FIGURE 2 Determining the trust level of a packet for ICX 7150 devices
Once a packet is classified, it is mapped to a forwarding queue. There are eight queues designated from 0 through 7. The internal
forwarding priority maps to one of these eight queues. The mapping between the internal priority and the forwarding queue cannot be
changed.
The following tables show the default QoS mappings for ICX platforms that are used if the trust level for CoS or DSCP is enabled.
