Switching between transfer speed and flow control automatic negotiation or manual setting.
MDIXMedia Dependent Interface Crossover enables working with both types of ethernet cables, straight-through and crossover. The default option “auto“ switches on automatic detection and performs an internal crossover if necessary.
Flow controlMechanism for temporarily stopping the transmission of data on an ethernet network. Enabling flow control allows use of buffers of connected active network elements for levelling uneven flow of user data. If flow control is enabled, you cannot use the built-in QoS functions. For correct operation it is necessary to also enable Flow control on the connected device.
MTUSetup of maximum allowed length of Ethernet frame. If transfer of tagged frames is not needed, you can choose smaller MTU. If you select smaller MTU, more storage space is available for QoS.
Internal VLAN idThe RAy unit uses one VLAN id for internal needs. It can be changed if there is a conflict with user data.

Storm control

Protection against packet flooding and subsequent device input switch blocking:

Broadcasttraffic directed to broadcast address (DA=FFFFFFFFFFFFH)
Multicasttraffic directed to multicast addresses (DA[40]=1B)
Un-learned unicastun-learned unicast traffic
100Mb/1Gb

Setting the threshold to activate protection. Set as number of packets per 50ms. Set separately for 10Mb link speed, or for 100Mb and 1Gb link speeds.

6.3.4. Settings – QoS

The Quality of Service (QoS) menu groups together multiple options of manipulating user data flow.

Ingress policing

Configuration menu Settings – QoS

Fig. 6.9: Configuration menu Settings – QoS

Ingress policing – causes user data flow to be limitted to certain value. The excessive packets are discarded.

Ingress policing

Enable Ingress policing. Applies to the device user port.

Speed [Mbps]

Data rate to limit the Ethernet traffic to. If this speed is exceeded, Flow control is initiated. If packets are still incoming, they are dropped.

Mode

Ingress policer operation mode:

  • soft – Flow control is activated at low fill of input buffer. Good to use if the connected device has Flow control enabled and has a large buffer.

  • default – Universal settings. Close to “hard” settings, but with Flow control enabled at connected device, packet loss is not possible.

  • hard – Flow control is activated only after the input buffer is completely full. Good to use if the connected device has a small buffer.

[Warning]Warning

The Ingress policing activation deactivates the switch QoS functions.

802.1p

Configuration menu Settings – QoS – 802.1p

Setup of QoS controlled by priority bits according to IEEE 802.1p.

802.1p

Enabling QoS according to 802.1p

Prefer DSCP

If priority control is enabled according to DSCP and incoming packet is coloured both by 802.1p priority and by DSCP – prioritization is governed (when enabling this option) by the DSCP rules.

Class of service 0..7

Arranging individual priorities (coded in priority bits according to IEEE 802.1p) into selected output queue (0..3).

[Warning]Warning

The QoS activation deactivates the Flow control and Ingress policing.

DSCP

Enabling QoS according to DSCP

DSCP 0..63

Arranging individual priorities (coded in DS field of IP header) into selected output queue (0..3).

[Warning]Warning

The QoS activation deactivates the Flow control and Ingress policing.

TCP/UDP ports

Configuration menu Settings – QoS – TCP/UDP ports

Fig. 6.12: Configuration menu Settings – QoS – TCP/UDP ports

Setting of QoS governed by number or range of TCP/UDP ports.

TCP/UDP ports

Enabling QoS according to TCP/UDP ports.

Prefer DSCP

If priority control is enabled according to DSCP and incoming packet is coloured both by DSCP priority and matches one of the rules listed here – prioritization is governed (with this option enabled) by the DSCP rules.

Stream 0..7

Up to 8 ranges of TCP/UDP ports can be configured. The range applies to both protocols: TCP and UDP.

  • From – Start of TCP/UDP ports range.

  • To – End of TCP/UDP ports range If we want to prioritize only one port, use same values for “From” and “To”. The range of TCP/UDP ports can be up to 255.

  • Side – Defines whether it is a source or destination TCP/UDP port(s).

  • Queue – The target output queue for packets matching the rule.

[Warning]Warning

The QoS activation deactivates the Flow control and Ingress policing.

Queue management

Configuration menu Settings – QoS – Queue management

Fig. 6.13: Configuration menu Settings – QoS – Queue management

Setting the operation mode of output queues. These are internal switch queues for organization of packets based on individual QoS rules.

[Note]Note

To enable configuring output queues, you must enable at least one of the QoS rules.

Mode

Regime for sending out packets from individual queues.

  • Strict – If there are packets in a high priority queue, packets from that queue are sent out. Only after this queue is completely empty, packets from a lower priority queue are sent out.

  • WFQ – Weighted Fair Queuing. Packets from individual queues are sent out according to set ratios (see below).

Ratio Mode

Turns on the WFQ regime sending out ratio.

Queue 0..3

Setting parameters (ratios) of packets sending out for individual queues.

  • Strict column – Maximum output speed [Mbps] for individual queues. Allowed range 0 .. 400 [Mbps]

  • WFQ Column – Packet sending out ratios for individual queues. Higher values means more frequent sending out from the given queue.

Smart discard

Setting mode for packet dropping in case of insufficient output channel capacity. Packets are dropped with certain probability before the queue is filled completely. For example, this mechanism prevents blocking of high priority packets by low priority packets. The “early random discard” mechanism is proving to be useful particularly for TCP traffic.

