17Chapter 5: Wireless TabairFiber X User GuideUbiquiti Networks, Inc.Chapter 5: Wireless TabThe Wireless tab contains options to set up the wireless part of the link. This includes wireless mode, link name, frequencies, output power, speed, and wireless security.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X radio times out and resumes its earlier configuration.• Discard To cancel your changes, click Discard.Write down the settings you configure on the Wireless tab. You will need to enter the same settings on the airFiberX radio at the other end of your PtP link. The exceptions are as follows:• Wireless Mode Configure one airFiberX radio as the Master and the other as the Slave. Basic Wireless SettingsIn this section, configure the basic wireless settings, such as wireless mode, link name, country code, frequencies, output power, speed, and gain.Wireless Mode By default, the Wireless Mode is Slave. You must configure one airFiberX radio as Master because each PtP link must have one Master.Link Name Enter a name for your PtP link. This name must be the same on both Master and Slave radios in order for them to connect.
18Chapter 5: Wireless Tab airFiber X User GuideUbiquiti Networks, Inc.Country Code Each country has its own power level and frequency regulations. To ensure the airFiberX radio operates under the necessary regulatory compliance rules, you must select the country where your device will be used. The frequency settings and output power limits will be tuned according to the regulations of the selected country. For details, refer to this table, “Frequency Ranges and Power Levels per Country/Region” on page 63.This radio is restricted to use with a license and to use only in certain EU countries or geographical areas of EU countries. • Change To select a new country, click Change.Note: U.S. product versions are locked to the U.S. Country Code to ensure compliance with FCC regulations. - Country Select the new country. - I agree to these terms of use Check this box; you must agree to the Terms of Use to use the product. - Accept Saves your change. - Cancel Discards your change. Channel Bandwidth Select the appropriate channel size:• AF-2X and AF-3X: 3.5, 5, 7, 10, 14, 20, 28, 30, 40, 50, or 56 MHz• AF-5X only: 5, 10, 20, 30, 40, or 50 MHzNote:. The available channel bandwidths depend on the regulatory requirements of the currently selected country or region.Frame Length (Available on AF-2X and AF-3X only.) Use this to specify the frame length of the radio: default, 2.0ms, 2.5ms, 4.0ms, or 5ms. The frame length must be the same on both Master and Slave radios. The default value corresponds to 5ms for the 3.5MHz and 5MHz bandwidths, or 2.0ms for all other bandwidths.Note:. The AF-5X uses a frame length of 2.0ms (this value cannot be changed).Master TX Duty Cycle Use this to change the duty cycle of the RF link (the Master’s TX percentage). Choose one of the following values: 25%, 33%, 50%, 67%, or 75%. Output Power (EIRP) Defines the maximum average transmit output power (in dBm) of the airFiberX radio. To specify the output power, use the slider or manually enter the output power value. The transmit power level maximum is limited according to country regulations.Note: The Antenna Gain and Cable Loss should be configured before the Output Power. This is because the range of the Output Power field is affected by the Antenna Gain and Cable Loss values – changing the antenna gain or cable loss adjusts the maximum and minimum values you can select using the Output Power slider. Since the Output Power already includes the antenna gain and cable loss, it represents EIRP; therefore, the value of Output Power is actually the total power the radio is transmitting over the air. The current transmit power is displayed by the TX Power EIRP setting on the Main tab.Note: The airFiberX radio may limit the output power to a value less than the value specified by this field, to comply with regulatory region requirements. For a list of maximum output power values by country and region, refer to “Frequency Ranges and Power Levels per Country/Region” on page 49.Antenna Gain Enter the gain in dBi of the antenna that is used in your installation. An improper value could cause DFS false detections when operating on DFS frequencies.Cable Loss Enter the cable loss in dB of the cable that is used in your installation. An improper value could cause DFS false detections when operating on DFS frequencies.Note: If you are using the airFiber AF-5X radio with an airFiber NxN Multiplexer, set the CableLoss to a value that includes the additional cable loss due to the Multiplexer. The additional cable loss (in dB) is:• 4.1 for the AF-MPx4, or• 7.2 for the AF-MPx8Maximum Modulation Rate or Modulation Rate Higher modulations support greater throughput but generally require stronger RF signals and a higher Signal-to-Noise Ratio (SNR). By default, Automatic Rate Adaptation is enabled, and Maximum Modulation Rate is displayed. This allows the airFiberX radio to automatically adjust the modulation rate to changing RF signal conditions. Under certain conditions, you may prefer to lock the Maximum Modulation Rate to a lower setting to improve link performance. When Automatic Rate Adaptation is disabled, Modulation Rate is displayed. Lock the Modulation Rate to the setting of your choice.
