Configuring Online Diagnostics Chapter 55 Configuring Generic Online Diagnostics Step 5 Run the exhaustive-memory tests. Before running the exhaustive memory tests, all health-monitoring tests should be disabled because the tests will fail with health monitoring enabled and the switch will take recovery action. Disable the health-monitoring diagnostic tests by using the no diagnostic monitor module 1 test all command. Perform the exhaustive memory tests in the following order: 1. TestFibTcamSSRAM 2. TestAclQosTcam 3. TestNetFlowTcam 4. TestAsicMemory 5. TestAsicMemory You must reboot the after running the exhaustive memory tests before it is operational again. You cannot run any other tests on the router after running the exhaustive memory tests. Do not save the configuration when rebooting as it will have changed during the tests. After the reboot, reenable the health monitoring tests using the diagnostic monitor module 1 test all command To set the bootup diagnostic level, perform this task: Command Router# diagnostic ondemand {iteration iteration_count} | {action-on-error {continue | stop}[error_count]} Purpose Configures on-demand diagnostic tests to run, how many times to run (iterations), and what action to take when errors are found. This example shows how to set the on-demand testing iteration count: Router# diagnostic ondemand iteration 3 Router# This example shows how to set the execution action when an error is detected: Router# diagnostic ondemand action-on-error continue 2 Router# Scheduling Online Diagnostics You can schedule online diagnostics to run at a designated time of day or on a daily, weekly, or monthly basis. You can schedule tests to run only once or to repeat at an interval. Use the no form of this command to remove the scheduling. To schedule online diagnostics, perform this task: Command Router(config)# diagnostic schedule module 1 test {test_id | test_id_range | all} [port {num | num_range | all}] {on mm dd yyyy hh:mm} | {daily hh:mm} | {weekly day_of_week hh:mm} Purpose Schedules on-demand diagnostic tests for a specific date and time, how many times to run (iterations), and what action to take when errors are found. 55-4 Cisco 7600 Series Router Cisco IOS Software Configuration Guide, Release 12.2SX OL-4266-08

Configuring Generic Online Diagnostics

Configuring Online Diagnostics

Step 5

Run the exhaustive-memory tests.

Before running the exhaustive memory tests, all health-monitoring tests should be disabled because the

tests will fail with health monitoring enabled and the switch will take recovery action. Disable the

health-monitoring diagnostic tests by using the

no diagnostic monitor module 1 test all

command.

Perform the exhaustive memory tests in the following order:

TestFibTcamSSRAM

TestAclQosTcam

TestNetFlowTcam

TestAsicMemory

You must reboot the after running the exhaustive memory tests before it is operational again. You cannot

run any other tests on the router after running the exhaustive memory tests. Do not save the configuration

when rebooting as it will have changed during the tests. After the reboot, reenable the health monitoring

tests using the

diagnostic monitor module 1 test all

command

To set the bootup diagnostic level, perform this task:

This example shows how to set the on-demand testing iteration count:

Router#

diagnostic ondemand iteration 3

Router#

This example shows how to set the execution action when an error is detected:

Router#

diagnostic ondemand action-on-error continue 2

Router#

Scheduling Online Diagnostics

You can schedule online diagnostics to run at a designated time of day or on a daily, weekly, or monthly

basis. You can schedule tests to run only once or to repeat at an interval. Use the

form of this

command to remove the scheduling.

To schedule online diagnostics, perform this task:

Command

Purpose

Router#

diagnostic ondemand

{

iteration

iteration_count

} | {

action-on-error

{

continue

stop

}[

error_count

]}

Configures on-demand diagnostic tests to run, how many

times to run (iterations), and what action to take when errors

are found.

Command

Purpose

Router(config)#

diagnostic schedule module 1

test

{

test_id

test_id_range

all

}

[

port

{

num

num_range

all

}] {

yyyy

} | {

daily

} | {

weekly

day_of_week

}

Schedules on-demand diagnostic tests for a specific date and

time, how many times to run (iterations), and what action to

take when errors are found.
