SonicOS 5.8.1 Administrator Guide
Note Mapping will not occur until you assign Map as an action of the QoS tab of an Access Rule.
The mapping table only defines the correspondence that will be employed by an Access
Rule’s Map action.
For example, according to the default table, an 802.1p tag with a value of 2 will be outbound
mapped to a DSCP value of 16, while a DSCP tag of 43 will be inbound mapped to an 802.1
value of 5.
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:
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.
