QoS Configuration

Context

On the network where the voice VLAN function has been deployed, voice services have higher real-timeness than data services. Voice data must have a higher priority than other service data to minimize the delay during transmission. The 802.1p or DSCP priority of the voice VLAN is adjusted so that voice data is transmitted with a higher priority.

Enter that a VLAN has been configured on a switch interface through Interface Settings > Connect to IP Phone and the voice VLAN function has been enabled; otherwise, the QoS configuration is invalid.

Procedure

Choose Configuration > Advanced Services > Voice VLAN > QoS Configuration to access the QoS Configuration page.

Table 1 describes the parameters on the QoS Configuration page.
