Table 20.1 – Traffic prioritization methods
Method
Description
0
All the priorities are equal
1
Packet selection according to IEEE 802.1p
2
Packet selection only according to IP ToS (Type of Service) on 3 level - support for Differentiated
Services Codepoint (DSCP)
3
Interaction according to either 802.1p or DSCP/TOS
Step 1.
Set a queue on which packets will be transmitted without preset rules. The 0 queue has the least
priority:
LTP-8X(switch)(config)# qos default 0
Step 2.
Set a traffic prioritization method by using
qos type
command. Send a type of prioritization as an
argument
LTP-8X(switch)(config)# qos type 1
Step 3.
Using
qos map
command, set rules for translation of 802.1p and DSCP/TOS to a queue number.
Send field type and priorities lists as parameters:
LTP-8X(switch)(config)# qos map 1 0-4,15,63 to 6
LTP-8X(switch)(config)# commit
LTP-8X(switch)(config)# exit
LTP-8X(switch)# show qos
Priority assignment by 802.1p packet field
Default priority queue is 0

20.3
Weighted Round Robin (WRR) configuration
Weighted Round Robin (WRR) – an algorithm which distribute throughput by classes, using a scheme of
weighted round robin. The OLT has 8 hardware queues.
Step 1.
Enable WRR and set 4 queues (0, 1, 2, 3) which will be processed by the algorithm. The other
queues will be strict. The WRR queues are enumerated from 0.
