devices are unique. You must reconfigure an endpoint descriptor for a device if the default endpoint
descriptor (device name) cannot uniquely identify the MP bundle at the remote end.
When MP is configured by using an MP-group interface, the negotiating endpoints do not base their
binding decisions on the endpoint descriptor. By default, the endpoint descriptor of an interface in an
MP-group is the MP-group interface name. If you configure an endpoint descriptor for the interface, the
configured MP endpoint descriptor takes effect.
If the endpoint descriptor exceeds 20 bytes, the first 20 bytes are taken as the endpoint descriptor.
Examples
# Configure the endpoint descriptor of Serial 2/1/0 as 123 456 .
<Sysname> system-view
[Sysname] interface serial 2/1/0
[Sysname-Serial2/1/0] ppp mp endpoint 123456
ppp mp fragment disable
Use ppp mp fragment disable to disable MP fragmentation.
Use undo ppp mp fragment disable restore the default.
Syntax

Usage guidelines
If the peer device does not support fragment reassembly, you must configure the ppp mp fragment
disable command to disable MP fragmentation on the local device. This enables the two devices to
communicate. After that, outgoing packets are not fragmented, but they still carry an MP sequence
number and fragment tag.
After you configure the ppp mp fragment disable command on an interface, the settings configured with
the ppp mp lfi enable and ppp mp min-fragment commands do not take effect on the interface.
Examples
# Disable MP fragmentation on interface MP-group 1.
<Sysname> system-view
[Sysname] interface mp-group 1
[Sysname-MP-group1] ppp mp fragment disable
