Qfx Default Password 🆓 🎉

login: root Password: Press Enter at the password prompt. You are now logged in as root. If the switch has been configured for serial over LAN but the password was later cleared (e.g., via load factory-default ), the same blank password applies. 2.3 SSH – Not Enabled by Default Contrary to some misconceptions, SSH is not enabled out of the box. If you try:

loader> boot -s Enter full pathname of shell: /bin/sh # mount -t msdosfs /dev/da0s1 /mnt # vi /mnt/etc/master.passwd # (remove the password hash after root::) # reboot This is complex and requires physical or out-of-band console access. 6.1 Ansible and Default Passwords When using Ansible to initially provision QFX switches, never rely on a default blank password. Instead, use console-based first-time setup or pre-staged SSH keys via USB autoinstall. qfx default password

Introduction In the world of data center networking, Juniper’s QFX Series switches are ubiquitous. Designed for high-performance leaf-and-spine architectures, EVPN-VXLAN fabrics, and large-scale Layer 2/Layer 3 environments, these switches are powerful—but like all network devices, they begin their life in a vulnerable state. At the heart of that vulnerability lies a simple, often-overlooked question: What is the default password on a QFX switch? and large-scale Layer 2/Layer 3 environments

ssh root@<qfx-mgmt-ip> You will get Connection refused because the SSH service is disabled in factory state.
