Steps to Perform Before Calling TAC

At some point, you might need to contact your technical support representative or Cisco TAC for some
additional assistance. This section outlines the steps that you should perform before you contact your next
level of support in order to reduce the amount of time spent resolving the issue.
To prepare for contacting your customer support representative, follow these steps:
1 Collect the system information and configuration. You should collect this information before and after
the issue has been resolved. Use one of the following three methods to gather this information:

Copying Files to or from Cisco NX-OS, page 91
Using Core Dumps, page 92
• Configure your Telnet or Secure Shell (SSH) application to log the screen output to a text file. Use
the terminal length 0 command and then use the show tech-support details command.
Note If certain show tech commands generate a large amount of data and occupy more disk
space, they can be stored in a compressed format. See the following example:
bash-4.2# time vsh -c " show tech-support platform-sdk" | gzip >
/bootflash/pltfm-tech.gz
• Use the tac-pac filename command to redirect the output of the show tech-support details command
to a file, and then gzip the file.
switch# tac-pac bootflash://showtech.switch1
• If you do not specify a filename, Cisco NX-OS creates the file as volatile:show_tech_out.gz. Copy
the file from the device using the procedure in
91.
