I have vSZ running firmware version 126.96.36.199.959. Whenever we have needed to restart the cluster or restart our core, our switches show as offline in the controller, and we have only ever been able to reconnect them by running "manager disable" and "no manager disable" on each individual switch stack. Is there a way to have the switches automatically reconnect after disconnection, or do we need to run the commands each time?
SZ is not my area of expertise, but they should reconnect on their own to my knowledge. What is the model and code on the switch side? I would recommend 8095m for all 7xxx series being connected to SZ.
