Once a packet is classified, it is mapped to a forwarding queue. For all products except the SX-
F148GPP interface module and ICX 6430 switch, there are eight queues designated from 0 through 7.
The internal forwarding priority maps to one of these eight queues. For the SX-Fl48GPP interface
module and ICX 6430 switch, internal forwarding priority maps to four forwarding queues. The mapping
between the internal priority and the forwarding queue cannot be changed.
The following tables show the default QoS mappings for FCX platforms that are used if the trust level for
CoS or DSCP is enabled. For information on the SX-Fl48GPP interface module, refer to
on page 20. For information on default QoS mappings for the ICX 6430
switch, refer to
Queues for the ICX 6430 switch
on page 22.
