QoS Function
QoS (Quality of Service) is the function to control the IP packet priority.
By configuring a DSCP (Differentiated Services Code Point) value for the packets to be sent by the repeater, the
packets including the packets to be sent by the repeater can be prioritized for a switch or router in the network.
When DSCP is enabled, a DSCP value is assigned as PHB (Per Hop Behavior) for the specified communication. This
allows packets to be queued and scheduled according to the priority configurations of the switches and routers
installed in the network, and can reduce loss such as a communication delay and jitter.

Note
 The VLAN tag in Layer2 is not supported.
 To use this function, all network devices such as routers and switches in the network need to support DSCP.
 Audio packets transmitted by a Console or SIP Phone cannot be prioritized by the repeater. To prioritize audio packets
transmitted by a Console or SIP Phone, configure according to each manufacturer's configuration method and recommended
DSCP value.
