The fragmentation interleaving feature allows for the transmission of higher priority traffic to 
be expedited by setting a maximum frame size. If lower priority traffic exceeds the set frame 
size value, it is fragmented into smaller pieces less than or equal to the set maximum frame 
size. 

When the fragmentation feature is enabled, frame traffic is examined for priority. High priority 
traffic is not fragmented. Fragemented frames are reassembles on the far side (destination) of 
the link. 

The following diagram illustrates this concept:

Fragmentation must be enabled on both ends of the data link for successful fragmentation 
and reassembly to occur.

The maximum frame size should not be set so low that average frame traffic is broken into 
more than 64 fragments.

For information on enabling Frame Relay fragmentation, see Modifying a Virtual Circuit on 
page 29-29.
