R3303-HP HSR6800 Routers Layer 2 - WAN Command Reference

66
Parameters
max-bind-num: Maximum number of links allowed in an MP bundle, in the range of 1 to 128.
Usage guidelines
Use the default setting in normal cases. Inappropriate use of this command can cause PPP performance
degradation. Make sure you understand the impact of this command on your network before you use it.
If the maximum number of links allowed in an MP bundle configured is less than the actual link number
of an MP bundle, you will fail in MP binding. Therefore, make sure that the maximum link number
configured is larger than the actual one.
After you change the maximum number of bound links for an MP bundle, you must shut down and then
bring up all the physical interfaces bound to the MP bundle for the modification to take effect.
Examples
# Set the maximum number of links allowed in an MP bundle to 12.
<Sysname> system-view
[Sysname] interface virtual-template 0
[Sysname-Virtual-Template0] ppp mp max-bind 12
Related commands
ppp mp
ppp mp min-fragment
Use ppp mp min-fragment to set the minimum MP packet size for fragmentation.
Use undo ppp mp min-fragment to restore the default, or 128 bytes.
Syntax
ppp mp min-fragment size
undo ppp mp min-fragment
Views
Virtual template interface view, MP-group interface view
Default command level
2: System level
Parameters
size: Minimum MP packet size for fragmentation to be set, in the range of 128 to 1500 (in bytes). MP
outgoing packets smaller than this value will not be fragmented, but those larger than or equal to this
value will be fragmented.
Usage guidelines
If MP bundle is implemented through hardware (CPOS chip for example), the minimum MP packet size
for fragmentation varies with chips (the fragment size on certain chips can only be 128, 256, and 512
bytes). In this case, make sure the setting configured with the ppp mp min-fragment command conforms
to the hardware specifications for the MP bundle to be created and the sub-channel LCP link to be
established successfully.
After executing the ppp mp min-fragment command, you must re-enable all the bound ports (by using
the shutdown and undo shutdown commands) for the new setting to take effect.
