We want and have to upgrade the Cores switch firmware to the Cisco recommended version.
Issue:
Our primary Core SW was blackholing the traffic due to an internal control plane issue or a bug issue, it happened twice and we had to reboot (cold reboot) the Core SWs (Primary and Backup).
There are no codes or logs that show an error.
Could you please recommend a suitable stable/conservative firmware version that should be loaded onto cores.
