Configuring a Hard PVC for Structured CES with a Shaped VP Tunnel

A shaped VP tunnel is a VP tunnel that, by default, carries only VCs of the constant bit rate (CBR)
service category with a peak cell rate (PCR). However, it is possible to configure a shaped virtual path
(VP) tunnel to carry VCs of other service categories. The overall output of the shaped VP tunnel is
rate-limited, by hardware, to the PCR of the tunnel.
This section describes how to configure a hard PVC for structured CES with a shaped VP tunnel, which
is a two-phase process, as follows:
