Quanta 70: Installation and Configuration

Quanta 70 web interface is an intuitive and responsive user interface adjusts the layout based on the size of your screen. Automatic mechanisms such as auto-channel and automatic transmit power control optimize the link for maximum performance in interference free band.

1. Access to the device

Network Settings

By default wireless device has IP address 10.10.10.1 with 255.255.255.0 network mask. The workstation used to perform initial configuration must have an IP address from the same subnet.

Login and Password

By default no login or password are set, use any letters or numbers for initial authentication.

Web Interface

Navigation in the web interface is performed using the side menu, which includes the following sections:

• Dashboard.
• Settings.
• Service.

Dashboard

This section displays the information on the wired and wireless connections state updated in real time and statistics since the last reboot. For detailed description of the parameters proceed to the "9. Diagnostics" lesson.

2. Applying changes

To make changes in the device configuration click the "Changes" button in the upper right corner of the web interface.

The "Applying global changes" window contains a table of parameters whose values have been changed by the user. If you want to undo one change, click the "Roll back" button near the entry. If you need to undo all changes, use the "Roll back" button at the bottom of the window. Changes will be saved to the device configuration by clicking the "Apply" button.

To apply the configuration safely, use the "Try" button. In this case, the previous configuration will be restored after 180 seconds automatically if changes will not be confirmed or test period extended by the administrator.

3. Settings

General

The section is designed to configure the basic system parameters of the device.

Unit

Configure the device name for easy identification. Can be an arbitrary set of characters. Is used for easy device identification by the network administrator, is displayed in the web interface in the "Dashboard" section.

The section is designed to configure the basic system parameters of the device.

SNTP

SNTP Server Address - the SNTP server IP address, the SNTP service will synchronize the time on the device with. The device must have network access to the SNTP server.

Time Zone - the time zone at the place of device installation. For example: GMT + 5.

Security

This section allows to configure device access and security settings.

Administrator access - here you may change system administrator account login and password, to change the identification data, click the "Change admin password" button. We strongly recommend you to set a login and password after the first login to the device.

Radius AAA - here you may configure a device access control using a remote RADIUS server.

• Address - set the RADIUS server IP address.
• Port - set the RADIUS server port.
• Secret - set the server password.

Command line interface:

• Allows to enable / disable remote device control by the command line using Telnet and SSH protocols.
• SSH (Secure Shell) protocol provides secure remote control to network devices. Its functionality is similar to the Telnet protocol, but, unlike Telnet, SSH encodes all protocol messages, including transmitted passwords. By default, only access via Telnet is enabled.

Network access - this section is used to create a list of subnets from which access to the device will be allowed.

Radio authentication settings - units at both ends of the wireless link should authorize each other before link establishment. Access key must be up to 64 characters long, without spaces and must be the same at both ends of the link.

Radio

The section includes the radio subsystem parameters necessary for wireless link establishing.
 

Radio frontend:

• Unit role - one of the devices must be "Master", the second - "Slave". Please note that the center frequency must be equal for "master" and "slave" unit to establish the radio link. When a wireless link has been established Slave unit will continuously inherit radio frontend parameters from Master unit excluding frequency channel grid. So, if you change some values on Master they will be set on Slave automatically.
• Center frequency - should be selected manually in accordance with the actual frequency grid. The Quanta 70 accepts values i range 70500-76000.
• Power limit - two ways of power limiting are available:
  • Transmitter power output - limits transmitter power to a specified value.
  • EIRP - limits the overall system transmitted power, calculated by the formula: transmitter power + antenna gain (should be set in the field below).

Air frame:

• Frame length:
  • The greater frame length the more payload will be transmitted in one frame. Greater values increase latency.
  • The lower frame length the less payload will be transmitted in one frame. Lower values decrease latency.
  • Available values: 0.1; 0.2; 0.5 ;1; 2; 5 ms.
• Downlink/Uplink ratio - available only on Master unit. In automatic mode, the ratio changes dynamically in accordance with the transmitted traffic. Manual mode allows to set a fixed value using the slider. Available values depend from frame length.

Automatic modulation and transmit power control:

• AMC strategy - allows to select a strategy of modulation switching for cases when the transmission medium conditions change. The following strategies are available:
  • Normal - keeps balance between the number of errors and bandwidth.
  • Conservative - assumes using higher CINR thresholds in order to minimize the error rate.
  • Aggressive - lowers the thresholds in order to use higher modulation levels and thus increase the throughput.
  • Extreme - lowers the CINR threshold below the Aggressive strategy values in order to maximize selected modulation and throughput.
• Automatic transmit power control - controls transmitter output power automatically based on target RSSI value. If actual RSSI level is lower then unit increases transmitter output power of the remote unit and vice versa. ATPC could not set value that may exceed the "Power limit" value.
• Target RSSI - RSSI value which will be used by ATPC as target.

