Ubiquiti Networks, Inc.

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).
