Configure Neighboring Devices

Roaming Threshold helps control the number of tunnels an AP can accept during layer 3 roaming operations.

Manually add a Neighbor to define a Hive neighbor in the case where the APs cannot hear over the air and they are in different management subnets (which is how they ordinarily learn of each other.) Bonjour Gateway piggybacks on this functionality to learn of APs in other management subnets that cannot be heard over the air.

  1. Go to Manage > Devices and select the host name of the AP in the Devices list.
  2. From the Device Details left pane, select Configure.
  3. Under Additional Settings, select Neighboring Devices.
  4. Select a Roaming Threshold value from the drop-down list to set the volume of traffic that the selected neighbors will accept through GRE (Generic Routing Encapsulation) tunnels to support Layer 3 roaming.

    This option gives hive members the ability to push tunnels to other members for better tunnel load balancing. For example, if one AP near an entrance gets overloaded with tunnels, you can lower its threshold to medium or low so that more tunnels terminate on other APs.

    Note

    Note

    This setting only takes effect when the APs function as portals and Layer 3 roaming is enabled.
  5. Select Add to manually add a Layer 3 roaming or Bonjour gateway neighboring Extreme Networks device.
  6. Select an Available Neighbor device from the drop-down list and select Add.
    Note

    Note

    You can add any or all of the Layer 3 roaming and Bonjour gateway neighboring Extreme Networks devices by repeating the previous two steps.
  7. To remove a manually configured neighboring device, select a device, and then select Delete.
  8. Select Save Neighboring Devices.
  9. To update the device immediately, select Update.
  10. Select the type of update, and then select Save as Defaults to save this option as the default action.
  11. To update the device immediately, select Perform Update.
