Network

This describes how you can configure the management IP address and VLAN settings of your NWA/WAC.

Management Mode

This discusses using the NWA/WAC in management mode, which determines whether the NWA/WAC is used in its standalone mode, or as part of a Control And Provisioning of Wireless Access Points (CAPWAP) network.

About CAPWAP

The NWA/WAC supports CAPWAP. This is ZyXEL’s implementation of the CAPWAP protocol (RFC 5415).

Note: The NWA/WAC can be a standalone AP (default), or a CAPWAP managed AP.

Managed AP Finds the Controller

A managed NWA/WAC can find the controller in one of the following ways:

• Manually specify the controller’s IP address in the Web Configurator’s AC (AP Controller) Discovery screen.

• Get the controller’s IP address from a DHCP server with the controller’s IP address configured as option 138.

• Get the controller’s IP address from a DNS server SRV (Service) record.

• Broadcasting to discover the controller within the broadcast domain.

Note: The AP controller needs to have a static IP address. If it is a DHCP client, set the DHCP server to reserve an IP address for the AP controller.

CAPWAP and IP Subnets

By default, CAPWAP works only between devices with IP addresses in the same subnet.

However, you can configure CAPWAP to operate between devices with IP addresses in different subnets by doing the following.

• Activate DHCP. Your network’s DHCP server must support option 138 defined in RFC 5415.

• Configure DHCP option 138 with the IP address of the CAPWAP AP controller on your network.

DHCP Option 138 allows the CAPWAP management request (from the AP in managed AP mode) to reach the AP controller in a different subnet.

Notes on CAPWAP

This section lists some additional features of ZyXEL’s implementation of the CAPWAP protocol.

• When the AP controller uses its internal Remote Authentication Dial In User Service (RADIUS) server, managed APs also use the AP controller’s authentication server to authenticate wireless clients.

• If a managed AP’s link to the AP controller is broken, the managed AP continues to use the wireless settings with which it was last provided.

IP Setting

Use this screen to configure the IP address for your NWA/WAC.

Configuration > Network > IP Setting
Label	Description
IP Address Assignment
Get Automatically	Select this to make the interface a DHCP client and automatically get the IP address, subnet mask, and gateway address from a DHCP server.
Use Fixed IP Address	Select this if you want to specify the IP address, subnet mask, and gateway manually.
IP Address	Enter the IP address for this interface.
Subnet Mask	Enter the subnet mask of this interface in dot decimal notation. The subnet mask indicates what part of the IP address is the same for all computers in the network.
Gateway	Enter the IP address of the gateway. The NWA/WAC sends packets to the gateway when it does not know how to route the packet to its destination. The gateway should be on the same network as the interface.
DNS Server IP Address	Enter the IP address of the DNS server.
IPv6 Address Assignment
Enable Stateless Address Auto-configuration (SLAAC)	Select this to enable IPv6 stateless auto-configuration on the NWA/WAC. The NWA/WAC will generate an IPv6 address itself from a prefix obtained from an IPv6 router in the network.
Link-Local Address	This displays the IPv6 link-local address and the network prefix that the NWA/WAC generates itself for the LAN interface.
IPv6 Address/Prefix Length	Enter the IPv6 address and the prefix length for the LAN interface if you want to use a static IP address. This field is optional. The prefix length indicates what the left-most part of the IP address is the same for all computers in the network, that is, the network address.
Gateway	Enter the IPv6 address of the default outgoing gateway using colon (:) hexadecimal notation.
Metric	Enter the priority of the gateway (if any) on the LAN interface. The NWA/WAC decides which gateway to use based on this priority. The lower the number, the higher the priority. If two or more gateways have the same priority, the NWA/WAC uses the one that was configured first.
DHCPv6 Client	Select this option to set the NWA/WAC to act as a DHCPv6 client.
DUID	This field displays the DHCP Unique IDentifier (DUID) of the NWA/WAC, which is unique and used for identification purposes when the NWA/WAC is exchanging DHCPv6 messages with others.
Request Address	Select this option to get an IPv6 address from the DHCPv6 server.
DHCPv6 Request Options	Select this option to determine what additional information to get from the DHCPv6 server.
DNS Server	Select this option to obtain the IP address of the DNS server.
NTP Server	Select this option to obtain the IP address of the NTP server.
Apply	Click Apply to save your changes back to the NWA/WAC.
Reset	Click Reset to return the screen to its last-saved settings.

