Usage guidelines
With fragmentation enabled, an MFR interface fragments packets larger than the set fragment size
and sends the fragments over bundle links in a round robin manner. This reduces the transmission
delay of real-time packets.
Examples
# Set the maximum fragment size allowed on interface MFR 0/0/2 to 70 bytes.
<Sysname> system-view
[Sysname] interface mfr 0/0/2
[Sysname-MFR0/0/2] mfr fragment-size 70
Related commands

mfr timer lost-fragment
Use
mfr timer lost-fragment
to set the amount of time that an MFR interface waits for an expected
fragment.
Use
undo mfr timer lost-fragment
to restore the default.
Syntax
mfr timer lost-fragment seconds
undo mfr timer lost-fragment
Default
An MFR interface waits for an expected fragment for 30 seconds before it declares the fragment lost.

Parameters
seconds
: Specifies a value for the wait timer, in the range of 1 to 255 seconds.
Usage guidelines
The receiving end buffers the fragments of a packet before receiving all fragments of the packet. If
any fragments are missing, the received fragments stay in the buffer. This processing wastes buffer
resources.
The wait timer starts when the receiving end receives the first fragment of a packet. When the wait
timer expires, the receiving end checks whether all fragments are received. If not all fragments are
received, the receiving end discards all received fragments of the packet to release buffer resources.
Examples
# Set the wait time to 20 seconds for interface MFR 0/0/2.
<Sysname> system-view
[Sysname] interface mfr 0/0/2
[Sysname-MFR0/0/2] mfr timer lost-fragment 20
