• Fragments the large packets into small fragments.
• Adds the fragments to the queues along with the voice packets.

To configure LFI:
Ste
Command
Remarks
1. Enter system view.
system-view N/A
2. Enter VT interface, MP-group
interface, or dialer interface view.
interface { dialer | mp-group
| virtual-template }
mp-number
N/A
3. Enable LFI.
ppp mp lfi enable
By default, LFI is disabled.
Disabling LFI also removes the
user-configured settings of the
maximum LFI fragment delay and
size.
4. Set the maximum LFI fragment
transmission delay and the
maximum LFI fragment size (in
bytes).
• ppp mp lfi
delay-per-frag time
• ppp mp lfi size-per-frag
size
By default, the maximum LFI
fragment transmission delay is 10
ms, and the maximum LFI fragment
size is the expected bandwidth of
the interface times the maximum
delay divided by 8.
