Chapter 7: 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 airFiber
AF24.
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 airFiber AF24 times out and resumes its earlier
configuration.
• Discard To cancel your changes, click Discard.
Advanced Wireless Settings
GPS Clock Synchronization 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 airFiber AF24
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. To achieve full performance with extra-
long Ethernet cables, ensure that you use CAT6 qualified
cables and interconnects.
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 AF24 generates and
responds to Ethernet layer PAUSE frames. The airFiber
AF24 regulates inbound traffic from the customer’s
network to avoid buffer overflows within the airFiber
AF24. Flow control has the effect of controlling the
inter-packet spacing of packets headed into the airFiber
Data interface.
