Configuring Online Diagnostics

The online diagnostics detect problems in the following areas:
Online diagnostics is one of the requirements for the high availability feature. High availability is a set
of quality standards that seek to limit the impact of equipment failures on the network. A key part of high
availability is detecting hardware failures and taking corrective action while the router runs in a live
network. Online diagnostics in high availability detect hardware failures and provide feedback to high
availability software components to make switchover decisions.
Online diagnostics are categorized as bootup, on-demand, scheduled, or health monitoring diagnostics.
Bootup diagnostics run during bootup; on-demand diagnostics run from the CLI; schedule diagnostics
run at user-designated intervals or specified times when the router is connected to a live network; and
health-monitoring runs in the background.
