Configuring the Switch
Arista fixed configuration switches ship from the factory in Zero Touch Provisioning (ZTP) mode, which configures a switch without user intervention by downloading a startup configuration file or a boot script from a location specified by a DHCP server.
If you are not using ZTP, the initial configuration provides one username, admin, that is not assigned a password. When using any username without a password, you can only log into the switch through the console port. After assigning a password to the admin username, you can log into the switch through any port.
This procedure performs the following initial configuration tasks:
• cancels ZTP mode.
• assigns a password to the admin username.
• assigns an IP address to the Ethernet management port.
• defines a default route to a network gateway.
Step 1 Provide power to the switch, as described in Section 4.1
Step 2 Connect the switch to a PC with a RJ-45 serial adapter cable, as described in Section 4.2.
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 at the localhost prompt.
localhost>zerotouch cancel
Step 5 After the switch boots log into the switch again by typing admin at the login prompt.

Step 6 Enter privileged EXEC mode by typing enable.
localhost>enable
Step 7 Enter global configuration mode by typing configure terminal (or config).
localhost#config
Step 8 Assign a password to the admin username with the username secret command.
localhost(config)#username admin secret pxq123
Step 9 Configure a default route to the network gateway.
localhost(config)#ip route 0.0.0.0/0 192.0.2.1
Step 10 Enter interface configuration mode by typing interface and the name of the management port.
localhost(config)#interface management 1
Step 11 Assign an IP address to the port by typing ip address, followed by the desired address.
localhost(config-if-Ma1)#ip address 192.0.2.8/24
This command assigns the ip address 192.0.2.8 to the management port.
Step 12 Exit by typing end at the interface configuration and global configuration prompts.
localhost(config-if-Ma1)#end
localhost(config)#end
Step 13 Save the configuration by typing write memory or copy running-config startup-config.
localhost#copy running-config startup-config
When the management port IP address is configured, use this command to access the switch from a host, using the address configured in step 11:
ssh admin@192.0.2.8
