Identifying a Failed Line Card
This section expains how to identify a failed line card when getting a loopback failure.
Before you begin
Collect the Logs Location file of the On-Demand TechSupport policy for the fabric node. To initiate the collection:
Download the the Logs Location file of the On-Demand TechSupport policy for the fabric node. To download the Logs Location file:
Inside the Logs Location file, go to the /var/sysmgr/tmp_logs/ directory and unzip the svc_ifc_techsup_nxos.tar file.
Run zgrep "fclc-conn failed" show-tech-sup-output.gz | less.
Power cycle the currently failed fabric cards and ensure the fabric cards come online.
If the fabric cards fail to come online, or after the fabric cards go offline again, immediately collect the diag_port_lb.log file and send the file to the TAC team. The diag_port_lb.log file is located in the /var/sysmgr/tmp_logs/ directory of the Logs Location file.
