You are allowed to override these default traffic class mappings per port. Once the traffic class

Multicast traffic
Fabric OS v6.3.1_cee supports four multicast traffic classes for isolation and to control servicing for
different priorities of application data. Traffic classes are numbered from 0 through 7, with higher
values designating higher priority. The traffic class mapping stage provides some flexibility in queue
selection.
