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:

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

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

Issue the no version of the command to return to the default setting for the slot:
host1(config)# no slot ignore-diagnostic-failure 12

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:

From the boot prompt, issue the option ignore-srp-diagnostic-results command.
:boot##option ignore-srp-diagnostic-results

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

Note: In the burn-in mode, the done bit of the configuration (CFG) register is used to detect the blank PROM. When the FPGA for SFM module is being loaded, the system examines whether the done bit is set for blank PROMs. In the burn-in mode, if the done bit is not set, the testing utility halts and the FPGA is not programmed. At this point, the system displays a message stating that the done bit is not set for the blank PROM. If the done bit has been previously set for blank PROMs, the test that is performed successfully completes and the programming of the FPGA continues.
