The network override options are no longer present in the vSphere Namespace creation page in 8.0U3 and 8.0U3a

Issue/Introduction

Prior to the 8.0 Update 3 release, a vSphere administrator could provide custom network configuration instead of the default network configuration used when a vSphere Namespace is created. In the 8.0 Update 3 release, the UI option to override the network configuration is not available. 

This is what is expected when creating a new supervisor namespace: 

However with this issue the Override Supervisor Network Settings button does not appear in the UI.

Environment

Issue only occurs on 8.0U3 and 8.0U3a

Release name	Version	Release Date	VAMI / Release Notes	Client / MOB / vpxd.log
vCenter Server 8.0 Update 3a	8.0.3.00100	2024-07-18	24091160	24091160
vCenter Server 8.0 Update 3	8.0.3.00000	2024-06-25	24022515	24022515

Resolution

Issue will be resolved in the next release of vCenter. 

To workaround the issue, the Supervisor Namespace Creation can still be done via the dcli.

The last command is what creates the namespace with the override on the T0 Gateway. 

Note: For arguments that require JSON input, you can format them as follows:

--namespace-network-network-egress-cidrs '[{"address": "x.x.x.x", "prefix": 25}]'
