I have a CUCM 8.6.2a running on a UCS 220 for some reason the ip address went blanc at some point after install, when I reset it it took restarted then I couldn't get back into cli.
Nothing worked, Has anyone seen this,.
It is easy to delete and recreate however seems weird,,
You have ot set IP to install so I am not sure why it ended up empty.
It was 8.6.2-2000
