Performing Diagnostics

You can use diagnostics to test and verify the functionality of the hardware components of your system (chassis, supervisor engines, modules, and ASICs) while your Catalyst 4500 series switch is connected to a live network. Diagnostics consists of packet-switching tests that test hardware components and verify the data path and control signals.

Online diagnostics are categorized as bootup, on-demand, schedule, or health-monitoring diagnostics. Bootup diagnostics run during bootup; on-demand diagnostics run from the CLI; scheduled diagnostics run at user-designated intervals or specified times when the switch is connected to a live network; and health-monitoring runs in the background.

This chapter consists of these sections:

•Configuring Online Diagnostics

•Performing Diagnostics

•Power-On Self-Test Diagnostics

Note For complete syntax and usage information for the switch commands used in this chapter, refer to the Catalyst 4500 Series Switch Cisco IOS Command Reference and related publications at this location:

Configuring Online Diagnostics

These sections describe how to configure online diagnostics:

•Configuring On-Demand Online Diagnostics

•Scheduling Online Diagnostics

Configuring On-Demand Online Diagnostics

You can run on-demand online diagnostic tests from the CLI. You can set the execution action to either stop or continue the test when a failure is detected, or to stop the test after a specific number of failures occur with the failure count setting. The iteration setting allows you to configure a test to run multiple times.

To schedule online diagnostics, perform this task:

Command
Purpose 
Switch# 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.


{

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

Switch# diagnostic ondemand iterations 3

Switch#

 
   
 
    
   
 This example shows how to set the execution action when an error is detected: 
 
    
   
 
    
Switch# diagnostic ondemand action-on-fAilure continue 2

 
   
 
    
   
 
    
Switch# 

 
   
 
     
    
    
   
 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 configure online diagnostics, perform this task: 
 
    
   
 
 
   
 
    
 
      
      
      
 
        
        

          Command 
        
 		 
        
        

          Purpose 
        
 		 
      
 
      
 
        
        
 
         
Switch(config)# diagnostic 
schedule module number 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}}

 
        
 
       
 Schedules on-demand diagnostic tests on the specified module for a specific date and time, how many times to run (iterations), and what action to take when errors are found. 
 		 
      
 
      
    
 
   
 
   
 
   
 
 
    
   
 This example shows how to schedule diagnostic testing on a specific date and time for a specific port on module 6: 
 
    
   
 
    
Switch(config)# diagnostic schedule module 6 test 2 port 3 on may 23 2009 23:32 

 
   
 
    
   
 
    
Switch(config)# 

 
   
 
    
   
 
    
 
   
 
    
   
 This example shows how to schedule diagnostic testing to occur daily: 
 
    
   
 
    
Switch(config)# diagnostic schedule module 6 test 2 port 3 daily 12:34 

 
   
 
    
   
 
    
Switch(config)# 

 
   
 
    
   
 
    
 
   
 
    
   
 This example shows how to schedule diagnostic testing to occur weekly: 
 
    
   
 
    
Switch(config)# diagnostic schedule module 6 test 2 port 3 weekly friday 09:23 

 
   
 
    
   
 
    
Switch(config)# 

 
   
 
     
    
    
   
 Performing Diagnostics 
 
    
   
 After you configure online diagnostics, you can start or stop diagnostic tests or display the test results. You can also see which tests are configured and what diagnostic tests have already run. 
 
    
   
 These sections describe how to run online diagnostic tests after they have been configured: 
 
    
   
 •Starting and Stopping Online Diagnostic Tests 
 
    
   
 •Displaying Online Diagnostic Tests and Test Results 
 
    
   
 •Line card Online Diagnostics 
 
    
   
 •Troubleshooting with Online Diagnostics 
 
   
 
     
   
 
   
 
    
   
 Note Before you enable any online diagnostics tests, enable the logging console or monitor to observe all warning messages. 
 
   
 
   
 
     
   
 
   
 
    
   
 Note When running disruptive tests, only run them when you are connected through the console. When disruptive tests complete, a warning message on the console will recommend that you reload the system to return to normal operation. Strictly follow this warning. 
 
   
 
     
    
    
   
 Starting and Stopping Online Diagnostic Tests 
 
    
   
 After you configure diagnostic tests, you can use the start and stop keywords to begin or end a test. 
 
    
   
 To start or stop an online diagnostic command, perform one of these tasks: 
 
    
   
 
 
   
 
    
 
      
      
      
 
        
        

          Command 
        
 		 
        
        

          Purpose 
        
 		 
      
 
      
 
        
        
 
         
Switch# diagnostic start module 
number test {test_id | 
test_id_range | minimal | complete 
| basic | per-port | 
non-disruptive | all} [port {num | 
port#_range | all}]

 
        
 
       
 Starts a diagnostic test on a port or range of ports on the specified module. 
 		 
      
 
      
 
        
        
 
         
Switch# diagnostic stop module 
number

 
        
 
       
 Stops a diagnostic test on the specified module. 
 		 