19Chapter 5: Wireless TabairFiber X User GuideUbiquiti Networks, Inc.Select one of the available modulation rates:• 8x (256QAM MIMO)• 6x (64QAM MIMO)• 4x (16QAM MIMO)• 2x (QPSK MIMO)• 1x (½ Rate QPSK xRT) • ¼x (¼ Rate QPSK xRT)Frequency SettingsThe Valid Frequencies for your Country Code selection are displayed. Ensure that you use frequencies that comply with the local country regulations.TDD Split Frequency Mode This option lets you configure separate frequencies for TX and RX. To configure split frequencies, enable this option and select a different RX frequency on each side of the link. This feature is useful if both sides of the link do not have a common, clean frequency. It is important for the RX frequency to be clean; if different frequencies are clean on each end of the link, select the clean RX frequency on each end.AF-2X Split Frequency SettingsAF-3X Split Frequency SettingsAF-5X Split Frequency SettingsNote for AF-5X only: Split frequency mode is not available in DFS bands because the RX frequency must match the TX frequency to allow the receiver to scan for DFS on the TX frequency. In regions where both DFS and non-DFS frequencies are available, enabling split frequencies will disable any DFS band frequencies. In regions where only DFS frequencies are available, there will be no option to turn on split frequencies.Frequency Enter a valid frequency. The current state is displayed.Note: The Master and Slave should have the same Frequency setting. Wireless SecurityairFiber uses 128-bit, AES (Advanced Encryption Standard) encryption at all times.Key Type Specifies the character format.• HEX By default, this option uses hexadecimal characters. 0-9, A-F, or a-f are valid characters.• ASCII ASCII uses the standard English alphabet and numeric characters (0-9, A-Z, or a-z). Key Select the format of the MAC address.• HEX Enter 16bytes (eight, 16-bit HEX values). You can omit zeroes and use colons, similar to the IPv6 format. The default is: 0000:0000:0000:0000:0000:0000:0000:0000Note: The airFiber Configuration Interface supports IPv6 formats excluding dotted quad and “::” (double-colon) notation.• ASCII Enter a combination of alphanumeric characters. Using 128-bit SHA1 (Secure Hash Algorithm 1), the airFiberX radio hashes the ASCII key to create a 128-bit key for AES.

21Chapter 6: Network Tab airFiber X User GuideUbiquiti Networks, Inc.Chapter 6: Network Tab The Network tab allows you to configure settings for the management network. There are two ways to access the airFiber Configuration Interface:• Management Port Enabled by default. Use a direct connection to the Management port for out-of-band management.• In-Band Management Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.The Management port and in-band management share the default IP address of 192.168.1.20.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X radio times out and resumes its earlier configuration.• Discard To cancel your changes, click Discard.Management Network SettingsIn-Band Management Enabled by default. In-band management is available through the local Data port or the Data port at the other end of the link.Note: If In-Band Management is enabled, ensure that each airFiberX radio in a link has a unique IP Address. If the airFiberX radios use the same IP Address, you may lose access via the Data ports.Management IP Address The airFiberX radio can use a static IP address or obtain an IP address from its DHCP server.• DHCP Keep the default, DHCP, to use DHCP reservation on your router to assign a unique IP Address. The local DHCP server assigns a reserved IP address, gateway IP address, and DNS address to the airFiberX radio.Note: If you select the DHCP option, ensure that you use DHCP reservation because if you do not know the IP address, then the only way to manage the airFiberX radio is to reset the airFiberX radio to its factory default settings. (Press and hold the Reset button for more than five seconds.) Its default Management IP Address is reset to 192.168.1.20. - DHCP Fallback IP Specify the IP address the airFiberX radio should use if a DHCP server is not found. - DHCP Fallback Netmask Specify the netmask the airFiberX radio should use if a DHCP server is not found.• Static Assign static IP settings to the airFiberX radio.Note: IP settings should be consistent with the address space of the airFiberX radio’s network segment.