Smart discard mode can be used independently of QoS. To ensure correct function of Smart discard (i.e. Mode 1..3) Flow control is off.

Queue 0..3

Setting drop mode for individual output queues

  • Mode 0 (0/0) – Packets are dropped only after output queue is fully congested. Smart discard mode is therefore turned off.

  • Mode 1 (0/25) – When the queue is full to 3/4, packets will be dropped with 25% probability.

  • Mode 2 (25/50) – When the queue is full to 2/3, packets will be dropped with 25% probability. When the queue is full to 3/4, packets will be dropped with 50% probability.

  • Mode 3 (50/75) – When the queue is full to 2/3, packets will be dropped with 50% probability. When the queue is full to 3/4, packets will be dropped with 75% probability.

[Warning]Warning

The Smart discard mode activation deactivates the Flow control.

6.3.5. Settings – Service access

Services

Access routes for link configuration.

Configuration menu Settings – Service access – Services

Fig. 6.14: Configuration menu Settings – Service access – Services

IPv4 addressService IP address, by default 192.168.169.169 for L station and 192.168.169.170 for U station. Four addresses 169.254.173.236/30 are used for internal communication. Must not be used as service IP address.
Unknown IP addressFor easier identification of service IP address, RAy is equipped with LLDP protocol. Protocol sends a broadcast every 60 seconds with the following information:
  – IP address – under LLDP: Management address
  – Serial number – LLDP: System Description
  – Type (e.g. RAY17_L) – LLDP: Chassis Subtype
  – DATA_PORT for version with 1 eth or SERVICE_PORT for version with 2 eth – under LLDP: Port Subtype
Message can be recorded and converted into a readable form using a LLDP client. A suitable tool for this purpose is Wireshark IP traffic analysing tool, with free licenses available both for Windows and Linux. To locate the message easily, use the Capture filter “ether proto 0x88cc” in Wireshark.
NetmaskMask for service access, 24 by default.
GatewayDefault gateway for service access, empty by default.
HTTP(S)Allowing access via HTTP server (for HTTP and HTTPS protocol). Attention: after disabling access via HTTP server, you will not be able to access the unit using a web browser!
TelnetEnabling access via Telnet server. Provides access to CLI (Command Line Interface) for simple telnet clients. Disabled by default.
SSHEnabling access via SSH server. Provides secure access to CLI. If preventing unauthorized access to the station is number one priority, leave only this server on.
Management VLANEnabling access via VLAN management. Blocks access for https, ssh and telnet configuration via untagged packets (without VLAN) making only VLAN access possible. VLAN management is off by default. In case of RAy unit with two ports, VLAN management applies to the service port.
– ATTENTION-
By enabling VLAN management, ALL accesses are blocked for configuration using normal (untagged) LAN! During tests, you may enable VLAN management on one unit only. Then it is possible to access the link via LAN and VLAN either directly or via radio link.
Management VLAN idVLAN management id, by default 1. This field has to be filled out even when VLAN management is not active.
SNMPEnabling SNMP server. Off by default.
SNMP community stringSNMP community string. Can contain both lower and uppercase letters, numbers, four characters . : _ – and can be up to 256 characters long.

    Fig. 6.27: Configuration menu Tools – Maintenance – Firmware

    The sub-set of RAy parameters is affected by use of Feature keys.
    The feature keys limiting data transfer speed [Mbps] are now available. Speed of the transferred data is determined by a combination of the radio channel bandwidth (parameter Bandwidth [MHz]) and modulation order (parameter TX modulation). The Feature key limiting the data transfer speed enables only certain combinations of the channel bandwidth and modulation order to get the data transfer speed according to the Feature key. The data transfer speed is typically slightly higher than declared.
    When installed, the Feature key is activated after the station restart. The station can be restarted using the Tools-Maintenance-Restart menu. Choose the warm Restart mode.

    Local

    The active Feature keys in the Local station.
    FeatureName of the function controlled by the Feature key.
    LimitThe numeric value set by the key.
    RemoveThe specific Feature key can be deleted using the Delete button. The parameters controlled by this Feature key are reset to their default values after the station restart.
    Note: The link radio parameters can be changed subsequently (e.g. to a different operating frequency)!
    Upload local feature keysFeature keys are installed into the station from the binary files.
    Open file uploadDialog for the Feature key binary file selection is open.

    Peer

    Peer station active Feature keys. Feature keys of the Peer station are only displayed. They can be neither added, nor deleted. To be able to manipulate the Feature keys, it is necessary to access directly management interface of the relevant station – use the IP address of the relevant station.

    [Important]Important

    Applies only to links operating in the ISM band (RAy17, RAy24).

    Hardware of these links is universal for the entire frequency band. To facilitate the configuration of radio parameters, units are coded for L (Lower) and U (Upper) part of the band. L or U band assignment can be modified.

    Radio typeRadio unit type: L (Lower) or U (Upper) part of the frequency band.
    Use the Change button to change the radio type.

    Frequency tables

    The microwave link contains one or more frequency tables. These tables contain the following information:

    • List of available bandwidths and modulations.

    • Assignment of frequencies to the channels and the names of these channels. These channels are used to configure radio parameters of the link (see screen Settings-Radio).

    • Default values ​​of radio parameters.

    • A set of radio parameters, needed for the ATPC operation.

    ActiveName of the currently used frequency table.
    NewSelect a new frequency table. Use the Change button to change the table.
