Before Calling Alcatel’s Technical Assistance Center

Before calling Alcatel’s Technical Assistance Center (TAC), make sure that you have read through the appropriate section (or sections) and have completed the actions suggested for your system’s problem.

Additionally, do the following and document the results so that the Alcatel TAC can better assist you:

• Have a network diagram ready. Make sure that relevant information is listed, such as all IP addresses

and their associated network masks.

• Have any information that you gathered while troubleshooting the issue to this point available to

provide to the TAC engineer.

• If the problem appears to be with only a few-fewer than four-switches, capture the output from the

show tech-support CLI command on these switches. (See Appendix C, “Technical Support

Commands,” for more information on show tech-support CLI commands.)

When calling Alcatel TAC in order to troubleshoot or report a problem following information can be helpful to get a quick resolution:

• All the dump files that were created, if any

• Output of switch log or the switch log files swlog1.log and swlog2.log

• Configuration file boot.cfg

• A capture of the show microcode command

• A capture of the show module long command

• A capture of the show tech-support command from CLI.

• If a CMM fail over to the redundant CMM happened because of this failure then include this informa-

tion from both of the CMMs.

Dial-in or Telnet access can also helpful for effective problem resolution.

1 Troubleshooting the Switch

System

In order to troubleshoot the system, a basic understanding of the operation of Chassis Management Modules (CMMs) and their interaction with Network Interface (NI) modules is required. Some concepts are covered in this chapter:

• Understanding of the “Diagnosing Switch Problems” chapter in the appropriate OmniSwitch Switch

Management Guide.

• Understanding of the “Using Switch Logging” from the appropriate OmniSwitch Network Configura-

tion Guide is highly recommended.

Introduction Troubleshooting the Switch System

Introduction

The CMM is the Management Module of the switch. All of the critical operations of the switch including the monitoring is the responsibility of the CMM. CMM not only provides monitoring but also synchronizes all of the NI for different operations. The operation of the CMM is the same in OS-6/7/8XXX switches. The only difference is that OS-6/7XXX has the switching fabric inherent to the module whereas OS-8800 has fabric at the back of the chassis.

NI has a build in CPU. Each NI has its own CPU, which acts independently of the CMM. The CPU of the NI has to interact with the CPU on the CMM for certain operations. If this operation becomes out of sync then it can create problems specific to that NI.

In order to troubleshoot the system, an understanding of the CMM and NI operation is essential.

Troubleshooting the Switch System Troubleshooting System for OS-6624/6648 and OS-7/8XXX

Troubleshooting System for OS-6624/6648 and OS-7/8XXX

If the switch is having any problems the first place to look for is the CMM. All the task are supervised by CMM. Any in coherency between CMM and the NI can cause problems to appear.

1 The first step for troubleshooting problems with the switch is to look at the overall general health of the

switch.

OmniSwitch 7700/7800/8800

Verify that all of the modules in the chassis are up and operational, using the command:

-> show module status

Operational Firmware Slot Status Admin-Status Rev MAC

------+-------------+------------+---------+----------------CMM-A UP POWER ON 36 00:d0:95:6b:09:40

NI-1 UP POWER ON 5 00:d0:95:6b:22:5c

NI-3 UP POWER ON 5 00:d0:95:6b:23:2e

NI-5 UP POWER ON 5 00:d0:95:6b:3a:20

OmniSwitch 6624/6648

If the switch is having any problems the first place to look for is the CMM. All the task are supervised by CMM. Any in coherency between CMM and the NI can cause problems to appear. For OS-6600 with 8 units stacked together, the CMM will be:

• Primary

• Secondary

• Idle

The switch with the lowest ID will become the primary CMM.

The first step for troubleshooting problems with the switch is to look at the overall general health of the switch.

Verify that all of the modules in the chassis are up and operational, using the command:

-> show module status Operational Firmware

Slot Status Admin-Status Rev MAC

------+-------------+------------+---------+-----------------

CMM-1 UP POWER ON N/A 00:d0:95:84:4b:d2

NI-5 UP POWER ON N/A 00:d0:95:84:39:be

NI-6 UP POWER ON N/A 00:d0:95:84:4a:90

NI-7 UP POWER ON N/A 00:d0:95:84:39:f4

NI-8 UP POWER ON N/A 00:d0:95:84:3c:44

OmniSwitch 6600 with 8 stackable switches show up. Notice that the switch with ID 1 is the primary CMM and the switch with ID of 2 is the secondary. All the switch also show up as NI because each switch has a CPU and is also a NI.

