JunosE 11.3.x Quality of Service Configuration Guide

Assured traffic is not strict, so it is scheduled by the HRR scheduler. Shape the assured
3.
traffic to 50 Mbps, and specify the hierarchical assured rate to give assured traffic
preferential treatment over best-effort traffic.
(config)#scheduler-profile assuredGroup
(config-scheduler-profile)#shaping-rate 50000000
(config-scheduler-profile)#assured-rate hierarchical
(config-scheduler-profile)#exit
Best effort traffic is also scheduled by the HRR scheduler. You do not apply any shaping
4.
for this traffic because it simply gets the leftover bandwidth.
(config)#scheduler-profile bestEffortGroup
(config-scheduler-profile)#exit
Create scheduler profiles for the voice, video, and best-effort service classes. Shape
5.
voice and video to 1 Mbps. Because you do not specify a shaping rate, the best-effort
traffic can borrow unused bandwidth.
(config)#scheduler-profile voice
(config-scheduler-profile)#shaping-rate 1000000
(config-scheduler-profile)#exit
(config)#scheduler-profile video
(config-scheduler-profile)#shaping-rate 1000000
(config-scheduler-profile)#exit
(config)#scheduler-profile best-effort
(config-scheduler-profile)#exit
Put the video traffic class into the assured-forwarding traffic-class group and specify
6.
the group as strict priority. Put the voice traffic class into the expedited-forwarding
traffic-class group. Put the best-effort traffic class into the best-effort traffic-class
group.
(config)#traffic-class-group assured-forwarding auto-strict-priority
(config-traffic-class-group)#traffic-class video
(config-traffic-class-group)#exit
(config)#traffic-class-group expedited-forwarding extended
(config-traffic-class-group)#traffic-class voice
(config-traffic-class-group)#exit
(config)#traffic-class-group best-effort extended
(config-traffic-class-group)#traffic-class best-effort
(config-traffic-class)#exit
Create a QoS profile that contains the group rules for the assured-forwarding,
7.
expedited-forwarding, and best-effort traffic-class groups.
