Classification
15
Once a packet is classified by one of the procedures mentioned, it is mapped to an internal
forwarding queue. There are eight queues designated as 0 to 7. The internal forwarding priority
maps to one of these eight queues as shown in Table 58 through Table 61. The mapping between
the internal priority and the forwarding queue cannot be changed.
Table 58 through Table 61 show the default QoS mappings that are used if the trust level for CoS or
DSCP is enabled.