22Chapter 6: Network Tab airFiber X User GuideUbiquiti Networks, Inc. - 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.airView Port The port number associated with the airView spectrum analyzer tool. The default value is 18888. For detailed information on the airView tool, refer to “airView” on page 36.
23Chapter 7: Advanced Tab airFiber X User GuideUbiquiti Networks, Inc.Chapter 7: Advanced Tab The Advanced tab handles advanced wireless and Ethernet settings. These settings should not be changed unless you understand how the changes will affect the airFiberX radio.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X radio times out and resumes its earlier configuration.• Discard To cancel your changes, click Discard.Wireless SettingsGPS Clock Sync The airFiber uses GPS to synchronize the timing of its transmissions. By default, this option is disabled.Automatic Power Backoff This feature allows the radio to automatically adjust the maximum TX power per modulation so that the radio never transmits at a higher power than each modulation rate can decode. The default values in the Max 8x/6x/4x Conducted Power fields are values determined to work at all temperatures and all frequencies supported by the radio.It may, however, be possible to increase the maximum TX power for one or more modulations based on your radio’s operating environment. For example, if a radio is running at 6x and trying to switch into 8x operation, you can increase the Max 8x Conducted Power value 1dB at a time to see if the radio can maintain 8x operation (Automatic Power Backoff must be enabled to allow the Max Conducted Power fields to be edited). The same can be done with 6x and 4x up to the maximum conducted power of the radio.Max 8x/6x/4x Conducted Power The maximum conducted power for the 8x/6x/4x modulation rates. Each field is editable only if Automatic Power Backoff is enabled.
24Chapter 7: Advanced Tab airFiber X User GuideUbiquiti Networks, Inc.DATA Port Ethernet SettingsDATA Speed This is the speed of the Data port. Thedefault 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. To disable the Ethernet data port, select Disabled. Note: If Disabled is selected, ensure that the radio is accessible using the Management Ethernet port or over the RF link (with in-band management enabled), or all communication with the radio will be lost.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’s management interface CPU.Track Radio Link If this option is enabled, the airFiberX radio 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). • Disabled The Track Radio Link option is disabled by default. The Data port’s Ethernet link will always remain up regardless of the RF link state.• Use Timeout Duration This option is designed for use by operators who are using in-band management. Two timers control the Data port’s Ethernet link.RF Link Ethernet Link NotesGoes down for the first timeThe Ethernet link goes down and remains down for the number of seconds specified by the Link Off Duration timer. The Ethernet link will then come back up so that the airFiberX radio can be managed even when the RF link is down. Even if the RF link goes back up before the Link Off Duration timer elapses, the Ethernet link remains down. The Ethernet link’s downtime is long enough to signal to the customer’s routing equipment that the path is lost. Goes down for the secondtimeThe Ethernet link remains up as long as time remains on the Link Off Spacing timer.When the Link Off Spacing timer elapses, then the Ethernet link goes down again for the number of seconds specified by the Link Off Duration timer. (This happens only if the RF link is still down.)The Ethernet link’s uptime is long enough so the operator has enough time to access the airFiberX radio, make configuration changes, and save those changes. Sufficient Ethernet link uptime is vital when a RF link is constantly up and down.If the Use Timeout Duration option is enabled, the Track Radio Link option and the following timers are enabled: - Link Off Duration The Link Off Duration timer controls the length of time the Data port’s Ethernet link will be down if the RF link goes down. Enter the number of seconds that the Ethernet link should be offline. For example, if this is set to 10seconds, then when the RF link goes down, the Ethernet link will go down and remain down for 10seconds (regardless of the RF link state), and then it will go back up. - Link Off Spacing The Link Off Spacing timer controls the length of time the airFiberX radio will wait before allowing the Data port’s Ethernet link to go down for a second time if the RF link goes down again. Enter the minimum interval (in seconds) between offline events of the Ethernet link, regardless of the RF link status. The value for Link Off Spacing should be larger than the value for Link Off Duration, and it should be enough time for the operator to access the airFiberX radio, make any configuration changes, and apply those changes.Note: If the Link Off Spacing timer is set to 0seconds, then the Ethernet link will only use the Link Off Duration timer. If the Link Off Duration timer is set to 10 seconds and the RF link goes down, then the Ethernet link will go down for 10seconds and then go back up regardless of the RF link state. If the RF link is still down, then the Ethernet link will not go down again until the RF link goes back up and then down again.
