Operating Mode Button

This section discusses the functionality of the mode button located on the front panel of the switch.

 

Figure 1. Mode Button States

 

The mode button port LEDs will transition to different modes as listed below when the user presses the mode button for less than 2 seconds, and the same is indicated by the corresponding mode status LED.

  • Normal Mode

  • PoE Mode

  • Speed Mode

     

In addition to controlling the port/mode LEDs, the button can trigger other actions, including a hard reset and a factory reset. To access these actions, it is required to long-press the button as shown in the Figure 1 - Mode Button States.

  • Entering Reset States:

    If you select and hold the button for more than 2 seconds, all the 3 mode status LEDs will flash to indicate the transition from regular operating states to reset states. If the button is released before 5 seconds, no action will occur, and the system will return to its previous mode (normal, PoE, or link speed).

     

  • Hard Reset:

    If you select and hold the button for about 5 to 15 seconds, it will trigger a hard reset of the system 2 seconds later.

     

  • Factory Reset:

    If you select and hold the button for about 15 seconds or longer, it will trigger a hard reset of the system 2 seconds later. In addition, the system will also trigger factory reset on system configuration.

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) 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 admin, assigns an IP address to the management port, and defines a default route to a network gateway.

  1. Provide power to the switch (Connecting Power Cables).
  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 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:

     

  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

     

  7. 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)# ip route 0.0.0.0/0 192.0.2.1

     

  9. Assign an IP address (192.0.2.8/24 in this example) to an Ethernet management port. 
    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, 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 complete switch configuration information.

    Note: The device configuration does not stream voltage and current data.
