Note: IP settings should be consistent with the
address space of the airFiber X radio’s network
segment.
- IP Address Specify the IP address of the airFiber X
radio. 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
airFiber X radio’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 airFiber X radio 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 airFiber X radio. 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.
airFiber AF-11FX User Guide
Mgmt Speed This is the speed of the Management
port. By default, the option is Auto. The airFiber X radio
automatically negotiates transmission parameters, such as
speed and duplex, with its counterpart. In this process, the
networked devices first share their capabilities and then
choose the fastest transmission mode they both support.
To manually specify the maximum transmission link speed
and duplex mode, select one of the following options:
100
Mbps-Full , 100 Mbps-Half , 10 Mbps-Full , or 10 Mbps-
Half. If you are running extra long Ethernet cables, a link
speed of 10 Mbps could help to achieve better stability.
Full-duplex mode allows communication in both
directions simultaneously. Half-duplex mode allows
communication in one direction at a time, alternating
between transmission and reception.
Data Port Ethernet Settings
DATA Speed This is the speed of the Data port.
The default is Auto , which allows the radio to operate
at a speed of 1 Gbps. The airFiber X radio automatically
negotiates transmission parameters, such as speed and
duplex, with its counterpart. In this process, the networked
devices first share their capabilities and then choose the
fastest transmission mode they both support.
To manually specify the maximum transmission link
speed and duplex mode, select one of the following
options:
100 Mbps-Full , 100 Mbps-Half , 10 Mbps-Full , or
10 Mbps-Half .
Full-duplex mode allows communication in both
directions simultaneously. Half-duplex mode allows
communication in one direction at a time, alternating
between transmission and reception.
Flow Control If enabled, the airFiber X radio generates
and responds to Ethernet layer PAUSE frames. The
airFiber X radio regulates inbound traffic from the
customer’s network to avoid buffer overflows within the
airFiber X radio. Flow control has the effect of controlling
the inter-packet spacing of packets headed into the
airFiber Data interface.
Multicast Filter If enabled, the filter blocks multicast
traffic from overloading the CPU when in-band
management is enabled. This allows the airFiber X radio
to be managed in-band when the customer’s network is
carrying large volumes of multicast traffic, such as IPTV.
The filter does not block multicast traffic going over the
radio; it simply blocks it from reaching the airFiber X
radio’s management interface CPU.
