Configuration Example for Attaching a Map Class to a Frame Relay DLCI
Example 16-11
example, fragmentation is enabled in the map class named lfi_map_class and the fragment size is set at
300 bytes. The QoS service policy named policy_13 is also applied to the map class for outbound traffic.
The main interface 5/0/0/1:0 has two subinterfaces with DLCI configured. The lfi_map_class is attached
to DLCI 17 on subinterface 5/0/0/1:0.1. Therefore, the router fragments and interleaves only the traffic
on DLCI 17 and applies the QoS actions defined in policy_13 to only DLCI 17 traffic.
Example 16-11 Attaching a Map Class to a Frame Relay DLCI
Router(config)# map-class frame-relay lfi_map_class
Router(config-map-c)# frame-relay fragment 300
Router(config-map-c)# service-policy output policy_13

Purpose
Specifies the IP address and subnet mask assigned to the
subinterface.
address is the IP address.
mask is the subnet mask for the associated IP address.
Disables the translation of a directed broadcast to physical
broadcasts. Instead, the directed broadcasts are dropped.
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 DLCI.
name is the name of the map class.
Note
shows how to attach a map class with LFI enabled to a Frame Relay DLCI. In the
Cisco 10000 Series Router Quality of Service Configuration Guide
When a map class is associated with a DLCI, only traffic
on the DLCI is fragmented.
