Chapter 1: Advanced Tab
The Advanced tab handles advanced wireless and Ethernet
settings. These settings should not be changed unless you
know the effects the changes will have on the AF-5X.
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.
Wireless Settings
GPS Clock Sync The airFiber uses GPS to synchronize
the timing of its transmissions. By default, this option is
disabled.
DATA Port Ethernet Settings
DATA Speed This is the speed of the Data port. By default,
the option is Auto. The AF-5X 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 AF-5X generates and
responds to Ethernet layer PAUSE frames. The AF-5X
regulates inbound traffic from the customer’s network
to avoid buffer overflows within the AF-5X. 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 AF-5X 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’s
management interface CPU.
Track Radio Link If this option is enabled, the AF-5X
disconnects the Data port’s Ethernet link when the RF link
is lost (The Management port is never disabled by this
option). The Track Radio Link option is useful because it
quickly indicates a “link lost” condition to the customer’s
routing equipment (such as a direct connection to
OSPF-enabled routers).
