Table 8: Default Fabric Forwarding Class Sets (continued)
Characteristics Fabric Forwarding Class Set Name
(Hidden) No traffic is assigned by default to this fabric
fc-set. Unless traffic is mapped to this fabric fc-set, this
fabric fc-set remains hidden. This fabric fc-set is valid
only for lossless forwarding classes. fabric_fcset_noloss6
Transports multidestination traffic in the
mcast
forwarding class across the fabric. This fabric fc-set is
valid only for multidestination forwarding classes.
fabric_fcset_multicast1
(Hidden) No traffic is assigned by default to this fabric
fc-set. Unless traffic is mapped to this fabric fc-set, this
fabric fc-set remains hidden. This fabric fc-set is valid
only for multidestination forwarding classes.
fabric_fcset_multicast2
(Hidden) No traffic is assigned by default to this fabric
fc-set. Unless traffic is mapped to this fabric fc-set, this
fabric fc-set remains hidden. This fabric fc-set is valid
only for multidestination forwarding classes. fabric_fcset_multicast3
(Hidden) No traffic is assigned by default to this fabric
fc-set. Unless traffic is mapped to this fabric fc-set, this
fabric fc-set remains hidden. This fabric fc-set is valid
only for multidestination forwarding classes. fabric_fcset_multicast4
The five default forwarding classes ( best-effort , fcoe , no-loss , network-control , and mcast )
are mapped to the fabric fc-sets by default as shown in Table 9 on page 65 .
