Table 3.46 - Ieee 802.1P Classification; Table 3.47 - Diffserv Classification - Alcatel-Lucent 9500 User Manual

For each egress port according to method of QoS classification configured in the switch,
the packets are assigned to each queue.
3.10.13.1.1 — TDM flows classification
All the TDM traffic flows will be assigned to the highest egress priority queue (Q4).
3.10.13.1.2 — Ethernet flows classification
For generic Ethernet flows in the switch the priority of each packet can be assigned
according to the information in:
• IEEE 802.1p: the packet is examined for the presence of a valid 802.1P user-priority
tag. If the tag is present the correspondent priority is assigned to the packet
• DiffServ: each packet is classified based on DSCP field in the IP header to determine
the priority.
3.10.13.1.3 — Scheduler
The scheduler algorithm cannot be configured. HQP scheduler algorithm is used on queue
Q4.
