The network settings, including IP address, subnet mask, and default gateway, and the Domain Name Service (DNS) server addresses, are defined manually.

There are two management Ethernet interfaces on the NDR: Eth0 and Eth1. Eth0 is configured for management, which allows a user to SSH to the device and use a browser to interact with the NDR. Eth1 is used for internal communications between the NDR and Packet Capture. To change network settings, use the CLI.

Important

Trellix highly recommends using the CLI to modify your NDR appliance configuration settings. Trellix does not provide technical support for configuration changes made using the shell. (DOC-958)

To manually configure the management interface, you must use the Eth1 interface.

Configuring Eth0 and Eth1

To configure Eth0 and Eth1:

  1. Log in to the NDR as npadmin using the NDR IP address or FQDN. For example:

    $ ssh npadmin@10.1.0.1

    $ ssh npadmin@exampleFQDN

  2. Enter privileged mode:

    npadmin@ia> enable

  3. Enter the npadmin password. The password can be 5 to 24 characters long.

    [sudo] password for npadmin: <password>

  4. Enter configuration mode:

    npadmin@ia# configure system

  5. Enter the network settings:

    hostname # network

  6. To set the Eth0, type 7. When prompted, enter the address for eth0.

  7. To set the Eth1, type 8. When prompted, enter the address for eth 1.

  8. Type q to save your settings and exit.

  9. Type y or n to confirm your changes.

  10. Type y to restart the network.

Configuring the hostname
