Table 26 Default User Priority For Multicast Traffic Class Mapping - Brocade Communications Systems Converged Enhanced Ethernet 8000 Administrator's Manual

Queueing
Multicast traffic
Fabric OS v7.0.0supports four multicast traffic classes for isolation and to control servicing for
different priorities of application data. Traffic classes are numbered from 0 through 3, with higher
values designating higher priority. The traffic class mapping stage provides some flexibility in queue
selection.

Once the traffic class mapping has been resolved for ingress traffic, it is applied consistently
across all queueing incurred on the ingress and egress ports.
Mapping CoS-to-Traffic-Class
To map a CoS-to-Traffic-Class, perform the following steps from privileged EXEC mode.
1. Enter global configuration mode.
2. Create the CoS-Traffic-Class mapping by specifying a name and the mapping.
3. Enter the copy command to save the running-config file to the startup-config file.
Activating a mapping CoS-to-Traffic-Class
To activate a CoS-to-traffic class mapping, perform the following steps from privileged EXEC mode.
1. Enter global configuration mode.
2. Specify the 10-gigabit Ethernet interface.
3. Activate the CoS-to-Traffic-Class mapping by name.
