Issue/Introduction
The environment is running NSX with VLAN Segments configured
After VLAN segment creation, and connecting VM's to these segments through VC, you see network showing as "inaccessible"
Environment
VMware NSX
Cause
This can happen for the reasons below:
VLAN TZ is not applied to this Segment and only an Overlay TZ is applied
The hosts in the cluster within NSX are not all showing as being applied to this TZ.
Resolution
Verify that VLAN TZ is applied to this VLAN segment
Confirm which Hosts the TZ is applying to within the cluster under Networking>Transport Zones
Apply a Transport Node Profile to the Host cluster
Create a TNP under
System
>
Fabric
>
Hosts
>
Transport Node Profile
>
Add Transport Node Profile
.
Input all required details for VDS, VC, and TZ's making sure to add the Overlay and VLAN TZ's to this TNP
Select Radio to select the entire cluster under System>Fabric>Hosts that you want to apply this TNP to
Click Configure NSX and select the newly created TNP
Confirm the TZ is being applied to all hosts now under Networking>Transport Zones
Connect VM's in VC to this VLAN Segment and you shouldn't see the "inaccessible" error anymore.
