We experience in a crash occurred on one of the switches 6K .
The Master CSS which is physically connected to the involved Core switch, changed its status to the Backup.
The Backup CSS which is physically connected to the other Core switch, that was working fine and had no problems, changed its status to the Master one, but was not able activate correctly the uplink to the main network.
Here some output of the CSS backup
Thanks for any helps
