When customers receive a new EX/QFX switch and power it on, it requests a login name and password.  For first-time Junos EX/QFX users this could be confusing as there is no password information included.  This article provides the default user ID and password information.

The initial login name and password on EX/QFX-series switches:

login: root
password: <no password>

The device is shipped with no password; simply press the enter key.

Note: For security reasons, create a password for the Root ID with the command :

root@Switch#set system root-authentication plain-text-password 

This is a mandatory step in order to be able to commit any configuration changes.

You can also use other types of authentication:

root@Switch# set system root-authentication ?
Possible completions:
+ apply-groups         Groups from which to inherit configuration data
+ apply-groups-except  Don't inherit configuration data from these groups
  encrypted-password   Encrypted password string
  load-key-file        File (URL) containing one or more ssh keys
  no-public-keys       Disables ssh public key based authentication
  plain-text-password  Prompt for plain text password (autoencrypted)
> ssh-dsa              Secure shell (ssh) DSA public key string
> ssh-ecdsa            Secure shell (ssh) ECDSA public key string
> ssh-rsa              Secure shell (ssh) RSA public key string
