SOPORTE,
I think this is what is happening:
During xcatprobe a temporary node definition xcatmntest with ip=serverip
and mac=aa:aa:aa:aa:aa:aa is created.
Then "makedhcp xcatmntest" command is ran to update the DHCP configuration
file. After that, "makedhcp -q xcatmntest" command is ran to
query the xcatmntest node and verify the same ip and mac are
returned.
For some reason on your system "makedhcp -q xcatmntest" does not return
anything and generic "DHCP server reply is wrong" message is
returned.
You can run "makedhcp -q" against some of your real nodes and verify
correct IP and MAC are retuned for them. If so, you can ignore
this xcatprobe failure.

Ok, the "-V" flag did not do what I expected.
Edit file /opt/xcat/probe/subcmds/xcatmn and around line 19, flip "my
$verbose = 0;" from 0 to 1. Then rerun "xcatprobe xcatmn -i eno5"
without the "-V" flag.

SOPORTE,
Is this problem related to "xCAT 2.16.2 new xNBA issue" thread.
If not, can you start a new thread ?
Try to rerun the xcatprobe with verbose flag:
xcatprobe -V xcatmn -i eno5
