TX and RX channels are selected from a
list of channels. The basic configuration has the TX and RX
options interconnected. In this case the basic duplex spacing
between channels is preserved and by selecting one channel,
the other three are defined as well. For stations operating in
free bands, it is possible to disconnect the TX-RX lock and
select TX and RX channels individually. Corresponding channels
at peer station are set automatically. Notice – Non-standard duplex setting leads to non-effective use of the spectrum. | |

Ethernet interface physical layer parameters setup.
Switching between transfer speed and flow control automatic negotiation or manual setting. | |
Media 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. | |
Mechanism 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. | |
Setup 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. | |
The RAy unit uses one VLAN id for internal needs. It can be changed if there is a conflict with user data. |
Protection against packet flooding and subsequent device input switch blocking:
traffic directed to broadcast address (DA=FFFFFFFFFFFFH) | |
traffic directed to multicast addresses (DA[40]=1B) | |
un-learned unicast traffic | |
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. |
The Quality of Service (QoS) menu groups together multiple options of manipulating user data flow.
Ingress policing – causes user data flow to be limitted to certain value. The excessive packets are discarded.
Enable Ingress policing. Applies to the device user port. | |
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. | |

Setting of QoS governed by number or range of TCP/UDP ports.
Enabling QoS according to TCP/UDP ports. | |
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. | |
Up to 8 ranges of TCP/UDP ports can be configured. The range applies to both protocols: TCP and UDP.
|
Warning | |
---|---|
The QoS activation deactivates the Flow control and Ingress policing. |
Setting the operation mode of output queues. These are internal switch queues for organization of packets based on individual QoS rules.
Note | |
---|---|
To enable configuring output queues, you must enable at least one of the QoS rules. |
Regime for sending out packets from individual queues.
| |
Turns on the WFQ regime sending out ratio. | |
Setting parameters (ratios) of packets sending out for individual queues.
|
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.

To facilitate communication with the technical support you can create an archive file with detailed information about the station. If connection with Peer station is functional, information from both stations is saved.
Saving a file with information about the station (Local and Peer). 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
