System Configuration Overview
The following section provides
a high-level overview of the steps involved in the initial configuration of ExtremeWireless:
- Before you begin
the configuration process, research the type of WLAN (Wireless Local Area Network)
deployment that is required. For example, topology and VLAN (Virtual LAN) IDs, SSIDs,
security requirements, and filter roles.
- Prepare the network servers.
Ensure that the external servers, such as DHCP (Dynamic Host Configuration Protocol) and
RADIUS servers (if applicable) are available and appropriately configured.
- Install the controller. For more information, see the documentation for your controller.
- Perform the first
time setup of the controller on the physical network, which includes configuring the
IP addresses of the interfaces on the controller.
- Create a
new physical topology and provide the IP address to be the relevant subnet
point of attachment to the existing network.
- To
manage the controller through the interface configured above, select the
Mgmt checkbox on the Interfaces tab.
- Configure the data port interfaces to be on separate VLANs, matching the
VLANs configured in Step 3 above. Ensure also that the tagged vs. untagged
state is consistent with the switch port configuration.
- Configure the time zone. Because changing the time zone requires restarting
the controller, it is recommended that you configure the time zone during
the initial installation and configuration of the controller to avoid
network interruptions. For more information, see Configuring Network Time.
- Apply an
activation key file. If an activation key is not applied, the controller
functions with some features enabled in demonstration mode. Not all features
are enabled in demonstration mode. For example, mobility is not enabled and
cannot be used.
Caution
Whenever the
licensed region changes on the
ExtremeWireless Appliance, all APs are changed to Auto Channel Select to
prevent possible infractions to local RF regulatory requirements. If
this occurs, all manually configured radio channel settings will be
lost.Installing the new license key before upgrading will prevent the
ExtremeWireless Appliance from changing the licensed region, and in
addition, manually configured channel settings will be maintained. For
more information, see the
ExtremeWireless Maintenance Guide.
- Configure the
controller for remote access:
- Set up
an administration station (laptop) on subnet 192.168.10.0/24. By default,
the controller's Management interface is configured with the static IP
address 192.168.10.1.
- Configure the controller‘s management interface.
- Configure the data interfaces.
- Set up
the controller on the network by configuring the physical data ports.
- Configure the routing table.
- Configure static routes or OSPF (Open Shortest Path First) parameters, if
appropriate to the network.
For more information, see
Configuring the ExtremeWireless Appliance for the First Time.
- Configure the
traffic topologies your network must support. Topologies represent the controller‘s
points of network attachment, and therefore VLANs and port assignments need to be
coordinated with the corresponding network switch ports. For more information, see
Configuring a Basic Data Port Topology.
- Configure roles.
Roles are typically bound to topologies. Role application assigns user traffic to
the corresponding network point.
- Configure WLAN
services.
- Create the
VNSs.
A VNS
binds a WLAN Service to a Role that will be used for default assignment upon a
user‘s network attachment.
You can create topologies, roles, and WLAN services first,
before configuring a VNS, or you can select one of the wizards (such as the VNS
wizard), or you can simply select to create new VNS.
The VNS page then allows for
in-place creation and definition of any dependency it may require, such
as:
- Install,
register, and assign APs to the VNS.
- Confirm
the latest firmware version is loaded. For more information, see Performing AP Software Maintenance.
- Deploy
APs to their corresponding network locations.
- If
applicable, configure a default AP template for common radio assignment,
whereby APs automatically receive complete configuration. For typical
deployments where all APs are to have the same configuration, this feature
will expedite deployment, as an AP will automatically receive full
configuration (including VNS-related assignments) upon initial registration
with the controller. If applicable, modify the properties or settings of the
APs. For more information, see Configuring the ExtremeWireless APs.
- Connect
the APs to the controller.
- Once the
APs are powered on, they automatically begin the Discovery process of the
controller, based on factors that include:
- Their Registration mode (on the AP
Registration screen)
- The enterprise network services that will support the discovery
process
