Users Guide

As part of automation, OMNI does the following automation tasks:
● Creates host and edge overlay networks. OMNI notifies the creation of host and edge overlay NSX-T networks using UI
alerts. You must configure the L3 properties of the overlay networks manually.
NOTE: In NSX-T deployment, when you add a host to a new rack, you must update the L3 properties of the host
overlay network for the new rack manually.
● Creates edge uplink networks with IP address configured.
● Tags the above networks that are created to the corresponding server interface profiles and synchronizes NSX-T networks.
● Creates the route policies for NSX-T Tier-0 interfaces with a name of the Tier-0 interface and associates the policies with
the switches on the edge rack.
NOTE:
If you want to manually configure the SmartFabric for NSX-T deployment, you must not add the NSX-T instance in
OMNI.
OMNI behavior
● OMNI creates all NSX-T networks as multirack L3 VLAN networks.
● If OMNI NSX-T automation service is running while NSX-T configuration is in progress, OMNI might display error alerts while
the NSX-T is partially configured. You can check and acknowledge the alert messages once the configuration is complete
and OMNI automation is successful.
● If you have added an NSX-T instance in OMNI with a preconfigured SmartFabric with BGP policies or networks, OMNI
notifies the relevant errors if there is a mismatch between the SmartFabric network configuration and NSX-T. If there is no
mismatch, OMNI uses the existing configuration.
The following table lists the OMNI alert message for the configurations that are done manually:

configuration
Behavior Alert message Recommendation
Configure the
rack settings of
the edge rack
for each uplink
network with an
IP address and
prefix.
If OMNI identifies an existing
uplink network with the same IP
address and prefix, it uses the
existing network and does not
create a network.
— —
If the uplink network already has
the edge rack configured with a
different IP address and prefix,
OMNI notifies the information as
alerts.
Rack {rack_id} already
configured for
{network_id}
You can manually edit the
configuration with the alert
message information or delete
existing network so that OMNI
automation can create it.
If the uplink network already has
a rack with the IP and prefix
combination that OMNI wants to
use to configure the edge rack, it
notifies the information.
'\'{ip}\' already exists
on Rack {rack_id} for
{network_id}
