Online Diagnostics
The Catalyst 6500 series systems running Cisco IOS have many levels of online diagnostic capabilities.
The online diagnostics are divided into four categories:
Bootup—Bootup diagnostics automatically run during bootup, module OIR, or switchover to a backup
supervisor engine.
Background Health—Monitoring diagnostic tests are continuously run by the system to monitor system
health.
On-demand online diagnostics—On-demand online diagnostics can be used to run any test from the CLI.
You can also run on-demand online diagnostics to perform a sanity check on the system hardware. Some
of these tests are disruptive and will impact traffic flow.You must follow the on-demand diagnostic
guidelines exactly to avoid false failures.
Scheduled Diagnostics—Scheduled diagnostics can be used to run any of the above tests at user
designated intervals.
For complete information on the online diagnostic tests and how to run them, refer to Chapter 51 in the
Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide, Release 12.2SX.
