Configuration Example for Configuring a Hierarchical Policy and PVC-Based FRF.12 Fragmentation
Example 16-13
In the example, access control lists (ACLs) 101 and 102 are defined and used as match criteria in two
class maps to classify traffic. The child policy map named qos_pq_cbwfq_0 defines the traffic class
named acl_101 as priority traffic and polices the traffic at 10 percent of the parent shape rate. The traffic
class named acl_102 requests 30 percent of the bandwidth. The parent policy map named outer_policy
shapes traffic at 768 kbps. The child policy is applied to the parent class-default class. The parent policy
is applied to the map class named PQ_FR_CLASS_0. This map class sets the fragment size at 768 bytes.
The map class is applied to DLCI 27 on serial interface 5/0/0/1:0.1.

Purpose
Assigns a data-link connection identifier (DLCI) to the Frame
Relay interface or subinterface. Enters Frame Relay DLCI
configuration mode.
dlci is a number that identifies the data-link connection on the
interface or subinterface.
(Optional) ietf sets the encapsulation method to comply with the
Internet Engineering Task Force (IETF) standard (RFC 1490).
Use this keyword when connecting to another vendor's equipment
across a Frame Relay network.
(Optional) cisco indicates to use Cisco's own encapsulation,
which is a 4-byte header, with 2 bytes to identify the data-link
connection identifier (DLCI) and 2 bytes to identify the packet
type. This is the default encapsulation type.
Associates a map class with the individual DLCI.
name is the name of the map class that you want to associate with
the DLCI.
Note
shows how use a hierarchical policy when fragmenting packets on a Frame Relay DLCI.
Fragmenting and Interleaving Real-Time and Nonreal-Time Packets
The router applies the service policy configured in the
map class to only this individual DLCI.
