FRF.12 Fragmentation
Enabling FRF.12 Fragmentation on a Frame Relay Map Class
To enable FRF.12 Fragmentation on a Frame Relay map class, enter the following commands beginning
in global configuration mode:
Step 3
Router(config-pmap-c)#
shape
kbps-value
Shapes traffic to a specified bit rate.
kbps-value
is the bit rate (in kilobits per second) used to shape the
traffic.
Step 4
Router(config-pmap-c)#
service-policy
policy-map-name
Applies the child policy to the parent class-default class.
policy-map-name
is the name of the previously configured child
policy map.
Note
Do not specify the
input
or
output
keyword when
applying a service policy to another child policy or to a
parent policy.

Step 1
Router(config)#
map-class frame-relay
map-class-name
Creates or modifies a map class. Enters map-class configuration
mode.
map-class-name
is the name of the map class.
Step 2
Router(config-map-c)#
service-policy
{
input
|
output
}
policy-map-name
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. For FRF.12 Fragmentation, specify the
output
keyword.
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.
Step 3
Router(config-map-c)#
frame-relay
fragment
fragment_size
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.
