This is self response.

I have found the following bug-id but this is about Catalyst 4000 series but it does not include Cat3650.

CSCud34951 - percent Failed to read thread information, returned 2010 on and39;show tech-support

% Failed to read thread information, returned 2010 on 'show tech-support

########

Hello 

When it repeats to do show tech-support on Cat3650 through telnet.

Then it shows the following unknown message through console port.

PC---->Cat3650 (telnet/console)

I have already investigated through CCO, release note or other search engine but there is not any related information.

Hello Masanobu,

Unknown log message when it repeats "show tech-support"

Try using the syntax

show tech-support [ brief ] [ save [ filename ] | save-uncompressed [ filename ] ]

Parameters

brief
    Displays a summary of show version, show configuration, show interfaces, show ip route, and show log commands.
save
    Saves the support information to a compressed (.gz) file. The file name takes the format hostname tech-support timestamp gz, where hostname is the host name configured for the Vyatta device and timestamp is the time the file was saved in the format YYYY-MM-DD-hhmmss.

    For local files, a rotation mechanism limits the number of output files to 100; that is, creating a file after the first 100 files causes the oldest file to be deleted.
save-uncompressed
    Saves the support information to an uncompressed file. The file name takes the format hostname tech-support timestamp, where hostname is the host name configured for the Vyatta device and timestamp is the time the file was saved in the format YYYY-MM-DD-hhmmss.

    For local files, a rotation mechanism limits the number of output files to 100; that is, creating a file after the first 100 files causes the oldest file to be deleted.
filename
    The name of a file to which to save the support information. Refer to “Usage Guidelines” for details.

To better manage this output, you can redirect the output to a file (for example, show tech-support > filename ) in the local writable storage file system or the remote file system.

You can use one of the following redirection methods:

  • > filename —Redirects the output to a file.
  • >> filename —Redirects the output to a file in append mode.

Show tech-support is just a consolidated file of all the show commands that a specific device holds.

You can use simple show commands as an alternative for it

Hello Jkilleda,

 

Thank you very much, I appreciate if I can make sure of this output log.

So the conclusion is just cosmetic it can be ignored right?

 

Best Regards,

Masanobu Hiyoshi
