Overview
NetMRI appliances require static IP settings. However, during the initial startup, the DHCP client is enabled on the first network interface, and the assigned IP may be used for SSH connection. Configuration settings received from the DHCP server might also be set statically during server configuration. If you are using DHCP with NetMRI, record the IP address that is assigned to NetMRI, and then continue the configuration as described in Configuring NetMRI Using the Setup Wizard.
Initial NetMRI configuration can be carried out in a variety of ways, as listed below:
Run the
setuporserver configurecommand after establishing a connection to the server using SSH or the hypervisor consoleUse Cloud-Init
Configuring Network Settings for NetMRI Deployment
With the help of the CLI and Cloud-Init, you can set up the IPv4 and/or IPv6 address, Netmask/prefix, IPv4 and/or IPv6 gateway, DNS servers, DNS domain names, NTP server, time zone, server name, and database name.
Refer to the Configuring Server Options for more details.
The NetMRI image is initially released with one pre-installed network interface, but additional interfaces can be added for scanning purposes or HA. If a server has two connected network adapters, the SCAN interface can be configured during the initial setup. However, please note that subinterfaces cannot be configured through this method.
In cases where NetMRI is deployed to a private (OpenStack) or public (AWS) cloud with DHCP enabled by default and IP addresses are assigned automatically to instances, you should assign the IP address as MGMT and configure it statically.
Configuring SCAN Interfaces for DHCP
The SCAN interfaces will not receive an IP address during initial setup because the DHCP client is only enabled for the MGMT interface. In such cases, you will need to manually determine the IP address assigned by the DHCP server. For AWS or OpenStack, you can check this in the instance description, network section, or ENI description. Please note that NetMRI currently does not support DHCP clients for the SCAN interface.

Configuring Server Options
If you are configuring server options, verify the following:
IPv4 Address - public or private* IPv4 address
* It should be noted that IP addresses starting with 169.254.1.0/24 are not permitted.IPv4 Network mask - IPv4 subnet network
IPv4 Gateway - public or private IPv4 address from the same subnet as IPv4 Address
IPv6 Address - public or private IPv6 address
IPv6 Prefix - IPv6 prefix length
IPv6 Gateway - both a public and private IPv6 address from the same subnet
DNS Server - IPv4 or IPv6 address
DNS Domain Name - Allows up to 253 symbols (including the server’s name), case-sensitive alphabetic letters, numbers, hyphens (-), and dots (.); each label cannot begin or end with a hyphen symbol
Server Name - Allows up to 63 symbols, including case-insensitive alphabet letters, numbers, and hyphens (-)
NTP Server - IPv4 or IPv6 address or domain name
Time Zone - Allow any of the suggested CLI configurations to support any TZ listed in the IANA database (version 2023c) with cloud-init
Database Name - Allow case-insensitive alphabetic characters, digits, dots, hyphens, underscores, and spaces, but do not permit them to end with spaces ( )
Note: It is not possible to configure the same IP address for each interface.
Note: If a relevant IP address was entered, IPv4 netmask, IPv6 prefix, IPv4 gateway, and IPv6 gateway are necessary.
Note: The MGMT interface requires at least one DNS server and one DNS domain name.
Note: Gateways on links are not supported; therefore, gateways must be from the same subnet and cannot be NetMRI IPs.
Understanding DNS Servers and Domain Names
The DNS settings set up for the MGMT interface will be applied globally. DNS servers for each interface will respond to DNS queries only when the domain name in the query matches the domain name configured for that specific interface; otherwise, the global DNS servers will be used.
Management Interface IP Addresses
Upon the initial launch, NetMRI will attempt to acquire an IP address for the MGMT interface from the DHCP server if it is accessible within the network. If DHCP is not available, you can use the default 169.254.1.1 IP address for the initial connection and initial setup. Please note that the 169.254.1.1 IPv4 address is preconfigured as an additional MGMT IP and is not editable.
To connect locally, you can configure any IP within the 169.254.1.0/24 range on your device, such as a Windows or Linux machine, provided that the NIC is within the same broadcast domain as NetMRI. Furthermore, connecting through this IP address or via the hypervisor console is necessary if you intend to change the MGMT IP address through CLI. Failure to do so may result in an SSH connection drop while new settings are applied, potentially causing some settings to be missed.
