Frame-Relay Fragment

I have a 3640 and several 2611's running 12.2(5d). I am trying to issue the frame-relay fragment command under map-class frame-relay but it is not a option. I want to break up any large packets that would cause latency in the voice traffic. Is there another way to do this other than the frame-relay fragment command?

Re: Frame-Relay Fragment

There are 3 ways in which you could configure frame relay fragmentation. They are:

1.Using the "frame-relay fragment" command, as per the FRF.12 fragmentation.

2.Using the FRF.11 fragmentation. This method is not recommended for use with Voice over IP (VoIP).

3.Cisco Proprietary fragmentation using the command "vofr cisco"

The 3rd options could be the solution for your query.

For more details on this, please refer to the following document:
