Use the default setting in normal cases. Use this command under the guidance of a technical engineer,
because changing the maximum number of links in an MP bundle can affect its PPP performance.
NOTE:
To make sure that links can be bundled to an MP bundle successfully, configure the actual number of
•
links assigned to an MP bundle smaller than the maximum number of links allowed in the bundle.
After you change the maximum number of links allowed in an MP bundle, you must re-enable all the
•
physical interfaces in the MP bundle for the modification to take effect.
Related commands: ppp mp.
Examples
# Set the maximum number of links allowed in MP-group 4/1/28 to 10.
<Sysname> system-view
[Sysname] interface Mp-group 4/1/28
[Sysname-Mp-group4/1/28] ppp mp max-bind 10
ppp mp min-fragment
Syntax
ppp mp min-fragment size
undo ppp mp min-fragment
View
MP-group interface view
Default level
2: System level
Parameters
size: Minimum MP packet size for fragmentation to be set, which ranges from 128 to 1500 (in bytes). MP
outgoing packets smaller than this value will not be fragmented, while those larger than or equal to this
value will be fragmented.
Description
Use the ppp mp min-fragment command to set the minimum MP packet size for fragmentation.
Use the undo ppp mp min-fragment command to restore the default.
By default, the minimum MP packet size for fragmentation is 512 bytes.
NOTE:
•
If MP bundle is implemented through hardware (CPOS chips 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 specified by the ppp mp min-fragment command conforms to
the hardware specification for the MP bundle and the sub-channel LCP link to be established
successfully.
After configuring the ppp mp min-fragment command, you must re-enable all the bundled physical
•
interfaces for the new setting to take effect.
