Arista switches ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the switch
without user intervention by downloading a startup configuration file or a boot script from a location
specified by a DHCP server. To manually configure a switch, ZTP is bypassed. The initial configuration
provides one username (admin) accessible only through the console port because it has no password.
When bypassing ZTP, initial switch access requires logging in as admin, with no password, through the
console port. Then you can configure an admin password and other password protected usernames.
This manual configuration procedure cancels ZTP mode, logs into the switch, assigns a password to
admin, assigns an IP address to the management port, and defines a default route to a network
gateway.
Chapter 5
Step 1 Provide power to the switch (Section 4.1).
Step 2 Connect the console port to a PC (Section 4.3).
As the switch boots without a startup-config file, it displays the following through the console:
The device is in Zero Touch Provisioning mode and is attempting to
download the startup-config from a remote system. The device will not
be fully functional until either a valid startup-config is downloaded
from a remote system or Zero Touch Provisioning is cancelled. To cancel
Zero Touch Provisioning, login as admin and type 'zerotouch cancel'
at the CLI.
localhost login:
Step 3 Log into the switch by typing admin at the login prompt.
localhost login:admin
Step 4 Cancel ZTP mode by typing zerotouch cancel. IMPORTANT: This step initiates a switch
reboot.
