Usage guidelines
Disabling LFI also removes the user-configured settings of the maximum LFI fragment transmission delay
and size.

# Enable LFI on interface MP-group 1.
<Sysname> system-view
[Sysname] interface mp-group 1
[Sysname-MP-group1] ppp mp lfi enable
Related commands

ppp mp lfi size-per-frag
Use ppp mp lfi size-per-frag to set the maximum LFI fragment size (in bytes).
Use undo ppp mp lfi size-per-frag to restore the default.
Syntax
ppp mp lfi size-per-frag size
undo ppp mp lfi size-per-frag
Default
The maximum LFI fragment size is derived from this formula: (Expected bandwidth of the interface x
Maximum LFI fragment transmission delay)/8.
Views
VT interface view, dialer interface view, MP-group interface view
Predefined user roles

Parameters
size: Specifies the maximum LFI fragment size in the range of 40 to 1500 bytes.
Usage guidelines
When LFI is enabled and both this command and the ppp mp lfi delay-per-frag command are
configured, the maximum LFI fragment size is the value configured with the ppp mp lfi size-per-frag
command.
Examples
# Configure the maximum LFI fragment size as 80 bytes on interface MP-group 1.
<Sysname> system-view
[Sysname] interface mp-group 1
[Sysname-MP-group1] ppp mp lfi size-per-frag 80
