xConfiguration Network [1..1] QoS Mode
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.
Requires user role:
ADMIN
Value space:
<Off/Diffserv>
Off:
No QoS method is used.
Diffserv:
When you set the QoS Mode to Diffserv, the Network QoS Diffserv Audio, Network
QoS Diffserv Video, Network QoS Diffserv Data, Network QoS Diffserv Signalling, Network QoS
Diffserv ICMPv6 and Network QoS Diffserv NTP settings are used to prioritize packets.
Example:
xConfiguration Network 1 QoS Mode: Diffserv
xConfiguration Network [1..1] QoS Diffserv Audio
Note: This setting will only take effect if Network QoS Mode is set to Diffserv.
Define which priority Audio packets should have in the IP network.
The priority for the packets ranges from 0 to 63 - the higher the number, the higher the priority. The
recommended class for Audio is CS4, which equals the decimal value 32. If in doubt, contact your
network administrator.
The priority set here might be overridden when packets are leaving the network controlled by the
local network administrator.
Requires user role:
ADMIN
Value space:
<0..63>
Range:
Select a value between 0 to 63 - the higher the number, the higher the priority. The default
value is 0 (best effort).
Example:
xConfiguration Network 1 QoS Diffserv Audio: 0
xConfiguration Network [1..1] QoS Diffserv Video
Note: This setting will only take effect if Network QoS Mode is set to Diffserv.
Define which priority Video packets should have in the IP network. The packets on the presentation
channel (shared content) are also in the Video packet category.
The priority for the packets ranges from 0 to 63 - the higher the number, the higher the priority. The
recommended class for Video is CS4, which equals the decimal value 32. If in doubt, contact your
network administrator.
The priority set here might be overridden when packets are leaving the network controlled by the
local network administrator.
Requires user role:
ADMIN
Value space:
<0..63>
Range:
Select a value between 0 to 63 - the higher the number, the higher the priority. The default
value is 0 (best effort).
Example:
xConfiguration Network 1 QoS Diffserv Video: 0
xConfiguration Network [1..1] QoS Diffserv Data
Note: This setting will only take effect if Network QoS Mode is set to Diffserv.
Define which priority Data packets should have in the IP network.
The priority for the packets ranges from 0 to 63 - the higher the number, the higher the priority.
The recommended value for Data is 0, which means best effort. If in doubt, contact your network
administrator.
The priority set here might be overridden when packets are leaving the network controlled by the
local network administrator.
Requires user role:
ADMIN
Value space:
<0..63>
Range:
Select a value between 0 to 63 - the higher the number, the higher the priority. The default
value is 0 (best effort).
Example:
xConfiguration Network 1 QoS Diffserv Data: 0
