Configuring the Device

Arista devices ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the device 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 device, 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 device 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 device, 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 device 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 device to a power source (Cable the Device).
    Note: Arista fixed devices 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 device by typing admin at the login prompt. 
    localhost login: admin

     

  4. Cancel ZTP mode by typing zerotouch cancel
    Important: This step initiates the device to reboot.
    localhost> zerotouch cancel

     

  5. After the device reboots, log into the device again by typing admin at the login prompt.

  6. Enter global configuration mode. 
    localhost>enable localhost#config

     

  7. Assign a password to the admin username using the username secret command. In this example, the assigned password is "pxq123". 
    localhost(config)#username admin secret pxq123

     

  8. Configure a default route to the network gateway. In this example, the default route is 192.0.2.1. 
    localhost(config)#ip route 0.0.0.0/0 192.0.2.1

     

  9. Assign an IP address to an Ethernet management port. In this example, the IP address is 192.0.2.8/24. 
    localhost(config)#interface management 1/1
localhost(config-if-Ma1/1)#ip address 192.0.2.8/24

     

  10. Save the configuration by typing write memory or copy running-config startup-config. 
    localhost#copy running-config startup-config

     

  11. When configuring the management port IP address, select the following command to access the device from a host using the address configured in Step 9. 
    ssh admin@192.0.2.8
