Configuration Examples for Traffic Shaping
This section provides the following sample configurations for traffic shaping:
• Configuration Example for Class-Based Shaping, page 9-21
• Configuration Examples for Hierarchical Shaping, page 9-21
Configuration Example for Class-Based Shaping
Example 9-6 defines one class named c1, which is configured to shape traffic to 384 kbps with a normal
burst size of 15,440 bits.
Example 9-6 Configuring Class-Based Shaping

Note The shape average command is available only on the PRE3. The PRE2 supports the shape cir command.
Configuration Examples for Hierarchical Shaping
Example 9-7 shows how to configure hierarchical shaping. In this example, the total VC bandwidth (the
sum of SCR) is above the tunnel rate. The PVP is configured with a PCR of 1000 kbps and is
oversubscribed by the total rate of the VCs (2 VCs at 256
kbps and 2 VCs at 512 kbps). The queue-depth
command ensures the correct shaping.
