Configuring the Router

Arista routers ship from the factory in Zero Touch Provisioning (ZTP) mode. ZTP configures the router 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 router, 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 router 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 router, 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 router 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:

Connect the router to a power source (Cable the Router).

Note: Arista fixed routers take approximately 5 to 10 minutes to boot completely.
Connect the console port to a computer (Connecting Serial and Management Cables).
Log into the router by typing admin at the login prompt.
```
localhost login: admin
```
Cancel ZTP mode by typing zerotouch cancel

Important: This step initiates the router to reboot.
```
localhost> zerotouch cancel
```
After the router reboots, log into the router again by typing admin at the login prompt.
```

```
Enter global configuration mode.
```
localhost> enable 
localhost# config
```
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
```
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
```
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
```
Save the configuration by typing write memory or copy running-config startup-config.
```
localhost# copy running-config startup-config
```
When configuring the management port IP address, select the following command to access the router from a host using the address configured in Step 9.
```
ssh admin@192.0.2.8
```
