• VLAN P-Bit Re-Map – Why?
• Configuring the Re-Map Table
• Queuing without Re-Map
• Queuing with next classifier + Re-Map
• Queuing + Re-Map
• IP ToS over VLAN P-Bits
• VLAN P-Bits over IP ToS
• Using more than a single Classifier
Proprietary and Confidential
P-Bit Re-Map: Why?• Re-Map table is per port (e.g. every port can apply a different map)
• Can be used to re-scale Customer CoS
• Can be used to guaranty certain Customer priorities are reserved for specific purposes

Conditional Classification
Proprietary and Confidential
IP ToS over VLAN P-Bits
9
In case the ingress frame carries a VLAN and has an IP header - Classification is according to IP TOS
Otherwise the switch will apply the Default Configuration (Queue number).

Using more than a single Classifier

As long as the ingress frames comply to the higher conditions, the system will not check lower conditions (Classifiers)
If higher condition is not matched, the system will proceed to the lower condition and so on…

Audit VID : if VID = 100 than apply “High Service” otherwise - if VID = 200 than apply “Low Service”
Otherwise –
If ingress VID does not qualify (100 or 200)
then skip to -
