Configuring the Router

Arista routers ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the router without

user intervention by downloading a startup configuration file or a boot script from a location specified by a

DHCP server.

To manually configure an Arista router, bypass ZTP. The initial configuration provides one username (admin)

that is accessible only through the console port because it does not have a password.

When bypassing ZTP, access the router by logging in as admin, with no password, through the console port.

Then, you can configure a password for admin and other password-protected usernames.

The manual configuration procedure described below cancels ZTP mode, logs into the router, assigns a

password to the admin, assigns an IP address to the management port, and defines a default route to a

network gateway.

As the router 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.

1. Connect the router to a power source (Cable the Router).

Note: Arista fixed routers take approximately 5 to 10 minutes to boot completely.

2. Connect the console port to a computer (Connecting Serial and Management Cables).

3. Log into the router by typing

admin at the login prompt.

localhost login:

admin

4. Cancel ZTP mode by typing

zerotouch cancel

Important: This step initiates the router to reboot.
