Verdepollo,

Thanks for the reply. Just before the holidays, these are the steps I used to create the vnic:

1) create /etc/hostname.<interfacename>:<n> containing the hostname of the virtual IP
example:

/etc/hostname.bge0:1

2) add the hostname and virtual IP to /etc/hosts

3) use the following commands to configure the interface:
ifconfig <interfacename>:<n> plumb

example:
ifconfig bge0:1 plumb

ifconfig <interfacename>:<n> <IP address> netmask <netmask> broadcast + up

example:
ifconfig bge0:1 10.67.1.141 netmask 255.255.255.0 broadcast + up

2) To make the virtual interface persist following a reboot, you can add the ip address or hostame in the file /etc/hostname.hme0:1

It seems to have worked, but I need to make sure that network devices configured to send to the plumbed IP, are actually getting recieved by the NNMi application.

systemd-networkd.service

SYSTEMD-NETWORKD.SERVICE(8)				     systemd-networkd.service				       SYSTEMD-NETWORKD.SERVICE(8)

NAME

       systemd-networkd.service, systemd-networkd - Network manager

SYNOPSIS

       systemd-networkd.service

       /lib/systemd/systemd-networkd

DESCRIPTION

       systemd-networkd is a system service that manages networks. It detects and configures network devices as they appear, as well as creating
       virtual network devices.

       To configure low-level link settings independently of networks, see systemd.link(5).

       systemd-networkd will create network devices based on the configuration in systemd.netdev(5) files, respecting the [Match] sections in
       those files.

       systemd-networkd will manage network addresses and routes for any link for which it finds a .network file with an appropriate [Match]
       section, see systemd.network(5). For those links, it will flush existing network addresses and routes when bringing up the device. Any
       links not matched by one of the .network files will be ignored. It is also possible to explicitly tell systemd-networkd to ignore a link by
       using Unmanaged=yes option, see systemd.network(5).

       When systemd-networkd exits, it generally leaves existing network devices and configuration intact. This makes it possible to transition
       from the initrams and to restart the service without breaking connectivity. This also means that when configuration is updated and
       systemd-networkd is restarted, netdev interfaces for which configuration was removed will not be dropped, and may need to be cleaned up
       manually.

CONFIGURATION FILES

       The configuration files are read from the files located in the system network directory /lib/systemd/network, the volatile runtime network
       directory /run/systemd/network and the local administration network directory /etc/systemd/network.

       Networks are configured in .network files, see systemd.network(5), and virtual network devices are configured in .netdev files, see
       systemd.netdev(5).
