Morning folks. We need to “re-ip” our UMS server as we need to move it to a new subnet. Do the TC’s use a DNS name to find UMS, or do they use an IP? After the IP address change, how will the clients find the UMS that manages them
To register IGEL devices automatically they have to get an information where to find the management server. There are two possibilities:
• DNS entry `igelrmserver` (The _Type must be: Record Type A_)
• DHCP option (224)
The devices are already registered with UMS, this is not a new rollout.
if igel os devices get an ip address via dhcp from a zone where the 224 option is set they contact that ums server, if there is not a dhcp option 224 set, but a dns type a record exists (via configured dns) than they look for an ums server there.
if the via dhcp/dns configured ums has the same certificate as the old one (or the same one with new ip), than the devices connect to that ums server.
if it is a new server: if you have imported the devices from the old ums server or you configured the new ums server to auto-register new devices than the devices will connect to the new ums server.
Got it. Thank you for the explanation.
