4.2.6.6.3.2.2 IP Precedence Threshold
The IP Precedence Threshold parameter is applicable when the ToS Prioritization
Option is set to Enable IP Precedence (RFC791) Prioritization. If the value of the 3
IP Precedence bits in the IP header is higher than this threshold, the packet is
routed to the High queue. If the value is lower than or equal to this threshold, the
packet will be transferred to the Low queue (unless it is assigned a High priority
by another classifier).
Valid values range from 0 to 7.
The default value is 4.
4.2.6.6.3.2.3 DSCP Threshold
The DSCP Threshold parameter is applicable when the ToS Prioritization Option
is set to Enable DSCP (RFC2474) Prioritization. If the value of the 6 DSCP bits in
the IP header is higher than this threshold, the packet is routed to the High
queue. If the value is lower than or equal to this threshold, the packet will be
routed to the Low queue (unless it is assigned a High priority by another
classifier).
Valid values range from 0 to 63.
The default value is 32.
4.2.6.6.3.3 UDP/TCP Port Ranges Traffic Prioritization
The UDP/TCP Port Ranges Traffic Prioritization parameters enable defining
prioritization in accordance with the UDP and/or TCP destination port ranges.
The UDP/TCP Port Ranges Traffic Prioritization menu includes the following
parameters:
4.2.6.6.3.3.1 UDP/TCP Port Ranges Prioritization Option
The UDP/TCP Port Ranges Prioritization Option defines whether port ranges
based prioritization is enabled or disabled. The following options are available:
Disable
Enable Only for UDP
Enable Only for TCP
Enable for both UDP and TCP
The default is Disable.
