ProSafe Gigabit Quad WAN SSL VPN Firewall SRX5308 Reference Manual Note: This document assumes that you are familiar with QoS concepts such QoS priority queues, IP precedence, DHCP, and their values. Table 4-7. QoS Profile Settings Setting Description (or Subfield and Description) Profile Name A descriptive name of the QoS profile for identification and management purposes. Re-Mark 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 Priority 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 dropdown 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 5. Click Apply to save your settings. The new QoS profile is added to the List of QoS Profiles table. To edit a QoS profile: 1. In the List of QoS Profiles table, click the Edit table button to the right of the QoS profile that you want to edit. The Edit QoS Profile screen displays. 4-36 v1.0, April 2010 Firewall Protection
