Description (or Subfield and Description)
A descriptive name of the QoS profile for identification and management purposes.
Select the Re-Mark check box to set the differentiated services (DiffServ) mark in
the Type of Service (ToS) byte of an IP header by specifying the QoS type (IP
precedence or DHCP) and QoS value. If you clear the Re-Mark check box (which
is the default setting), the QoS profile is specified only by the QoS priority.
QoS (Type)
From the QoS drop-down list, select one of the following traffic
classification methods:
• IP Precedence. A legacy method that sets the priority in the ToS
byte of an IP header.
• DSCP. A method that sets the Differentiated Services Code Point
(DSCP) in the Differentiated Services (DS) field (which is the
same as the ToS byte) of an IP header.
QoS Value
The QoS value in the ToS or Diffserv byte of an IP header. The QoS
value that you enter depends on your selection from the QoS drop-
down list:
• For IP Precedence, select a value from 0 to 7.
• For DSCP, select a value from 0 to 63.
The QoS priority represents the classification level of the packet among the priority
queues within the VPN firewall. If you select Default, packets are mapped based
on the ToS bits in their IP headers.
From the QoS Priority drop-down list, select one of the following priority queues:
• Default
• High
• Medium High
• Medium
• Low
