516 CHAPTER 31: PPP AND MP CONFIGURATION COMMANDS
quality every ten LQRs, and brings the link up if the results of three consecutive
calculations are higher than the resume-percentage. This means a disabled link
must experience 30 keepalive periods before it can go up again. If a large
keepalive period is specified, it may take long time for the link to go up.
When enabling LQC at both ends of a PPP link, you must set the same parameters
on the devices involved. Normally, it is not recommended to enable LQC at both
ends of a link. In addition, LQC on dial-up line is not recommended too. This is
because that when a link on dial-up line is disabled, the DCC would disconnect
the dial-up line, causing LQC not to work. It is not until there are data to transmit,
will DDC brings the dial-up line up again and LQC resumes to work.
Example # Enable LQC on interface Serial 1/0, setting close-percentage to 90 and
resume-percentage to 95.

Description Use the
ppp mp command to enable MP on the interface encapsulated with PPP.
Use the undo ppp mp command to disable this feature.
By default, the interface encapsulated with PPP operates in the Single PPP mode.
To increase bandwidth, multiple PPP links can be bound to form a logical MP
interface.
Example # Configure the PPP encapsulated interface Serial 1/0 to work in MP mode.
<Sysname> system-view
[Sysname] interface serial 1/0
[Sysname-Serial1/0] ppp mp
