Hello,
On my environment lab I'm currently trying to install a node (CN) by using vlan
tagging on the management network.
I'm running xCAT release 2.16.2 on top of RHEL 7.9.
Note: I also tried to did the install without the vlan tagging and of course
it's working well without pb on the iPXE side as I still have the same setup on
the node except for the vlan interface.
On my server a tagged vlan is defined, on the compute I enable the vlan with an
id (same as server) at the BIOS level in order to be able to communicate with
the server.
On the switch I also create a vlan with ports (tagged) connected to both
servers (MN & CN).
Here are some setup on site table:
[root@mosupc ~]# tabdump site | grep -E "dns|dhcp"
"dnshandler","ddns",,
"dhcplease","43200",,
"dhcpinterfaces","eno1.21,eno1",,

My Configuration is as below:
* Management server => DL385 Gen10
* Compute Node => Apollo 4200 Gen10
* 1 Procurve switch (2848) for the management network
* Another Procurve for the BMC/iLO network
I faced an issue during the IPXE boot just after the DHCP sequence and the
download of the NBP file (xnba.efi in my case), then the network is no more
working
The network error I have on the console is:

Question: Is vlan tagging is supported on the management network on xCAT setup?
After googling without success around iPXE, I would like to have any hints on
where to look for in order to progress on this topic.
Thanks in advance for any ideas which could help on that.
If additional logs are needed I'll provide them.
