3 1) Introduction The main purpose of this document is to explain how to collect the main log files on an Alcatel-Lucent switch. Besides, we will see which major information we need to gather before filling incident reports. Many files are present in a switch: Boot.cfg (vcboot.cfg,vcsetup.cfg in case of Virtual Chassis): Configuration file. Tech_support log files: Contain the technical information about the switch. Swlog files: Contain the logs, the events. Command.log: Logs of the commands used on the switch. PMD files: Generated when the switch is failing. 2/20

4 2) How to collect the boot.cfg (or vcboot.cfg and vcsetup.cfg)? 1. To collect the boot.cfg file, you have to be logged in to the switch. By default, Login: admin Password: switch Once you are logged in to the switch, you have to go in the folder called working or the folder running the current configuration cd working (or the name of the folder running the configuration. This folder s name is written there): Then, type ls working to see the file in the folder. 3/20

5 Above, we see the file called boot.cfg. Once you did this, refer to the appendix How to get back a file from a switch? 4/20

6 3) How to gather Tech_support log files? To collect those files, you have to create them before using the commands: show tech-support, show tech-support layer2, show tech-support layer 3, show tech_support eng. Then, go to /flash and use the command ls to check the files creation. Once you did this, refer to the appendix How to get back a file from a switch? 5/20

7 4) How to collect swlog1.log and swlog2.log, command.log, pmd files? Those files are present in the folder /flash. To collect their, you have to read the appendix II: How to get back a file from a switch? 6/20

8 5) How to capture command outputs? We need others information before opening PR or SR. Use those commands: Ls lr Show transceivers Show configuration status Show log swlog Show command-log (if command-log is enabled) Show user Show snmp statistics Show mac-learning Boardinfo 7/20

9 Type all of these commands on the switch. To collect the command outputs, refer to the appendix How to log a terminal session? 8/20

10 6) The network drawing Draw a network diagram. In this diagram, you have to notify the sub network, the IP addresses and the mask. Specify the network protocols running on your network. Be as specific as possible. e.g.: Network side SR 7750 OS 6850E-U24X OS 6400-U24 1/1 SFP 1/1 SFP Stack cable 2/1 SFP 2/1 SFP Linkagg Stack cable Svlan:vlan 1874:2520 Svlan:vlan 1874:2520 9/20

11 7) Problem description Explain precisely what happened to the switch. Give as much information as possible about the configuration running on the switch, about the protocols Specify the code versions running on the switches and specify the switches types. Explain the circumstances during which the incident appear and the conditions to reproduce the issue. Describe which ports are used in the configuration. Be as much specific as possible and give a lot of details. It will help. 10/20

12 8) OmniSwhitch in a Redundant Configuration Virtual Chassis (VC) is a network virtualization technology offered in OmniSwitch 6900 and 10K. With VC, you can assemble chassis to form a single logical form factor with a unified control and configuration file, as well as a single OS instance that operates across the entire VC. One chassis will be Master, the primary one, then a secondary etc This section applies to the OmniSwitch chassis 10K with dual CMMs and OmniSwitch 6900 working on redundant configuration. The goal is to gather as much information as possible about the redundant CMM (10K) and the secondary unit (6900). If a physical access to the console port of the secondary unit is available, please provide the output of the following commands when logged in on that port: show microcode loaded show microcode certified show system show hardware-info show running-directory ls r show log swlog 11/20

13 In addition to this information, it is necessary to have the original log files and possible dump files present on a secondary and idle units. Please execute the following commands: rls x / rls x /working rls x /certified rcp x:swlog1.log swlog1.x.log rcp x:swlog2.log swlog2.x.log rcp x:dumpf.pmd dump.x.pmd dump.pmd refers to any file with a pmd or dmp extension. x refers to the number of all the units except the primary s one. Refer to the appendix I: How to log terminal sessions? to gather information. 12/20

14 Appendix I: How to log terminal sessions? We will use the terminal emulator called putty. This is the link to download putty: Once you have downloaded it, open it. We are using console port, that s why the connection type is Serial. Select Serial. 13/20

15 You should have this window: Now, we configure Putty to log the session. It will save all the commands we typed on the switch. Go in the sub category named Logging : 14/20

16 In the part Session logging, select All session output and choose the name of your log file and the place you want to save it. Now, go back in the category Session and click on Open to launch the session. 15/20

17 A black window should appear and push the Enter and type the login and the password: Now check your log file (I chose the Desktop as the save place). You can see the log of your authentication. The logging is working. 16/20

18 Appendix II: How to gather a file from a switch? If you don t already have one, create an IP interface on the switch: ip interface vlan1 address /24 vlan 1 By default, vlan 1 is on all the switch ports. Else use vlan 1 members port X/Y to assign the vlan 1 to a specific port. (X refers to the slot, Y to the port) We can see the vlan1 interface created on the switch. On OmniSwitch 6900 or 10K, you can use the EMP Interface. Must be connected to the associated CMM s console port before attempting to change IP address information using the modify boot parameters command as shown below: If you use the commit system command only, changes will note be saved to the switch s non-volatile memory and will be lost if the switch is rebooted. On your computer, use an interface and configure an IP address in the same 17/20

19 sub network than the switch /24 Once this is done, plug a cable between the port in vlan 1 on the switch and the computer network interface. We will use FTP to transfer the boot.cfg file from the switch to the computer. To check connectivity between the two interfaces, use the command show ip interface. Interface status is Up ; there is connectivity between the two interfaces. Activate ftp on the switch by using the command aaa authentication default local. 18/20

20 Now, we will use an FTP software called WS_FTP95 to collect the boot.cfg. You can use other software like FileZilla to do it. This is the configuration you have to use after the WS_FTp95 launching: The Host Name/Address is the most important field. It corresponds to the IP address configured previously on the switch. (By default) User ID: admin Password: switch Once this is done, if you configured correctly your FTP software, you have this: On the left, you have the folder from your computer. On the right, you have the switch folders. The boot.cfg file is in the folder working. Go in this folder by double-clicking on its name. Then, on your computer, select a folder where you want to place the file using the button ChDir. 19/20

21 Then click on the arrow going to the left: You get back the file on the Desktop. 20/20
