AF-5X User Guide
Ubiquiti Networks, Inc.
-
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.
