Description (partial)

ssh server in vEdge and other sdwan devices is hardcoded with a client timeout of 4x15 seconds.
This implies that every command output needs to complete within one minute.
Otherwise the ssh server terminates the connection.

The combination of ssh output size, network latency or issues at ssh client side causes delays and It takes more than a minute to deliver the ssh data to client.