25Chapter 7: Advanced Tab airFiber X User GuideUbiquiti Networks, Inc.Here are a couple of examples involving the use of the Use Timeout Duration option.• Example #1• Link Off Duration 5 seconds• Link Off Spacing 60 secondsThe Data port’s Ethernet link will be initially disconnected when the RF link first goes down. That event will start a 60-second timer. The Ethernet link will remain offline for 5seconds (regardless of the RF link status) and then come back online. The Ethernet link will remain online (regardless of the RF link state) until the 60-second timer expires.• Example #2• Link Off Duration 20 seconds• Link Off Spacing 120 secondsThe Data port’s Ethernet link will be initially disconnected when the RF link first goes down. That event will start a 120-second timer. The RF link goes back up after 10 seconds; however, that does not affect the Ethernet link. The Ethernet link will remain offline for 20seconds and then come back online. The RF link goes down again after 60 seconds; however, that does not affect the Ethernet link. The Ethernet link will then remain online until the 120-second timer expires.• Enabled This option is designed for use by operators who are not using in-band management. The Track Radio Link option is enabled without timers, so the Data port’s Ethernet link follows the RF link state exactly. If the RF link goes down, then the Ethernet link goes down and remains down until the RF link goes back up. Minimum TX Capacity This is the minimum allowable TX capacity before the link is dropped. If the capacity drops below this threshold, the Ethernet link will be dropped. Ifset to 0, then capacity will not be used; only the RF link state will be used.Minimum RX Capacity This is the minimum allowable RX capacity before the link is dropped. If the capacity drops below this threshold, the Ethernet link will be dropped. Ifset to 0, then capacity will not be used; only the RF link state will be used.Capacity Window This is the number of continuous seconds that the radio must remain under the minimum TX or RX capacity before the link is dropped. If set to 0, then as soon as capacity drops below a set limit, the Ethernet link will be dropped.MGMT Port Ethernet SettingsMGMT 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.

27Chapter 8: Services TabairFiber X User GuideUbiquiti Networks, Inc.Chapter 8: Services TabThe Services tab configures system management services: Ping Watchdog, SNMP Agent, Web Server, SSH Server, Telnet Server, NTP Client, Dynamic DNS, System Log, and Device Discovery.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X radio times out and resumes its earlier configuration.• Discard To cancel your changes, click Discard.Ping WatchdogPing Watchdog sets the airFiberX radio to continuously ping a user-defined IP address (it can be the Internet gateway, for example). If it is unable to ping under the user-defined constraints, the airFiberX radio will automatically reboot. This option creates a kind of “fail-proof” mechanism.Ping Watchdog is dedicated to continuous monitoring of the specific connection to the remote host using the Ping tool. The Ping tool works by sending ICMP echo request packets to the target host and listening for ICMP echo response replies. If the defined number of replies is not received, the tool reboots the airFiberX radio.Ping Watchdog Enables use of Ping Watchdog.• IP Address To Ping Specify the IP address of the target host to be monitored by Ping Watchdog.
