Usage guidelines
PPP LQC monitors the quality of PPP links (including those in MP bundles) in real time.
If PPP LQC is not enabled, each end of a PPP link sends keepalive packets to its peer periodically. After
you enable PPP LQC, LQR packets replace keepalive packets to monitor the link.
With PPP LQC enabled, the system determines the link quality by processing LQR packets received and
disables the link if two successive link quality samples are below the PPP LQC close-percentage. After a
PPP link is disabled by PPP LQC, the system samples the link quality once in each period ten times of LQR
packet sending intervals, and enables the link up if three successive link quality samples are higher than
the PPP LQC resume-percentage. A disabled link must experience at least 30 keepalive periods before it
can be enabled again. Therefore, make sure the keepalive period is proper in order that PPP links can be
enabled timely.
