In the previous example, the ClassAF1 does not classify traffic as intended. Traffic matching the first
match criteria is classified to Queue 1, but all other traffic is classified to Queue 0 as a result of CAM entry
20419.
When you remove the explicit "deny any" rule from all three ACLs, the CAM reflects exactly the desired
classification.
The following example shows correct traffic classifications.

Dot1p to Queue Mapping Requirement

The dot1p to queue mapping on the system is global and this is used to configure the PRIO2COS table
configuration. For DSCP based PFC feature on untagged packets, this mapping must be the same as the
default dot1p to queue mapping and should not be changed (as in TABLE 1). If a custom dot1p to queue
mapping is present it should be reconfigured to the default dot1p to queue mapping.
• Currently Dell Networking OS supports matching only the following TCP flags:
– ACK
– FIN
– SYN
– PSH
– RST
– URG
In the existing software, ECE/CWR TCP flag qualifiers are not supported.
• Because this functionality forcibly marks all the packets matching the specific match criteria as
'yellow', Dell Networking OS does not support Policer based coloring and this feature concurrently.
• If single rate two color policer is configured along with this feature, then by default all packets less
than PIR would be considered as "Green" But 'Green' packets matching the specific match criteria for
which 'color-marking' is configured will be over-written and marked as "Yellow".
