Chapter 12: Policer Overhead to Account for Rate Shaping in the Traffic Manager
To configure this example, perform the following tasks:
Configuring the Logical Interfaces on page 137
Configuring Traffic Rate-Shaping on the Logical Interface That Carries Output
Traffic on page 138
Configuring Policer Overhead on the PIC or DPC That Hosts the Rate-Shaped Logical
Interface on page 140
Applying a Policer to the Logical Interface That Carries Input Traffic on page 141
To quickly configure this example, copy the following configuration commands into a
text file, remove any line breaks, and then paste the commands into the CLI at the
hierarchy level.

Configuring the Logical Interfaces
To configure the logical interfaces:
Enable configuration of the interface
1.
[edit]
user@host# edit interfaces ge-1/3/1
Enable multiple queues for each logical interface (so that you can associate an
2.
output scheduler with each logical interface).
[edit interfaces ge-1/3/1]
user@host# set per-unit scheduler
