NOTE: This example includes both MPLS and policy configuration commands, and
assumes that you are thoroughly familiar with the information and commands
presented in the
JUNOSe Policy Management Configuration Guide .
The four traffic classes are configured to allocate fabric resources and allow global
synchronization of the three segments of the data path through an E Series router:
ingress, fabric, and egress. The JUNOSe software automatically creates the best-effort
traffic class, with a default weight of eight. You must define the remaining three
classes, af1, af2, and ef. In this example, the af1 class has twice as much fabric
bandwidth as the best-effort class, and the af2 class has twice as much fabric
bandwidth as the af1 class. The expedited forwarding traffic (the ef class) requires
strict-priority queuing.
host1(config)# traffic-class af1
host1(config-traffic-class)# fabric-weight 16
host1(config)# traffic-class af2
host1(config-traffic-class)# fabric-weight 32
host1(config)# traffic-class ef
host1(config-traffic-class)# fabric-strict-priority
Define two scheduler profiles for the af1 and af2 classes on the egress line modules:
host1(config)# scheduler-profile af1-scheduler-profile
host1(config-scheduler-profile)# weight 16
host1(config)# scheduler-profile af2-scheduler-profile
host1(config-scheduler-profile)# weight 32
Create queue profiles to define how queues are instantiated to implement the
corresponding traffic classes and PHBs. The JUNOSe software automatically creates
the best-effort queue profiles.
host1(config)# queue-profile af1-queues