To verify the stacking topology, use the following command:

-> show stack topology

Link A Link A Link A Link B Link B Link B

NI Role State RemoteNI RemoteLink State RemoteNI RemoteLink

---+-----------+---------+---------+-----------+---------+---------+----------

1 PRIMARY ACTIVE 8 51 ACTIVE 2 52 2 SECONDARY ACTIVE 3 27 ACTIVE 1 52 3 IDLE ACTIVE 2 51 ACTIVE 4 52 4 IDLE ACTIVE 5 51 ACTIVE 3 28 5 IDLE ACTIVE 4 51 ACTIVE 6 52 6 IDLE ACTIVE 7 51 ACTIVE 5 52 7 IDLE ACTIVE 6 51 ACTIVE 8 52 8 IDLE ACTIVE 1 51 ACTIVE 7 2

The above command shows the stacking topology. Switch 1 is the primary connected to Switch 8 on port 51 and Switch 2 on port 52. The state of CPUs for all the switches in the stack is shown by the output of this command.

2 Verify the power supply (or supplies).

OmniSwitch 7700/7800/8800

Omni Switch 7/8XXX has build-in mechanism to power off the modules if the power supply is not enough. Switching off a power supply in a chassis which does not have redundant power supply will result in power off of the modules. Make sure that there is no power involvement.

Check the power supply status, using the command:

-> show power supply 1

Module in slot PS-1

3 Verify the CPU utilization.

OmniSwitch 6624/6648 and 7700/7800/8800

The CPU utilization of CMM can be viewed by using the command:

-> show health

* - current value exceeds threshold

Device Min 1 Hr 1 Hr Resources Limit Curr Avg Avg Max

----------------+-------+-----+------+-----+-----+-------

Receive 80 00 00 00 0 Transmit/Receive 80 00 00 00 00 Memory 80 43 43 43 43 Cpu 80 02 06 05 07 Temperature Cmm 50 38 37 37 37 Temperature Cmm Cpu 50 32 32 31 32

The above command shows the receive, transmit/receive, memory, CPU, temperature CMM and temperature CMM CPU statistics for current, 1 minimum average, 1 hour average and 1 hour maximum. All the values should be within the threshold. Anything above the threshold depicts that some abnormal behavior. Normally 1 hour average maximum might be high if the switch was booted up in the last hour but it should be fairly steady during normal operation.

If none of the above are above the threshold then the next step is to try to isolate the problem to a particular NI. Due to the distributed architecture every NI has it own CPU to perform some operations locally. It is possible that a particular NI might be at high CPU utilization at a time when other NI as well as the CPU are within the thresholds.

If none of the above are above the threshold then the next step is to try to isolate the problem to a particular NI (or a switch within an OmniSwitch 6624/6648 stack) with the show health slot_number CLI command:

-> show health 5

* - current value exceeds threshold

Slot 05 1 Min 1 Hr 1 Hr Resources Limit Curr Avg Avg Max

----------------+-------+-----+------+-----+-----+-------

Receive 80 01 01 01 01 Transmit/Receive 80 01 01 01 01 Memory 80 39 39 39 39 Cpu 80 21 22 21 24

The principle for the health of an NI is the same as for CMM.

page 1-6 OmniSwitch Troubleshooting Guide September 2005

Troubleshooting the Switch System Troubleshooting System for OS-6624/6648 and OS-7/8XXX

The average on one minute is calculated from the average of 12 samples. Each sample is an average of the CPU utilization during 5 seconds. Those values are stored in a table. The current minute (1 Min Avg or “min”) displays the average of the last 12 samples.

Every 60 seconds the average of the 12 samples is recorded into the average value for this minute. Those values are stored in a form of 60 samples which represent one hour.

Most probably one of the above would help to localize the problem to a particular NI or to CMM. For more details see, Section “Monitoring Switch Health” in the chapter titled “Diagnosing Switch Problems” in the appropriate OmniSwitch Network Configuration Guide.

