Setting Up Link Quality Monitoring

When you turn on the link quality monitoring and reporting function for an

interface, PPP monitors the quality of the point-to-point link as a percentage of

sent packets received on each end of the link. When the average quality falls

below the threshold you specify, PPP brings down the link. The driver software

automatically brings the link back up and renegotiates the connection.

By default, link quality monitoring is disabled. If you do not want to enable this

feature, accept the default value.

If two routers are configured for different link quality reporting periods, they

negotiate to the lower value, so that the period is the same on both sides of the

link.

Enabling Link Quality Monitoring and Reporting

To turn on link quality monitoring and reporting for the interface, set the Link

Quality Protocol parameter to LINKQR.

When you enable link quality monitoring and reporting through the link quality

protocol, you are turning on monitoring only for the local router. The router on

which you enable it is responsible for monitoring link quality for the connection.

By default, link quality monitoring and reporting is disabled.

If you do not enable link quality monitoring and reporting, ignore the rest of the

link quality parameters.

Establishing the Timing of Link Quality Reports

You can specify which peer is responsible for running the link quality report timer

and set the maximum interval between the transmission of link quality report

packets.

Note:

PPP supports link quality monitoring over standard synchronous

interfaces only. PPP does not support link quality monitoring over

asynchronous or high-speed serial interfaces (HSSI).
