Table 13: Summary of Differences Between Fabric fc-sets and Node Device
fc-sets
Node device fc-set Fabric fc-set Characteristic
QFabric system Node device. QFX3008-I or QFX3600-I
Interconnect device (the fabric). Location
Local to the Node device on
which the fc-set is configured. Global, valid for the entire fabric. Global or Node-device
specific
Yes. No. Use the 12 default fabric fc-sets
provided. Ability to create (define)
a new fc-set
User-configurable using traffic
control profiles. Default CoS settings only. CoS is not
user-configurable. Ability to configure CoS
Yes. Mapping is local to a Node
device and applies only to the
forwarding classes on the Node
device. Yes. Mapping is global and applies
to all forwarding classes across
Interconnect device fabric (traffic
from all connected Node devices). Ability to map
forwarding classes to an
fc-set
