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. 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.