28Chapter 8: Services Tab airFiber X User GuideUbiquiti Networks, Inc.• Ping Interval Specify the time interval (in seconds) between the ICMP echo requests that are sent by Ping Watchdog. The default value is 300 seconds.• Startup Delay Specify the initial time delay (in seconds) until the first ICMP echo requests are sent by Ping Watchdog. The default value is 300 seconds.The Startup Delay value should be at least 60 seconds as the network interface and wireless connection initialization takes a considerable amount of time if the airFiberX radio is rebooted.• Failure Count to Reboot Specify the number of ICMP echo response replies. If the specified number of ICMP echo response packets is not received continuously, Ping Watchdog will reboot the airFiberX radio. The default value is 3.• Save Support Info This generates a support information file.SNMP AgentSimple Network Monitor Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. Network administrators use SNMP to monitor network-attached devices for issues that warrant attention.The airFiberX radio contains an SNMP Agent, which does the following:• Provides an interface for device monitoring using SNMP• Communicates with SNMP management applications for network provisioning• Allows network administrators to monitor network performance and troubleshoot network problemsFor the purpose of equipment identification, configure the SNMP Agent with contact and location information:SNMP Agent Enables the SNMP Agent.• SNMP Community Specify the SNMP community string. It is required to authenticate access to Management Information Base (MIB) objects and functions as an embedded password. The airFiberX radio also supports a read-only community string; authorized management stations have read access to all the objects in the MIB except the community strings, but do not have write access. The airFiberX radio supports SNMP v1. The default SNMP Community is public.• Contact Specify the contact who should be notified in case of emergency.• Location Specify the airFiberX radio’s physical location.Web ServerThe following Web Server parameters can be set:Secure Connection (HTTPS) If enabled, the Web Server uses secure HTTPS mode. • Secure Server Port If secure HTTPS mode is used, specify the TCP/IP port of the Web Server.Server Port If HTTP mode is used, specify the TCP/IP port of the Web Server.Session Timeout Specifies the maximum timeout before the session expires. Once a session expires, you must log in again using the username and password.SSH ServerThe following SSH Server parameters can be set:SSH Server This option enables SSH access to the airFiberX radio.• Server Port Specify the TCP/IP port of the SSH Server.• Password Authentication If enabled, you must authenticate using administrator credentials to grant SSH access to the airFiberX radio; otherwise, an authorized key is required.• Authorized Keys Click Edit to import a public key file for SSH access to the airFiberX radio instead of using an admin password. - Choose File Click Choose File to locate the new key file. Select the file and click Open. - Import Imports the file for SSH access. - Enabled Enables the specific key. All added keys are saved in the system configuration file; however, only the enabled keys are active on the airFiberX radio. - Type Displays the type of key.

Telnet ServerThe following Telnet Server parameters can be set:Telnet Server This option activates Telnet access to the airFiberX radio.• Server Port Specify the TCP/IP port of the Telnet Server.NTP ClientNetwork Time Protocol (NTP) is a protocol for synchronizing the clocks of computer systems over packet-switched, variable-latency data networks. You can use it to set the system time on the airFiberX radio. If the Log option is enabled, then the system time is reported next to every log entry that registers a system event.NTP Client Enables the airFiberX radio to obtain the system time from a time server on the Internet.• NTP Server Specify the IP address or domain name of the NTP server.Dynamic DNSDomain Name System (DNS) translates domain names to IP addresses; Each DNS server on the Internet holds these mappings in its respective DNS database. Dynamic Domain Name System (DDNS) is a network service that notifies the DNS server in real time of any changes in the airFiberX radio’s IP settings. Even if the airFiberX radio’s IP address changes, you can still access the airFiberX radio through its domain name.Dynamic DNS If enabled, the airFiberX radio allows communications with the DDNS server.• Host Name Enter the host name of the DDNS server.• Username Enter the user name of the DDNS account.• Password Enter the password of the DDNS account.• Show Check the box to display the password characters.System LogSystem Log This option enables the registration routine of system log (syslog) messages. By default it is disabled.• Remote Log Enables the syslog remote sending function. System log messages are sent to a remote server, which is specified in the Remote Log IP Address and Remote Log Port fields. - Remote Log IP Address The host IP address that receives syslog messages. Properly configure the remote host to receive syslog protocol messages. - Remote Log Port The TCP/IP port that receives syslog messages. 514 is the default port for the commonly used system message logging utilities.Every logged message contains at least a system time and host name.
