NetMRI appliances require static IP settings. However, during the initial startup, the DHCP client is enabled on the first (MGMT) network interface, and the assigned IP may be used for the SSH connection. Configuration settings received from the DHCP server might may 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 to perform the configuration as described in Configuring NetMRI Using the Setup Wizard.
Initial The initial configuration of NetMRI configuration can be carried out in a variety in one of two ways, as listed below:
Run By running the setup or the
server configurecommand after establishing a connection to the server by using SSH or the hypervisor consoleUse CloudBy using 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/prefixaddresses, netmasks or prefixes, IPv4 and/or IPv6 gatewaygateways, DNS servers, DNS domain names, NTP serverservers, time zonezones, server namenames, and database name.
Refer to the names. For more details, refer to Configuring Server Options for more details.
The NetMRI image is initially released with one pre-installed preinstalled network interface, but additional interfaces can be added for scanning purposes or HA. If a server has two connected network adapters, the first 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 automatically, you should assign the IP address as MGMT and configure it statically.
...
The SCAN interfaces will not receive an IP address during the initial setup, because the DHCP client is enabled only enabled for the MGMT interface. In such casesFor the SCAN interfaces, you will need to manually determine check the IP address assigned by the DHCP server. For AWS or and OpenStack, you can check this the IP address in the instance instance’s description, the network section, or ENI the ENI’s description. Please note that at this time, NetMRI currently does not support DHCP clients for the SCAN interfaceinterfaces.

If you are configuring server options, verify the following:
IPv4 Address
: a public or private* IPv4 address
*
IP addresses
from the 169.254.1.0/24 subnet are not permitted.
IPv4 Network mask
: an IPv4 subnet
mask
IPv4 Gateway
: a public or private IPv4 address from the same subnet as that of the IPv4
address
IPv6 Address
: a public or private IPv6 address
IPv6 Prefix
: the IPv6
prefix’s length
IPv6 Gateway
: both a public IPv6 address and a private IPv6 address from the same subnet
DNS Server
: an IPv4 or IPv6 address
DNS Domain Name
: up to 253 symbols (including the server’s name), case-sensitive alphabetic
characters, numbers, hyphens (-), and dots (.);
a label cannot begin or end with a hyphen
Server Name
: up to 63 symbols, including case-insensitive alphabet
characters, numbers, and hyphens (-)
NTP Server
: an IPv4 or IPv6 address or a domain name
Time Zone
: any of the
time zones listed in
version 2023c of the IANA database ; however, NetMRI can use only a few specific regions, such as Africa, America, Antarctica, Asia, Atlantic, Australia, Canada, Europe, India, Pacific, US
Database Name: case-insensitive alphabetic characters, digits, dots, hyphens, underscores, and spaces
; 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, then an IPv4 netmask, IPv6 prefix, IPv4 gateway, and IPv6 gateway are necessary.
...
The DNS settings set up for the MGMT interface will be applied globally. An interface DNS servers for each interface will respond to server is used for DNS queries only when if the domain name in the query matches the domain name configured set up for that specific this interface; otherwiseif they do not match, the global DNS servers will be used.
...
Upon the initial launch, NetMRI will attempt to acquire an the IP address for of the MGMT interface from the DHCP server if it is accessible within the network. If the DHCP server is not availableaccessible, you can use the default IP address 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 that of 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 connect in this manner might cause the SSH connection to drop while new settings are applied, potentially causing and this might cause some settings to be missed.
