Description

For Juniper Networks EX/QFX Series switches, you might encounter issues with port bounces or with remote shell access.

Symptoms

From the GUI, the port bounce screen says unable to open netconf session, or the remote shell with give a Connection Closed banner right after launching. From the logs you might see the switch is unable to open new SSH sessions.

Solution

The following configuration needs to be removed or tweaked as it will cause Mist management issues: 
set system services ssh max-sessions-per-connection 2
set system services ssh client-alive-count-max 3
set system services ssh connection-limit 10
set system services ssh rate-limit 5
