45Use 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 oflinks 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 thephysical 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. system-view[Sysname] interface Mp-group 4/1/28[Sysname-Mp-group4/1/28] ppp mp max-bind 10ppp mp min-fragmentSyntaxppp mp min-fragment sizeundo ppp mp min-fragmentViewMP-group interface viewDefault level2: System levelParameterssize: Minimum MP packet size for fragmentation to be set, which ranges from 128 to 1500 (in bytes). MPoutgoing packets smaller than this value will not be fragmented, while those larger than or equal to thisvalue will be fragmented.DescriptionUse 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 sizefor fragmentation varies with chips (the fragment size on certain chips can only be 128, 256, and 512bytes). In this case, make sure the setting specified by the ppp mp min-fragment command conforms tothe hardware specification for the MP bundle and the sub-channel LCP link to be establishedsuccessfully.• After configuring the ppp mp min-fragment command, you must re-enable all the bundled physicalinterfaces for the new setting to take effect.
