Ppp Mp Timer Lost-Fragment - H3C MSR810 Command Reference Manual

Parameters
size: Specifies the MP sort buffer size factor in the range of 1 to 64.
Usage guidelines
The MP sort buffer size = the number of channels in the current MP bundle × size. You can use
the display ppp mp command to view the number of member channels in an MP bundle. If the
calculated MP sort buffer size is 20, the MP sort buffer can sort 20 packets.
When MP is used, the received packets might be out of order. The sort buffer is used to re-sort
packets. A large sort buffer results in better re-sorting but increases delay. For voice packets, the
transmission delay should be minimized.
Examples
# Set the MP sort buffer size factor to 64 on MP-group 2/0/0.

seconds: Specifies the timer for MP to wait for the expected fragment, in the range of 1 t o 255
seconds.
Usage guidelines
A receiving end puts the received fragments in the buffer and reassembles them when it receives all
the packet's fragments. You can configure a timer for MP to wait for the expected fragments. When
the receiving end receives the first fragment of a packet, it starts the timer. When the timer expires,
the system checks whether or not all fragments have arrived. If they have all arrived, the system
