Configuring the Arista NDR Platform

 

After the appliances are physically installed and cabled up, the next step is software configuration of the individual Arista NDR appliances, which, after configured, will combine to become the Arista NDR Platform:
  1. Connecting to the Admin CLI
  2. Configuring the Appliance
  3. Verifying the Configuration

Connecting to the Admin CLI

 

You can access the CLI by physically connecting a monitor and a keyboard to the Arista NDR appliance SKU. The following screen is displayed:

Figure 1. Command Prompt Window
Note: Enter the username as admin and the password provided by the Arista technical support.

Configuring the Appliance

 

Configure the following networking parameters in Arista NDR appliances:
Note: If configuring all networking parameters simultaneously, you can run the apply and reboot commands at the end of all configurations instead of running them for each.

Configuring the Management Interface

 

Perform the following steps to configure the management interface:

  1. Enter the set interface static <ip> <netmask> <default gateway> where specified variables denote the following values:
    • <ip> - IP address of the management interface
    • <netmask> - Netmask of the network (for example, 255.255.255.0)
    • <default gateway> - Default gateway of the network
    The CLI displays the following prompt: 
    Applying network settings now might cause the network to disconnect.
If you do not apply network settings now, network settings will
take effect only after running "apply" and "reboot"
Do you want to apply network settings now? (y/n)
  2. Enter y.
  3. Enter the apply command to apply the changes.
  4. If no further configuration changes are required, enter the reboot command to restart the device.
     

Configuring DNS

 

You must set up Domain Name Servers (DNS) in Arista NDR appliances to use hostname instead of IP addresses. Perform the following steps to configure DNS:
  1. Enter the set dns nameservers command.
    An interactive prompt will ask for primary and secondary servers.
  2. Enter the primary and secondary DNS.
  3. Enter the apply command to apply the changes.
  4. If no further configuration changes are required, enter the reboot command to restart the device.

Configuring NTP

 

You must configure the Network Time Protocol (NTP) in all of your Arista NDR appliances to ensure the accuracy of the appliance clock. Perform the following steps to configure NTP:
  1. Enter the set ntp servers command.
    An interactive prompt will ask for primary and secondary servers.
  2. Enter the primary and secondary servers.
  3. Enter the apply command to apply the changes.
  4. If no further configuration changes are required, enter the reboot command to restart the device.
     

Configuring Proxy

 

Arista NDR appliances support outgoing connection using the customer's proxy (without SSL interception). Perform the following steps to configure proxy for outgoing connections:
  1. Enter the set proxy servers command.
  2. Enter the required details when an interactive prompt asks for the following information:
    • Host: The IP address of the proxy server.
      Note: You may enter the hostname instead of the IP address if DNS already has been configured, applied, and the system was rebooted.
    • Port: The port of the proxy server
    • Username / Password: Enter the credentials if the proxy requires authentication.
  3. Enter the apply command to apply the changes.
  4. If no further configuration changes are required, enter the reboot command to restart the device.

Configuring IPMI Ethernet Interface

 

Arista NDR appliances provide a dedicated network interface for the Intelligent Platform Management Interface (IPMI). Perform the following steps to configure IPMI:
  1. Enter the set ipmi config command.
  2. Enter the required details when an interactive prompt asks for the following information:
    • IPMI Interface Mode (static or dhcp): Sets the interface to either DHCP or Static mode.
      Note: We recommend setting the interface to static mode.
    • IP: The static IP address of the interface.
    • Subnet Mask: The subnet mask of the network. For example, 255.255.255.0
    • Default Gateway: The default gateway of the network
    • Would you like to change the ipmi admin password: Enter y to configure the IPMI password, else enter n.
      Note:
      • The default password is printed on a label on the appliance.
      • The password can be shared if it is configured by the installation team.
      • The password should not exceed 20 characters and must contain numbers, uppercase letters, and symbols.
  3. Enter the apply command to apply the changes.
  4. If no further configuration changes are required, enter the reboot command to restart the device.

Verifying the Configuration

 

After the reboot is complete, log in to the CLI and enter the show networking command to verify the current configuration.

This command displays networking configuration settings for the management and IPMI Ethernet interfaces. Ensure that the network settings are correct.
