Quick Start Guide: 720XP Series 1 RU-Gen 3 Cognitive Campus Switches 15 Connecting Serial and Management Cables Chapter 4: Cabling the Switch 16 Quick Start Guide: 720XP Series 1 RU-Gen 3 Cognitive Campus Switches Chapter 5 Configuring the Switch 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. 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. localhost>zerotouch cancel Step 5 After the switch boots, log into the switch again by typing admin at the login prompt.
