Configuring the DSCP trust mode
Like QoS trust mode, the Differentiated Services Code Point (DSCP) trust mode controls the
user-priority mapping of incoming traffic. The user priority is based on the incoming DSCP value.
When this feature is not enabled, DSCP values in the packet are ignored.
When DSCP trust is enabled, Table 13 shows default mapping of DSCP values to user priority.
To configure DCSP trust mode, perform the following steps.
1. Issue the RPC to configure the node in the
urn:brocade.com:mgmt:brocade-interface namespace.
2. Under the node, include the , ,
, , or node element.
3. Under the , , ,
, or node, include the element and set its
value to the name of the interface for which you want to configure QoS trust mode.
4. Under the , , ,
, or node, include the element located in the
urn:brocade.com:mgmt:brocade-qos namespace.
5. Under the node, include the / element hierarchy to set the interface
mode to DSCP “trust”.
