Using Core Dumps - Cisco Nexus 9000 Series Troubleshooting Manual

Before Contacting Technical Support

Using Core Dumps

Using Core Dumps
Core dumps contain detailed information about the system and software status prior to a crash. Use core dumps
in situations where unknown problems exist. You can send core dumps to a TFTP server or to a Flash card
in slot0: of the local system. You should set up your system to generate core dumps under the instruction of
your technical support representative. Core dumps are decoded by technical support engineers.
Set up core dumps to go to a TFTP server so that you can e-mail these core dumps directly to your technical
support representative.
Use the system cores command to set up core dumps on your system as follows:
switch# system cores tftp://10.91.51.200/jsmith_cores
switch# show system cores
Cores are transferred to tftp://10.91.51.200/jsmith_cores
The filename (indicated by jsmith_cores) must exist in the TFTP server directory.
