Chapter 6: Network Tab
The Network tab allows you to configure settings for the management network.
There are two ways to access the airFiber Configuration
Interface:
•
Management Port
Enabled by default. Use a direct connection to the Management port for out-of-band management.
•
In-Band Management
Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.
The Management port and in-band management share the default IP address of 192.168.1.20.
Change
To save or test your changes, click Change.
A new message appears. You have three options:
•
Apply
To immediately save your changes, click Apply.
•
Test
To try the changes without saving them, click
Test. To keep the changes, click Apply. If you do not click Apply within 180 seconds (the countdown is displayed), the AF-5X times out and resumes its earlier configuration.
•
Discard
To cancel your changes, click Discard.
Management Network Settings
In-Band Management
Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.
Note: If In-Band Management is enabled, ensure that each airFiber radio of a link has a unique IP Address. If the airFiber radios use the same IP Address, then you may lose access via the Data ports.
Management IP Address
The AF-5X can use a static IP address or obtain an IP address from its DHCP server.
•
DHCP
Keep the default, DHCP, to use DHCP reservation on your router to assign a unique IP Address. The local
Ubiquiti Networks, Inc.
DHCP server assigns a reserved IP address, gateway IP address, and DNS address to the AF-5X.
Note: If you select the DHCP option, ensure that you use DHCP reservation because if you do not know the IP address, then the only way to manage the AF-5X is to reset the AF-5X to its factory default settings. (Press and hold the Reset button for more than five seconds.) Its default Management IP
Address is reset to 192.168.1.20.
-
DHCP Fallback IP
Specify the IP address the AF-5X should use if a DHCP server is not found.
-
DHCP Fallback Netmask
Specify the netmask the
AF-5X should use if a DHCP server is not found.
•
Static
Assign static IP settings to the AF-5X.
Note: IP settings should be consistent with the address space of the AF-5X’s network segment.

AF-5X User Guide
-
IP Address
Specify the IP address of the AF-5X. This IP will be used for device management purposes.
-
Netmask
When the netmask is expanded into its binary form, it provides a mapping to define which portions of the IP address range are used for the network devices and which portions are used for host devices. The netmask defines the address space of the AF-5X’s network segment. The 255.255.255.0 (or
“/24”) netmask is commonly used on many Class C IP networks.
-
Gateway IP
Typically, this is the IP address of the host router, which provides the point of connection to the
Internet. This can be a DSL modem, cable modem, or
WISP gateway router. The AF-5X directs data packets to the gateway if the destination host is not within the local network.
-
Primary DNS IP
Specify the IP address of the primary
DNS (Domain Name System) server.
-
Secondary DNS IP
Specify the IP address of the secondary DNS server. This entry is optional and used only if the primary DNS server is not responding.
Management VLAN
If enabled, automatically creates a management Virtual Local Area Network (VLAN).
•
VLAN ID
Enter a unique VLAN ID from 2 to 4094.
Auto IP Aliasing
If enabled, automatically generates an
IP address for the corresponding WLAN/LAN interface.
The generated IP address is a unique Class B IP address from the 169.254.X.Y range (netmask 255.255.0.0), which is intended for use within the same network segment only.
The Auto IP always starts with 169.254.X.Y, with X and Y as the last two octets from the MAC address of the AF-5X.
For example, if the MAC address is 00:15:6D:A3:04:FB, then the generated unique Auto IP will be 169.254.4.251. (The hexadecimal value, FB, converts to the decimal value, 251.)
The Auto IP Aliasing setting can be useful because you can still access and manage devices even if you lose, misconfigure, or forget their IP addresses. Because an
Auto IP address is based on the last two octets of the MAC address, you can determine the IP address of a device if you know its MAC address.
airView Port
The port number associated with the airView spectrum analyzer tool. The default value is 18888.
