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) that is 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 the admin, assigns an IP address to the management port, and defines a default route to a network gateway. 1. Provide power to the switch (Cabling the Switch). 2. Connect the console port to a PC (Connecting Serial and Management Cables). 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 be fully functional after a valid startup-config is downloaded from a remote system or Zero Touch Provisioning is canceled. To cancel Zero Touch Provisioning, log in as an admin and type 'zerotouch cancel' in the CLI. localhost login: 3. Log into the switch by typing admin at the login prompt. localhost login: admin 4. Cancel ZTP mode by typing zerotouch cancel. Important: This step initiates a switch reboot. localhost> zerotouch cancel 5. After the switch boots, log into the switch again by typing admin at the login prompt. Arista EOS localhost login: admin Last login: Fri Mar 15 13:17:13 on console 6. Enter global configuration mode. localhost> enable localhost# config

1. Assign a password to the admin username with the username secret command. localhost(config)# username admin secret pxq123 8. Configure a default route to the network gateway. localhost(config)# interface management 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 the management port IP address is configured, select this command to access the switch from a host using the address configured in Step 9: ssh admin@192.0.2.8 Refer to the Arista Networks User Manual for complete switch configuration information.
