Enabling FRF.12 Fragmentation on a Map Class
To enable FRF.12 Fragmentation on a Frame Relay map class, enter the following commands beginning
in global configuration mode:
Command
Step 1
Router(config)# map-class frame-relay
map-class-name
Step 2
Router(config-map-c)# frame-relay fragment
fragment_size
Step 3
Router(config-map-c)# service-policy
{input | output} policy-map-name
Step 4
Router(config-map-c)# no frame-relay

Fragmenting and Interleaving Real-Time and Nonreal-Time Packets
Purpose
Creates or modifies a map class and enters map-class
configuration mode.
map-class-name identifies the map class.
Enables the fragmentation of Frame Relay frames on a Frame
Relay map class.
fragment_size specifies the number of payload bytes from the
original Frame Relay frame that go into each fragment. This
number excludes the Frame Relay header of the original frame.
Valid values are from 16 to 1600 bytes. The default is 53 bytes.
All of the fragments of a Frame Relay frame, except the
Note
last, have a payload size that is equal to the fragment_size.
The last fragment has a payload that is less than or equal
to the fragment_size.
Applies the service policy you specify to the map class.
input indicates to apply the service policy to the traffic on the
inbound interface.
output indicates to apply the service policy to the traffic on the
outbound interface.
Note
For QoS policies containing the bandwidth, priority,
random-detect, queue-limit, and shape commands, you
must specify the output keyword. The router ignores
these commands when you use them with the input
keyword.
policy-map-name is the name of the policy map.
Disables Frame Relay adaptive traffic shaping.
