Example: Configuring Per-Unit Scheduling for Subscriber Access

In this example, a network administrator sets up a subscriber access configuration with per-unit scheduling.

1. The administrator configures the static VLAN interfaces and enables per-unit scheduling for the interfaces.
   [edit]interfaces {ge-1/1/0 {per-unit-scheduler;vlan-tagging;unit 100 {vlan-id 100;family inet {unnumbered-address lo0.0 preferred-source-address 192.100.1.1;}}unit 200 {vlan-id 200;family inet {unnumbered-address lo0.0 preferred-source-address 192.100.1.1;}}}ge-1/1/1 {per-unit-scheduler;vlan-tagging;unit 100 {vlan-id 100;family inet {unnumbered-address lo0.0 preferred-source-address 192.100.1.1;}}unit 200 {vlan-id 200;family inet {unnumbered-address lo0.0 preferred-source-address 192.100.1.1;}}}ge-1/0/1 {unit 0 {family inet {address 3.1.1.1/24;}}}ge-1/1/2 {description "wfce14 eth1 soso ge-1/1/2";vlan-tagging;gigether-options {no-auto-negotiation;}unit 100 {vlan-id 100;family inet {address 121.0.0.1/24;}}}}
2. The administrator configures static CoS parameters, including forwarding classes and classifiers, to be referenced in the dynamic profiles.
   [edit]class-of-service {classifiers {inet-precedence 8q-inet {forwarding-class be {loss-priority low code-points 000;}forwarding-class ef {loss-priority low code-points 001;}forwarding-class af {loss-priority low code-points 010;}forwarding-class nc {loss-priority low code-points 011;}forwarding-class voice {loss-priority low code-points 100;}forwarding-class video {loss-priority low code-points 101;}forwarding-class game {loss-priority low code-points 110;}forwarding-class data {loss-priority low code-points 111;}}inet-precedence 4q-inet {forwarding-class be {loss-priority low code-points [ 000 001 ];}forwarding-class ef {loss-priority low code-points [ 010 011 ];}forwarding-class af {loss-priority low code-points [ 100 101 ];}forwarding-class nc {loss-priority low code-points [ 110 111 ];}}inet-precedence 8q-drop-inet {forwarding-class be {loss-priority low code-points 000;}forwarding-class ef {loss-priority medium-low code-points 001;}forwarding-class af {loss-priority medium-high code-points 010;}forwarding-class nc {loss-priority high code-points 011;}forwarding-class voice {loss-priority low code-points 100;}forwarding-class video {loss-priority medium-low code-points 101;}forwarding-class game {loss-priority medium-high code-points 110;}forwarding-class data {loss-priority high code-points 111;}}inet-precedence 4q-drop-inet {forwarding-class be {loss-priority low code-points [ 000 001 ];}forwarding-class ef {loss-priority medium-low code-points [ 010 011 ];}forwarding-class af {loss-priority medium-high code-points [ 100 101 ];}forwarding-class nc {loss-priority high code-points [ 110 111 ];}}}drop-profiles {d0 {fill-level 25 drop-probability 100;fill-level 0 drop-probability 0;}d1 {fill-level 50 drop-probability 100;fill-level 0 drop-probability 0;}d2 {fill-level 75 drop-probability 100;fill-level 0 drop-probability 0;}d3 {fill-level 100 drop-probability 100;fill-level 0 drop-probability 0;}all {fill-level 0 drop-probability 0;fill-level 100 drop-probability 100;}}forwarding-classes {queue 0 be;queue 1 ef;queue 2 af;queue 3 nc;queue 4 voice;queue 5 video;queue 6 game;queue 7 data;}interfaces {ge-1/0/1 {unit 0 {classifiers {inet-precedence 8q-drop-low-high-inet;}}}}traceoptions {flag all;flag asynch;flag route-socket;}}
3. The administrator configures the access and service dynamic profiles to receive CoS parameters for the subscriber interfaces through RADIUS.
   [edit]dynamic-profiles {subscriber {interfaces {"$junos-interface-ifd-name" {unit "$junos-underlying-interface-unit" {family inet;}}}class-of-service {traffic-control-profiles {zero {scheduler-map

4. The network administrator configures DHCP and RADIUS to grant access and services to the interfaces referenced by the subscriber dynamic profile.
