Create a Segment (On-Prem)

You can create a segment on an on-prem NSX server system by using the Invoke-PatchInfraSegment cmdlet.

To create an on-prem (flexible) segment, you must specify a transport zone and assign a subnet.

Prerequisites

• Verify that you are connected to an on-prem NSX server system.

• Verify that your system has Tier-1 gateway(s).

Procedure

1. Retrieve transport zone details.

   $tzs = Invoke-ListTransportZonesForEnforcementPoint -EnforcementpointId default -SiteId default
   $tz = $tzs.Results | where {$_.DisplayName -eq $TransportZone}

2. Prepare the input for the segment subnet.

   $segmentSubnet = Initialize-SegmentSubnet -GatewayAddress $GatewayCIDR

3. Retrieve the Tier-1 paths.

   $t1s = Invoke-ListTier1
   $t1 = $t1s.Results | where {$_.DisplayName -eq $T1GatewayName}

4. Prepare the input for the segment.

   $segment = Initialize-Segment -DisplayName $SegmentName -TransportZonePath $tz.Path `
              -Subnets $segmentSubnet -ConnectivityPath $t1.Path

5. Invoke the operation.

   Invoke-PatchInfraSegment -Segment $segment -SegmentId $SegmentName