      
 
      
    
 
   
 
   
 
   
 
 
    
   
 This example shows how to start a diagnostic test on module 6: 
 
    
   
 
    
Switch# diagnostic start module 6 test 2

        before it starts passing traffic.  Each linecard port is placed in

 
   
 
    
   
 
    
        loopback, and a few packets are injected into the switching fabric

 
   
 
    
   
 
    
        from the cpu to the port.  If the packets are successfully

 
   
 
    
   
 
    
        received by the cpu, the port passes the test.  Sometimes one port

 
   
 
    
   
 
    
        or a group of ports sharing common components fail.  The linecard

 
   
 
    
   
 
    
        is then placed in partial faulty mode.  If no ports can loop back

 Line card Online Diagnostics 
 
    
   
 A line card online diagnostic test verifies that all ports on a line card are working correctly. The test can detect whether the path to the front panel port on the line card is broken. The test cannot indicate where along the path that the problem occurred. 
 
   
 
     
   
 
   
 
    
   
 Note This test is run only for line cards that have stub chips. 
 
   
 
    
   
 Line card online diagnostics runs only once, when the line cards boot. This situation can happen when you insert a linecard or power up a chassis. 
 
    
   
 Line card online diagnostics are performed by sending a packet from the CPU to every port on the line card. Because this packet is marked loopback, the CPU expects to see this packet return from the port. The packet first traverses the ASICs on the supervisor engine card, then travels via the chassis backplane and the stub chip on the line cards to the PHYs. The PHY sends it back down the same path. 
 
   
 
     
   
 
   
 
    
   
 Note The packet does not reach or exit the front panel port. 
 
   
 
     
    
    
    
   
 Troubleshooting with Online Diagnostics 
 
    
   
 A faulty line card occurs if any of the following conditions occurs. 
 
    
   
 •All ports fail 
 
    
   
 •All ports on a stub chip fail 
 
    
   
 •Only one port fails 
 
    
   
 For all of these situations, the output of the show module command would display the status of the line card as faulty:

 Step 1 Enter the command show diagnostic result module 3. 
 
    
   
 If a faulty line card was inserted in the chassis, it will fail the diagnostics and the output will be similar to the following: 
 
    
   
 
    
Current bootup diagnostic level: minimal

 Issue an RMA for the line card, contact TAC, and skip steps 2 and 3. 
 
    
   
 The output may display the following: 
 
    
   
 
    
module 3:

    	1) linecard-online-diag --------------------> .

 
   
 
    
   
 
    
 
   
 
    
   
 The message indicates that the line card passed online diagnostics either when it was inserted into the chassis the last time or when the switch was powered up (as reported by the "."). You need to obtain additional information to determine the cause. 
 
    
   
 Step 2 Insert a different supervisor engine card and reinsert the line card. 
 
    
   
 If the linecard passes the test, it suggests that the supervisor engine card is defective. 
 
    
   
 Issue an RMA for the supervisor engine, contact TAC, and skip step 3. 
 
    
   
 Because online diagnostics does not run on the supervisor engine card, you cannot use the 
#show diagnostic module 1 command to test whether the supervisor engine card is faulty. 
 
    
   
 Step 3 Reinsert the linecard in a different chassis. 
 
    
   
 If the linecard passes the test, the problem is associated with the chassis. 
 
    
   
 Issue an RMA for the chassis and contact TAC. 
 
   
 
    
     
    
    
    
   
 Power-On Self-Test Diagnostics

 •Overview 
 
    
   
 •Sample POST Results 
 
    
   
 •Power-On Self-Test Results for Supervisor Engine V-10GE 
 
    
   
 •Troubleshooting the Test Failures 
 
     
    
    
    
   
 Overview 
 
    
   
 All Catalyst 4500 series switches have power-on self-test (POST) diagnostics that run whenever a supervisor engine boots. POST tests the basic hardware functionality for the supervisor switching engine, its associated packet memory and other on-board hardware components. The results of the POST impacts how the switch boots, because the health of the supervisor engine is critical to the operation of the switch. The switch might boot in a marginal or faulty state. 
 
    
   
 POST is currently supported on the following supervisor engines: 
 
    
   
 •WS-X4014 
 
    
   
 •WS-X4515 
 
    
   
 •WS-X4516 
 
    
   
 •WS-X4516-10GE 
 
    
   
 •WS-X4013+ 
 
    
   
 •WS-X4013+TS 
 
    
   
 •WS-X4013+10GE 
 
    
   
 •WS-C4948G 
 
    
   
 •WS-C4948G-10GE 
 
    
   
 •ME-4924-10GE 
 
    
   
 •WS-X45-SUP6-E 
 
    
   
 •WS-X45-SUP6L-E 
 
    
   
 The POST results are indicated with a period (.) or a Pass for Pass, an F for a Fail and a U for Untested. 
 
   
 
     
   
 
   
 
    
   
 Note A supervisor engine runs POST during boot up (insertion or power on). In a redundant topology, both supervisor engines run POST individually. Switchovers are allowed only after both supervisor engines have booted. During a switchover, the standby supervisor engine does not run POST again because it has already booted. 
 
