Firewall > QoS Mapping Each of these mappings can be reconfigured. If you wanted to change the outbound mapping of 802.1p tag 4 from its default DSCP value of 32 to a DSCP value of 43, you can click the Configure icon for 4 – Controlled load and select the new To DSCP value from the drop-down box: 802.1p CoS 1 end-range remap 802.1p CoS 2 start-range remap You can restore the default mappings by clicking the Reset QoS Settings button. Managing QoS Marking QoS marking is configured from the QoS tab of Access Rules under the Firewall > Access Rules page of the management interface. Both 802.1p and DSCP marking as managed by SonicOS Enhanced Access Rules provide 4 actions: None, Preserve, Explicit, and Map. The default action for DSCP is Preserve and the default action for 802.1p is None. The following table describes the behavior of each action on both methods of marking: Action 802.1p (layer 2 CoS) DSCP (layer 3) Notes None The DSCP tag is explicitly set (or When packets matching this class of reset) to 0. traffic (as defined by the Access Rule) are sent out the egress interface, no 802.1p tag will be added. If the target interface for this class of traffic is a VLAN sub-interface, the 802.1p portion of the 802.1q tag will be explicitly set to 0. If this class of traffic is destined for a VLAN and is using 802.1p for prioritization, a specific Access Rule using the Preserve, Explicit, or Map action should be defined for this class of traffic. Preserve Existing 802.1p tag will be preserved. 476 Existing DSCP tag value will be preserved. SonicOS Enhanced 4.0 Administrator Guide
