Network [1..1] IPv4 QoS Mode
Defines whether IP Diffserv QoS should be used. The QoS (Quality of Service) is a method which
handles the priority of audio, video and data in the network. The QoS settings must be supported by the
infrastructure. DiffServ (Differentiated Services) is a computer networking architecture that specifies a
simple, scalable and coarse-grained mechanism for classifying, managing network traffic and providing
QoS priorities on modern IP networks.
Valuespace: <Off/Diffserv>
Off: When set to Off no QoS method is used.
Diffserv: Select Diffserv and then go to the Diffserv sub-menus (Audio, Data, Signalling and Video) to
configure these settings.
Example: Network 1 IPv4 QoS Mode: diffserv
Network [1..1] IPv4 QoS Diffserv Audio
The DiffServ Audio setting is used to define which priority Audio packets should have in an IP network.
Enter a priority, which ranges from 0 to 63 for the packets. The higher the number, the higher the priority.
These priorities might be overridden when packets are leaving the network controlled by the local network
administrator.
Valuespace: <0..63>
Audio: A recommended value is DiffServ Code Point (DSCP) is AF41, which equals the value 34. If in
doubt, contact your network administrator.
Range: 0-63
Example: Network 1 IPv4 QoS Diffserv Audio: 0
Network [1..1] IPv4 QoS Diffserv Data
The DiffServ Data setting is used to define which priority Data packets should have in an IP network.
Enter a priority, which ranges from 0 to 63 for the packets. The higher the number, the higher the priority.
These priorities might be overridden when packets are leaving the network controlled by the local network
administrator.
Valuespace: <0..63>
Data: A recommended value is DiffServ Code Point (DSCP) AF23, which equals the value 22. If in
doubt, contact your network administrator.
Range: 0-63
Example: Network 1 IPv4 QoS Diffserv Data: 0
Network [1..1] IPv4 QoS Diffserv Signalling
The DiffServ Signalling setting is used to define which priority Signalling packets should have in an IP
network. Enter a priority, which ranges from 0 to 63 for the packets. The higher the number, the higher the
priority. These priorities might be overridden when packets are leaving the network controlled by the local
network administrator.
Valuespace: <0..63>
Signalling: A recommended value is DiffServ Code Point (DSCP) AF31 which equals the value 26. If in
doubt, contact your network administrator.
Range: 0-63
Example: Network 1 IPv4 QoS Diffserv Signalling: 0
Network [1..1] IPv4 QoS Diffserv Video
The DiffServ Video setting is used to define which priority Video packets should have in an IP network.
Enter a priority, which ranges from 0 to 63 for the packets. The higher the number, the higher the priority.
These priorities might be overridden when packets are leaving the network controlled by the local network
administrator.
Valuespace: <0..63>
Video: A recommended value is DiffServ Code Point (DSCP) AF41, which equals the value 34. If in
doubt, contact your network administrator.
Range: 0-63
Example: Network 1 IPv4 QoS Diffserv Video: 0
Network [1..1] MTU
Set the ethernet MTU (Maximum Transmission Unit).
Valuespace: <400..1500>
Range: 400-1500
Example: Network 1 MTU: 1500
