Procedure for capturing Show tech support on TFTP server


Show tech-support

This command is used to display technical support information which can be used in troubleshooting the router.The show tech-support command displays the output of a number of show commands at once. The output from this command varies depending on the platform and configuration.
This command can generate a very large amount of output. So the ideal way is to redirect the output to a file on the tftp which can be handy if the logs needs to be provided to the technical support representative.


Process for executing the command and redirecting it to tftp server.

Following steps needs to be followed in order to redirect the show tech-support output to the tftp folder.

  1. Log on to the FTP Server(tftp server ip)


  1. Create a file on the ftp server on which you want the logs to be taken.

    • Create a file on desktop without any extension.
    • Copy this file and paste on the ftp server.



  1. Log on to the Router and execute the below mentioned command.

Show tech-support | redirect <disk>:<ROUTER_NAME-DD-MM-YY-Desc>

NOTE:make sure that Disk has enough space to capture the show-tech command output.
Also the filename crated on the router and the ftp server be same.






  1. Once the output is saved in the disk, we need to copy the file from disk to the ftp server.

PE3-MLM-EU#copy disk0: ROUTER_NAME-DD-MM-YY-Desc tftp:
Address or name of remote host []? tftp server ip
Destination filename [ROUTER_NAME-DD-MM-YY-Desc]?

The Show tech is copied and same information can be accessed:

File Name: ROUTER-TECH-260309-desc
