Creating a DSCP-to-CoS mutation map
You can use the incoming DSCP value of ingress packets to remap the outgoing 802.1P CoS priority
values by configuring a DSCP-to-CoS mutation map on the ingress interface. Perform the following
steps.
1. Issue the <edit-config> RPC to configure the <qos> node in the
urn:brocade.com:mgmt:brocade-qos namespace.
2. Under the <qos> node, include the <map> node element.
3. Under the <map> node, include the <dscp-cos> node element.
4. Under the <dscp-cos> node, include the following elements.
a. In the <dscp-cos-map-name> element, assign a name to the map.
b. A <mark> node element for each outgoing CoS priority value.
5. Under each <mark> node, include the following leaf elements.
a. In the <dscp-in-values> element, list the DSCP values to be mapped to a single CoS value.
b. In the <to> element, specify the CoS value.
6. Issue the <bna-config-cmd> RPC to save the running-config file to the startup-config file.
The following example creates a DSCP -to-CoS map named “test,” which performs the following
mapping of DSCP values to CoS priorities:
• DSCP values 1, 3, 5, and 7 are set to output as CoS priority 3.
• DSCP values 11, 13, 15, and 17 are set to output as CoS priority 5.
• DSCP values 12, 14, 16, and 18 are set to output as CoS priority 6.
• DSCP values 2, 4, 6, and 8 are set to output as CoS priority 7.