   
 
     
    
    
   
 Sample POST Results 
 
    
   
 For all the supervisor engines, POST performs CPU, traffic, system, system memory, and feature tests. 
 
    
   
 For CPU tests, POST verifies appropriate activity of the supervisor SEEPROM, temperature sensor, and Ethernet end-of-band channel (EOBC), when used. 
 
    
   
 The following example illustrates the output of a CPU subsystem test on all supervisor engines except the WS-X4013+TS:

 For traffic tests, POST sends packets from the CPU to the switch. These packets loop several times within the switch core and validate the switching, the Layer 2 and the Layer 3 functionality. To isolate the hardware failures accurately, the loop back is done both inside and outside the switch ports. 
 
    
   
 The following example illustrates the output of a Layer 2 traffic test at the switch ports on the supervisor engines WS-X4516, WS-X4516-10GE, WS-X4013+10GE, WS-C4948G-10GE:

 POST also performs tests on the packet and system memory of the switch. These are numbered dynamically in ascending order starting with 1 and represent different memories.

 POST also tests the NetFlow services card (Supervisor Engine IV and Supervisor Engine V) and the NetFlow services feature (Supervisor Engine V -10GE). Failures from these tests are treated as marginal, as they do not impact functionality of the switch (except for the unavailability of the NetFlow features):

 Note Supervisor Engine VI-E retains most of the previous supervisor engines' POST features including the CPU subsystem tests, Layer 3 and Layer 2 traffic tests, and memory tests. Redundant ports on redundant systems are not tested. All POST diagnostics are local to the supervisor engine running the tests.

 Power-On Self-Test Results for Supervisor Engine V-10GE 
 
    
   
 For the Supervisor Engine V-10GE (WS-X4516-10GE), POST tests extra redundancy features on the 10-Gigabit ports. 
 
    
   
 The following topics are discussed: 
 
    
   
 •POST on the Active Supervisor Engine 
 
    
   
 •Sample POST Results on an Active Supervisor Engine 
 
    
   
 •POST on a Standby Supervisor Engine 
 
    
   
 •Sample Display of the POST on a Standby Supervisor Engine 
 
     
    
    
   
 POST on the Active Supervisor Engine 
 
    
   
 The active supervisor engine tests the remote redundant 10-Gigabit ports on the standby supervisor engine if it is present when the active supervisor engine is booting. The status of the port is displayed as 
"Remote TenGigabit Port Status." If no standby supervisor engine is present, the remote port status is always displayed as Untested. This situation persists even after a new standby supervisor engine is inserted. The remaining tests are conducted using only the Gigabit ports' configuration. 
 
    
   
 After the active supervisor engine has completed the bootup diagnostics, if the standby supervisor engine is now removed, the remote port status is changed to Untested in the overall diagnostic results.

 POST on a Standby Supervisor Engine 
 
    
   
 Ports 62 and 63 of the supervisor engine always remain Untested (U). Because the standby supervisor engine never tests the remote 10-Gigabit port on the active supervisor engine, the remote 10-Gigabit port status on the standby supervisor engine is always Untested. The supervisor engine performs the remaining tests using the Gigabit ports' configuration. 
 
   
 
     
   
 
   
 
    
   
 Note On a redundant chassis, concurrent POST is supported on supervisor engines that are already inserted. However, if a second supervisor engine is inserted while the first one is loading, you might boot the first supervisor engine in a faulty IOS state (POST will abort and some of the POST's tests will be bypassed). This situation only happens during concurrent bootup of the supervisor engines. You should not insert any additional supervisor engines in the empty supervisor engine slot while an already seated supervisor engine is running POST. The POST sequence is completed when the "Exiting to ios..." message is displayed.

 Note To ensure that the maximum number of ports are tested, ensure that both supervisor engines are present on power-up. 
 
   
 
     
    
    
    
   
 Troubleshooting the Test Failures 
 
    
   
 A failure of any of the POST tests reflects a problem with the hardware on the supervisor engine. 
Cisco IOS boots the supervisor engine with limited functionality, allowing the user to evaluate and display the diagnostic test results. To determine the failure cause, do one of the following: 
 
    
   
 •Evaluate whether the hardware failure is persistent by power cycling the supervisor engine to rerun the POST tests. 
 
    
   
 •Remove and reinsert the supervisor engine into the chassis to ensure that the seating is correct. 
 
    
   
 Please call the Cisco Systems customer support team for more information. 
 
   
 
     
   
 
   
 
    
   
 Note On a redundant chassis, concurrent POST is supported on supervisor engines that are already inserted. However, if a second supervisor engine is inserted while the first one is loading, you might boot the first supervisor engine in a faulty Cisco IOS state (POST will abort, and some of the POST"s tests will be bypassed). This situation only happens during concurrent bootup of the supervisor engines. You should not insert any additional supervisor engines in the empty supervisor engine slot while an already seated supervisor engine is running POST. The POST sequence is completed when the "Exiting to ios..." message is displayed.