Frequency channel grid - the frequency grid allows to limit the frequency range available to use. Values can be set as a range (70500-72500) or as a list (71500, 73400, 75600) with the step from 0,125 MHz till 10000 MHz.

Network

This section allows to assign an IP address or several addresses to the wired interface, the default gateway value can also be specified.

Click the "Add IP address" button to add a new address. There are two ways to assign an IP address:

• Automatically - the IP address will be obtained automatically from the DHCP server.
• Manual - the IP address and netmask are specified manually.

The VLAN tag value can also be set in this section, the VLAN ID value should be in range from 1 to 4096.

Switch

Network ports - each Quanta 70 family device has 3 interface:

• ge0 - combo port, depends on physical connection type can be Gigabit Ethernet 1000BASE-T or SFP Port 1000BASE-X (to specify the connection type see "Wired interface" section on the Dashboard). Only ge0 interface is available to configure. The following parameters can be changed:
  • Status: enabled/disabled.
  • Duplex: duplex mode, "auto" is by default.
  • Description: arbitrary text description.
• radio - internal radio interface;
• mgmt - internal interface for device management.

QoS - enable/disable prioritization strategy. Unit will recognize the 802.1p tags in Ethernet frame headers. Based on these tags priorities will be autlomatically assigned to the frames when they are sent over the radio interface. After transmission over radio interface frames with tags are sent to Ethernet. Priorities may be adjusted manually if a VLAN based switching is enabled.

VLAN based switching - allows to create list of allowed VLANs and their handling on the unit switch plane. If VLAN based switching is enabled but no VLANs are added, device ports will allow untagged traffic only. Each entry of list establishes the relationship between VLAN ID and ports VLAN modes.

VLAN ID -VLAN tag in range from 1 to 4095. May be set in a few ways, examples:

• 12
• 10-20
• 100,200,300
• 23,24,25,50-100

Description - arbitrary text description.
 

Priority - allows to set the priority of a specific VLAN according to 802.1p ranging from 0 to 7, where 0 - the lowest priority level, 7 - the highest.

• Connectivity matrix - allows to configure the traffic transfer between the network ports of the device. Configuration is performed visually using switches. The green switch indicates allowed connections, the red one - denied:
  • ge0 - wired port.
  • radio - internal radio interface;
  • mgmt - internal interface for device management.

Traffic flow between ports is performed in accordance with VLAN modes set, if the VLAN based switching is enabled.

SNMP

SNMP allows the administrator to gather information about key device parameters and wireless links, including information about changes. The use of any monitoring system helps to timely receive information about the network infrastructure state using Infinet devices. Currently, the Quanta 70 devices families support SNMP protocol versions v1 v2c and v3.

The SNMP Protocol has two branches, the agent and the management stations:

• The agent sends data to the management station. Monitoring system - provides data gathering from all agents in the network.
• The monitoring system receives and processes events.
• The information is passed through requests and replies with the use of the MIB.
• The management station or monitoring system is responsible for decoding the SNMP packets and providing an interface to the administrator.

General settings

This section allows to enable/disable SNMP protocol support.

To make the device identifying easier, enter the data of Contact person performing the maintenance. The physical location of the device can also be specified in an arbitrary format, the line length should not exceed 20 characters.

SNMP v1/v2c

This section allows to enable/disable the SNMP v.1 and v.2c support. The first version of the SNMP protocol lacks security, that hinders its use for network management, so SNMP v.1 and v.2c operates in read-only mode. Enabled by default.

Set the Community name for read-only mode of SNMP v.1 and v.2c, by default: "public". The community name passes along with the data packet in clear text.

Due to the security level of SNMP v.3 is higher than of SNMP v.1 and v.2c, it allows not only the data collection but also to manage devices. Detailed information about the devices management via the monitoring system is available in the corresponding article of the technical documentation.

Add SNMP v3 User. In the appeared window, enter the User Name, select the required Security level:

• "No auth / No privacy" – the lowest security level without authentication and privacy, only User Name needs to be set. This level of protection does not allow management via the monitoring system.
• "Auth / No privacy" – middle level with authentication but without privacy, User Name and Password are required.
• "Auth / Privacy" – highest level with authentication and privacy, User Name, Password, Privacy Password and Privacy Protocol should be set.

Configure permissions for this entry. To collect data without the possibility of making changes, activate the Read Only mode, to implement all management possibilities, activate the Admin mode.

SNMP traps

The devices polling cycle of the monitoring system is 5 minutes. To speed up the process of detecting incidents on devices, SNMP traps can be send each time an incident occurs, regardless of the polling process.

Enable SNMP traps by activating the corresponding flag. Set the source IP address to help the monitoring system to identify the device. Create a new entry by clicking the "Add SNMP Trap" button.

In the appeared window, set the destination IP address, for example, the monitoring system, and UDP port (usually 162 is used). Activate the checkboxes opposite the groups of traps that should be sent by the device.
