Brocade VCS Fabric QoS
Brocade VCS Fabric QoS requires very little user configuration. The only options to modify are the
fabric priority and the lossless priority.
Brocade VCS Fabric reserves a mapping priority and fabric priority of seven (7). Any traffic that
enters the Brocade VCS Fabric cluster from upstream that is using the reserved priority value is
automatically remapped to a lower priority.
Changing the mapping or fabric priority is not required. By default the values are set to zero (0) for
both of the re-mapped priorities.
In Brocade VCS Fabric mode:
• All incoming priority 7 tagged packets are dropped on the edge ports.
• Untagged control frames are counted in queue 7 (TC7).
All switches in the Brocade VCS Fabric cluster must have matching re-mapping priority values and
the same priority-group-table values.
