# Ignoring Diagnostic Test Failures

You can ignore diagnostic test failures on the line module or SRP. This enables you to categorize diagnostic failures and determine the impact on functional behavior.

To ignore diagnostic test failure on the line module or SRP:

1. Select the slot number of the slot that you want to ignore diagnostic test failure. This information is stored on the SRP and is independent of the hardware in the slot. You can reload a particular slot to boot the module to the operational image.
   host1#slot ignore-diagnostic-failure 0
2. Issue the show environment command to check which line modules are configured to ignore diagnostics test failure.

       host1#show environment
       chassis: 14 slot (id 0x5, rev. 0x1)
           fabric: 40 Gbps (rev. 0)
           fans: fanSubsystemOk
           nvs: ok (488MB flash disk, 43% full), matches running config
           power: A ok, B not present
           srp redundancy: mode is high-availability, state initializing
               auto-sync enabled, switch-on-error enabled
               sync in progress
           slots: ok
               online: 0 6 12
               standby: 7
               empty: 1 2 3 4 5 8 9 10 11 13
               diagnostic failure is ignored on slot: 0
           line redundancy: none
           temperature: ok
           timing: primary
               primary: internal SC oscillator (ok)
               secondary: internal SC oscillator (ok)
               tertiary: internal SC oscillator (ok)
               auto-upgrade enabled
           system operational: yes

3. Issue the no version of the command to return to the default setting for the slot:
   host1(config)# no slot ignore-diagnostic-failure 12
4. Issue the show environment command to check that the slot no longer ignores diagnostic test failures :

       host1#show environment    chassis: 14 slot (id 0x5, rev. 0x1)
           fabric: 40 Gbps (rev. 0)
           fans: fanSubsystemOk
           nvs: ok (488MB flash disk, 43% full), matches running config
           power: A ok, B not present
           srp redundancy: mode is high-availability, state initializing
               auto-sync enabled, switch-on-error enabled
               sync in progress
           slots: ok
               online: 0 6 12
               standby: 7
               empty: 1 2 3 4 5 8 9 10 11 13
               diagnostic failure is ignored on slot: 0,6,7
           line redundancy: none
           temperature: ok
           timing: primary
               primary: internal SC oscillator (ok)
               secondary: internal SC oscillator (ok)
               tertiary: internal SC oscillator (ok)
               auto-upgrade enabled
           system operational: yes

If an SRP failure occurs when the router boots from the factory defaults or when your configuration is lost, you can ignore test failures from the boot menu:

1. From the boot prompt, issue the option ignore-srp-diagnostic-results command.
   :boot##option ignore-srp-diagnostic-results
2. Verify that the setting is correct:

       :boot##show options
           no option auto-boot-disable
              option countdown
           no option debug-startup
           no option halt-on-failure
           no option bypass-diagnostics
           no option stay-in-diagnostics
              option ignore-srp-diagnostic-results
           no option instruction-cache-disable
           no option watchdog-disable
           no option redirect-serial
           no option diagnostics-burn-in
           no option start-wdb
           no option start-standby-wdb
           no option assertions-in
           no option memory-debug
           no option disable-backpress
           no option stl-debug
