Chapter 55 Configuring Generic Online Diagnostics
Configuring Online Diagnostics
The online diagnostics detect problems in the following areas:
• Hardware components
• Interfaces (GBICs, Ethernet ports, and so forth)
• Connectors (loose connectors, bent pins, and so forth)
• Solder joints
• Memory (failure over time)
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.
Configuring Online Diagnostics
These sections describe how to configure online diagnostics:
• Setting Bootup Online Diagnostics Level, page 55-2
• Configuring On-Demand Online Diagnostics, page 55-3
• Scheduling Online Diagnostics, page 55-4
• Configuring Health-Monitoring Diagnostics, page 55-5
Setting Bootup Online Diagnostics Level
You can set the bootup diagnostics level as minimal or complete or you can bypass the bootup
diagnostics entirely. Enter the complete keyword to run all bootup diagnostic tests; enter the minimal
keyword to run only EARL tests and loopback tests for all ports in the router. Enter the no form of the
command to bypass all diagnostic tests. The default bootup diagnositcs level is minimal.
To set the bootup diagnostic level, perform this task:
This example shows how to set the bootup online diagnostic level:
Router(config)# diagnostic bootup level complete
Router(config)#
This example shows how to display the bootup online diagnostic level:
Router(config)# do show diagnostic bootup level
Router(config)#
Command Purpose
Router(config)# diagnostic bootup level {minimal |
complete}
Sets the bootup diagnostic level.
