QoS Configuration
DSCP tags set packet priorities for QoS.
DSCP Tag
DSCP (Differentiated Services Code Point) is a QoS mechanism for
setting relative priorities. Packets are tagged with a DSCP field in the
IP header for type of service. The decimal value may be set as a
number from 0-63 and may be different for each traffic class listed on
the screen.
• Administration tags set the priority for telnet, TFTP, and other
administrative traffic. Administrative traffic can have the lowest
priority because it does not require voice quality.
• WT (In call) traffic requires voice quality and may be set to a higher
priority than WT ( Standby ) traffic.
• RTP traffic is the audio traffic to the IP PBX. It requires voice
quality.
• PBX traffic is not audio to the PBX.
• Inter-SVP2 traffic is the information-passing protocol that SVP
Servers use to communicate with each other.
