ppp quality percentage
no ppp quality
Specifies the link quality threshold. Range is 1 to 100.
To enable Link Quality Monitoring (LQM) on a serial interface, use the ppp quality command in interface configuration mode. To disable LQM, use the no form of this command.
The percentages are calculated for both incoming and outgoing directions. The outgoing quality is calculated by comparing the total number of packets and bytes sent to the total number of packets and bytes received by the destination node. The incoming quality is calculated by comparing the total number of packets and bytes received to the total number of packets and bytes sent by the destination node.
If the link quality percentage is not maintained, the link is deemed to be of poor quality and is taken down. LQM implements a time lag so that the link does not bounce up and down.
The following example enables LQM on serial interface 2:
interface serial 2
ppp quality 80