4 Check the switch log.

OmniSwitch 6624/6648 and 7700/7800/8800

Now, one of the most important things to check is the switch log. Switch log would contain the error messages depending on the settings of the log levels and applications configured to generate error messages. Default settings of the log switch log can be view using the command:

-> show swlog

Switch Logging is:

- INITIALIZED

- RUNNING

Log Device(s)

----------------

flash console

Only Applications not at the level ‘info’ (6) are shown Application ID Level

----------------------------

CHASSIS (64) debug3 (9)

By default, log devices are set to be flash and console. This can be changed and specific log servers can be used to log the messages, please refer to the Switch Management Guide for further details. The application trace level is set for ‘info’. Any error messages or informational messages would be logged in the switch log.

Switch log should be viewed to see if any errors messages were generated by the switch. The command to use is:

-> show log swlog

Displaying file contents for 'swlog2.log' FILEID: fileName[swlog2.log], endPtr[32]

configSize[64000], currentSize[64000], mode[2] Displaying file contents for 'swlog1.log' FILEID: fileName[swlog1.log], endPtr[395]

configSize[64000], currentSize[64000], mode[1]

The log message are kept in two log files: swlog1.log and swlog2.log in flash. In the above example, log messages show that some GBICs were extracted and inserted at a particular time. In addition, the switch was rebooted. This information helps to relate the time of the problem together with the events happening at the switch. In addition, it also provides an idea about if the source of the problem was external or internal to the switch.

If the log messages do not show enough information then they can be changed for specific applications to a higher log level or for all the applications running in the switch. For setting up different log levels in switch log, please refer to the “Using Switch Logging” chapter in the appropriate OmniSwitch Network

Configuration Guide.

If the switch is running in redundant configuration make sure that the two CMMs are completely synchronized. This can be done using the command:

-> show running-directory Running CMM : PRIMARY, Running configuration : WORKING, Certify/Restore Status : CERTIFIED, Synchronization Status : SYNCHRONIZED

If the two CMMs are not synchronized and the problem leads to the failure of Primary CMM then it will result in re-initialization of all of the modules. If the two CMMs are properly synchronized and primary CMM failed, the take over mechanism will be transparent to the end user. So, for complete redundancy keep the two CMMs synchronized.

Look for any post-mortem dump files that may be created due to the problem with the switch. Post Mortem Dump files have an extension of *.dmp and are created in /flash directory of the CMM (be sure to check the secondary CMM, if running in redundant mode). System dump files are normally named as “cs_system.dmp”, Memory related dump files are normally created as “MemMon000.dmp” and NI related dump files are named as “SloXSliYver1.dmp”, where X is the slot number and Y is the slice number.

The creation of a dump file indicates a problem with the switch. System related dump files can be viewed through CLI but other dump files cannot. For system related dump files use the command:

-> show log pmd cs_system.pmd

Capture the output of this command. In addition, if there are any dump files created in the switch, they should be downloaded through FTP to forward them to technical support. Technical Support can have them analyzed to find the source of the problem.

page 1-8 OmniSwitch Troubleshooting Guide September 2005

Troubleshooting the Switch System Advanced Troubleshooting

Advanced Troubleshooting

One level of switch logging is stored in the two log files located in the /flash directory. There is another low level debug that can be enabled and used for diagnosing the problems. This debug is known as “systrace”, meaning system trace. The information in this trace is stored in NVRAM on the CMM, so it is valid until powered off. Soft reboot of the switch will retain the trace information but powering off the switch will result in loosing all of the information. This is less CMM intensive so can be used to collect all the background information about the different tasks running in the switch.

The command to look at the default settings for systrace is

-> debug systrace show sysTrace is:

- INITIALIZED

- RUNNING

- configured to TRACE CALLERS

- configured to NOT WATCH on stdout

All Applications have their trace level set to level ’info’ (6)

Systrace is set for the level of “info” for all the applications. Any application with trace level other than 6 is displayed in the above command output. Notice that it is initialized by default and is running in the background. By default it is configured not to display messages on the console. The purpose of systrace is to track all the system processes called and the caller.

Application log levels can be changed and specific applications can also be set for the logging purposes. The commands are similar to switch log.

-> debug systrace appid ?

This information is useful to analyze the different processes taking place in the switch.

Other useful command to use in case of problem is:

-> show tech-support

This command captures all of the information from the chassis, including the hardware information, configuration, software release active and some other statistics about the number of buffers being used at the time of the use of command. The output of the command is saved in /flash as “tech_support.log”. Other variation of this command is:

-> show tech-support layer2

This command collects Layer 2 data only.

-> show tech-support layer3

This command collects Layer 3 data only.
