Usage guidelines
If MP binding is implemented through hardware (for example, CPOS chip), the minimum MP packet
fragmentation size varies with chips. The minimum MP packet fragmentation size on certain chips can
only be 128, 256, or 512 bytes. To successfully create an MP bundle and establish a sub-channel LCP link,
make sure the setting configured with the ppp mp min-fragment command conforms to the hardware
specifications.
Examples
# Set the minimum MP packet fragmentation size to 500 bytes.
<Sysname> system-view
[Sysname] interface mp-group 1
[Sysname-MP-group1] ppp mp min-fragment 500
