ethernet Mode If the AP has an Ethernet port, select values in the Ethernet Speed and Ethernet Mode drop down lists.
      Tunnel MTU Enter a static MTU value, from 600 to 1500, in the Tunnel MTU box. The maximum MTU can be increased to 1800 bytes by enabling Jumbo Frames support (for more information, see Setting Up the Data Ports). If the wireless software cannot discover the MTU size, it enforces the static MTU size. Set the MTU size to allow the source to reduce the packet size and avoid the need to fragment data packets in the tunnel.
      LACP Applies to the AP38xx and AP39xx only. Click to Enable Link Aggregation Control Protocol. This feature allows higher throughput by combining the two Ethernet ports. This feature is disabled by default.
      Wireless Controller Search List
      Up Select a controller and click the Up button to modify the order of the controllers. When an AP searches for a controller to register with, it begins with the first controller in the list.
      Down Select a controller and click the Up button to modify the order of the controllers. When an AP searches for a controller to register with, it begins with the first controller in the list.
      Delete Click to remove the controller from the list so that it can no longer control the AP.
      Add In the Add box, type the IP address of the controller that will control this AP then click the Add button to add the IP address is added to the list. Repeat this process to add the IP addresses of up to three controllers.

      This feature allows the AP to bypass the discovery process. If the Wireless Controller Search List box is not populated, the AP uses SLP unicast/multicast, DNS, or DHCP vendor option 43 to discover a controller.

      For the initial AP deployment, it is necessary to use one of the described options in Discovery and Registration.

      Additional Buttons
      Copy to Defaults To make this AP‘s configuration be the system‘s default AP settings, click Copy to Defaults. A pop-up dialog asking you to confirm the configuration change is displayed.To confirm resetting the system‘s default AP settings, click OK.
      Reset to Defaults If you have an AP that is already configured with its own settings, but would like the AP to be reset to use the system‘s default AP settings, use the Reset to Defaults feature
      Apply Click to save your changes.
