Setting QoS Parameters

Procedure

1. Choose System Settings > Network and click the QoS tab.
2. Set the QoS parameters listed in Table 3-30.
   Table 3-30  QoS parameters

   Parameter	Description	Setting
   QoS type	Specifies the type of the Quality of Service (QoS) network security measure used to deal with the network latency, congestion, and other issues. Priority: If you select this option, you must also set IP priority and Service type. DiffServ: If you select this option, you must also set DSCP.	The default value is Priority.
   IP priority	Specifies the priority that a network device gives to forwarding the data packets sent by your endpoint. A larger value indicates a higher priority.	The default value is 5. Value range: 0-7
   Service type	Specifies how the data packets sent and received by your endpoint are processed on the network. Normal: Network devices transmit the data packets without special processing. Minimum delay: Data packets are transmitted at the highest rate with the minimum delay. Maximum throughput: A large amount of data packets can be transmitted on the network. Highest reliability: Data packets can be transmitted to remote sites completely and correctly. Minimum cost: Network devices transmit data packets of the same traffic at lower costs.	The default value is Minimum delay.
   DSCP video DSCP audio DSCP signaling DSCP data	Specify the service level of data packets sent by your endpoint during transmission. A larger value indicates a higher service level.	The default value is 32. Value range: 0-63
   Network jitter	Adjusts network jitter settings to address: Labial synchronization problems during conferences Choppy audio problems, by increasing the network jitter value.	The default value is 0ms. Value range: 0 ms to 1000 ms
   Lip sync.	Fine-tunes network jitter settings if a slight labial synchronization problem persists after the network jitter settings are adjusted.	The default value is 0ms. Value range: 0 ms to 300 ms