VLAN

A Virtual Local Area Network (VLAN) allows a physical network to be partitioned into multiple logical networks. Devices on a logical network belong to one group. A device can belong to more than one group. With VLAN, a device cannot directly talk to or hear from devices that are not in the same group(s); the traffic must first go through a router.

Use this screen to configure the VLAN settings for your NWA/WAC.

Configuration > Network > VLAN
Label	Description
VLAN Settings
Management VLAN ID	Enter a VLAN ID for the NWA/WAC.
As Native VLAN	Select this option to treat this VLAN ID as a VLAN created on the NWA/WAC and not one assigned to it from outside the network.
LAN Setting
Port Setting
Edit	Double-click an entry or select it and click Edit to open a screen where you can modify the entry’s settings. In some tables you can just click a table entry and edit it directly in the table. For those types of tables small red triangles display for table entries with changes that you have not yet applied.
Activate/Inactivate	To turn on an entry, select it and click Activate. To turn off an entry, select it and click Inactivate.
#	This is the index number of the port.
Status	This field indicates whether the port is enabled (a yellow bulb) or not (a gray bulb).
Port	This field displays the name of the port.
PVID	This field displays the port number of the VLAN ID.
VLAN Configuration
Add	Click this to create a new entry. For features where the entry’s position in the numbered list is important (features where the NWA/WAC applies the table’s entries in order like the SSID for example), you can select an entry and click Add to create a new entry after the selected entry.
Edit	Double-click an entry or select it and click Edit to open a screen where you can modify the entry’s settings. In some tables you can just click a table entry and edit it directly in the table. For those types of tables small red triangles display for table entries with changes that you have not yet applied.
Remove	To remove an entry, select it and click Remove. The NWA/WAC confirms you want to remove it before doing so.
Activate/Inactivate	To turn on an entry, select it and click Activate. To turn off an entry, select it and click Inactivate.
#	This is the index number of the VLAN ID
Status	This field indicates whether the VLAN is enabled (a yellow bulb) or not (a gray bulb).
Name	This field displays the name of each VLAN.
VID	This field displays the VLAN ID.
Member	This field displays the VLAN membership to which the port belongs.
Apply	Click Apply to save your changes back to the NWA/WAC.
Reset	Click Reset to return the screen to its last-saved settings.

AC (AP Controller) Discovery

You can have the NWA/WAC managed by an AP controller on your network. When you do this, the NWA/WAC can be configured ONLY by the AP controller. See Management Mode for more information on management mode and AP Controller.

If you want to return the NWA/WAC to standalone AP mode, you can do one of the two following options:

• Press the Reset button.

• Check the AP controller for the NWA/WAC’s IP address and use FTP to upload the default configuration file to the NWA/WAC. You can get the configuration file at conf/system-default.conf. You must reboot the device after uploading the configuration file.

Configuration > Network > AC Discovery
label	description
Discovery Setting
Auto	Select this option to use DHCP option 138/DNS SRV record/Broadcast to get the AP controller’s IP address.
Manual	Select this option and enter the IP address of the AP controller manually. This is necessary when the AP Controller is not in the same subnet and you want it to manage the NWA/WAC.
Primary / Secondary Static AC IP	Specify the primary and secondary IP address of the AP controller to which the NWA/WAC connects.
Disable	Select this to manage the NWA/WAC using its own web configurator, neither managing nor managed by other devices. Please note if an AP Controller is in the same subnet, you will need to click Disable if you do not want the NWA/WAC to be managed.
Apply	Click Apply to save the information entered in this screen. If you change the mode in this screen, the NWA/WAC restarts. Wait a short while before you attempt to log in again. If you changed the mode to Managed AP, the AP controller uploads the firmware package for managed AP mode to the NWA/WAC and you cannot log in as the web configurator is disabled; you must manage the NWA/WAC through the AP controller on your network.
Reset	Click Reset to return the screen to its last-saved settings.
