Example: Configuring Shared Resources on Ethernet IQ2 Interfaces
For input traffic on physical interface ge-1/2/3,
logical interface units 1, 2, and 3 are sharing one set of scheduler-shaper resources, defined by traffic-control
profile s1. Logical interface units 4, 5, and 6 are sharing another set of scheduler-shaper
resources, defined by traffic-control profile s1.
For output traffic on physical interface ge-1/2/3, logical interface units 1, 2, and 3 are sharing one set of scheduler-shaper resources, defined by traffic-control
profile s2. Logical interface units 4, 5, and 6 are sharing another set scheduler-shaper
resources, defined by traffic-control profile s2.
For each physical interface, the shared-instance statement
creates one set of resources to be shared among units 1, 2, and 3 and another set of resources to
be shared among units 4, 5, and 6. Input and output shaping rates are configured at the physical interface
level, which demonstrates the hierarchical shaping capability of the
Gigabit Ethernet IQ2 PIC.

Configuring a Simple Filter
Configure a simple filter that overrides the classification derived from the lookup of the Layer 2 fields.
