[Issue in StarlingX 4.0] Deploying STX on a VLAN Based Network

[Lokendra]

Brief Description
-----------------
We are deploying StarlingX 4.0 in Dedicated Storage Model and we need to have our management network as VLAN-tagged for deployment reasons.

As per the link below, in that case we must configure the optional untagged PXE boot network for PXE booting of new hosts using IPv4.

Can someone please elaborate steps to do so. as we are facing issue in PXE booting of Controller-1

https://docs.starlingx.io/planning/kubernetes/network-planning-the-pxe-boot-network.html

Steps to Reproduce
------------------

follow this
https://docs.starlingx.io/deploy_install_guides/r4_release/bare_metal/dedicated_storage_install_kubernetes.html

and modify the host details as per below:

system host-if-add controller-0 -V 410 -c platform eno2.mgmt vlan eno2
system host-if-add controller-0 -V 413 -c platform eno2.pxeboot vlan eno2

system host-if-add controller-0 -V 411 -c platform eno2.cluster vlan eno2
system host-if-add controller-0 -V 412 -c platform eno2.ironic vlan eno2

OAM_IF=eno1
MGMT_IF=eno2.mgmt
CLUSTER_IF=eno2.cluster
PXE_IF=eno2.pxeboot
system host-if-modify controller-0 lo -c none
IFNET_UUIDS=$(system interface-network-list controller-0 | awk '{if ($6=="lo") print $4;}')
for UUID in $IFNET_UUIDS; do
    system interface-network-remove ${UUID}
done
system host-if-modify controller-0 $OAM_IF -c platform
system interface-network-assign controller-0 $OAM_IF oam

system host-if-modify controller-0 $MGMT_IF -c platform
system interface-network-assign controller-0 $MGMT_IF mgmt

system host-if-modify controller-0 $CLUSTER_IF -c platform
system interface-network-assign controller-0 $CLUSTER_IF cluster-host

system host-if-modify controller-0 $PXE_IF -c platform
system interface-network-assign controller-0 $PXE_IF pxeboot

Observation:
 even after enabling the VLAN related config in BIOS setting of controller-1 and then trying to bring up controller-1, we are not even getting the entry in system host-list.

Expected Behavior
------------------

Controller-1 should come up successfully for further configuration.

screening: missed this LP earlier. Using vlans for the mgmt network works and is a common config. There aren't logs or enough info here to determine what is wrong in this particular setup. This is likely some specific configuration issue with this setup.

Marking as Incomplete as more info is needed.
