5. Type a name for the CEE map in the Name field.
6. Type a precedence value in the Precedence field. The value is specified as a number. The
allowable range is 0 to 100. The default is 1.
The precedence value controls QoS scheduling policies. If different CEE maps have conflicting
policies, the scheduler gives precedence to the CEE map with the highest precedence value
(the highest number).
When the CEE Map Configuration dialog box is displayed, the default values shown in the
Priority Group Map match the IEEE 802.1Q recommendation for systems supporting eight
traffic classes. The Priority Group Map shows the Layer 2 CoS values mapped to Priority Group
IDs (PGID). PGID values are in the form
<policy>.<priority>. A policy value of 15 indicates
Priority values run from 0 (highest priority) to 7 (lowest priority). Note that this is contrary to the
CoS values, which run from 7 (highest priority) to 0 (lowest priority).
7. Create a new priority group by clicking Add next to the Priority Group table.
