Frequently Asked Questions

  • What is the analyzer?
  • The analyzer is a tool to check network switches or routers. It's very useful in combination with software updates, configuration changes, network issues or just to check if the hardware and software is ok. As input data the show tech output is used.
  • What about the security of the data and the analysis results?
  • We are taking care to protect your data. The data transfer is encrypted. The analyses are visible only from your IP address. If a company proxy is used only employees have got access. The analysis website is protected by a 48 digit alphanumeric random code. Analyses (all data) will be automatically deleted after 3 hours from our server. The user has the option to delete all data anytime by himself. For that there is a button at the end of the analysis document.
  • Do I need network know-how to work with the analyzer?
  • The analyzer shows results in easy understandable form and indicates problems visibly, so that also a layman can directly recognize them. To use the full potential of the analyzer network know-how is required.  
  • How long the analyzer results will be available online?
  • Three hours. After that all data will be deleted automatically from our server.
  • How long does it take to get the results from the analyzer?
  • It will take only few seconds.
  • How to get the show tech output for the analyzer?
  • Connect to the device (e.g. via serial, telnet or ssh) and log the output of the following command in enabled mode: 
    sh tech
  • How to disable the --More-- breaks during the sh tech output?
    terminal length 0 or no pager or sh tech | no-more
  • How to split a log file that contains more than one show tech output?
  • This can be done e.g. with the following Linux command: 
    csplit log.txt '/# sh[[:alnum:]]* tec/' {*}
    This command will generate from the file log.txt single show tech output files like:
    xx00 
    xx01
    xx02

    Hint: The first generated file numbered with 00 can be normally ignored.
    To influence the name of the output file names you can use:
    1. The prefix parameter:  -f sh-tech-
    2. The suffix parameter:   -b %02d.txt
