  • Page 41: Chapter 5: Configuring The Modular Switch

    Chapter 5 Configuring the Modular 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.
  • Page 42 11. When the management port IP address is configured, use 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 the complete switch configuration information.
