after the upgrade of my CUCM from 11.5 to 12.5, the built-in DHCP service on the CUCM stopped working.
The IP Phones are not able to acquire ip anymore.
Checking the logs on RTMT, i see this after i restart DHCP Monitor Service:
: 0: cucm-pub.confag.locale.confag.locale: Feb 23 2019 08:16:50.181 UTC : %UC_JAVAAPPLICATIONS-3-CiscoDhcpdFailure: %[Reason=dhcpd is stopped][ClusterID=][NodeID=cucm-pub.confag.locale]: DHCP Daemon stop running.
Can someone help me with this issue? Before the upgrade all was working fine
Wow, someone actually uses the co-resident dhcpd! The overwhelming consensus is not to do that; even the SRND recommends against it.
If you have less than a 1000 devices in the cluster, your best bet here is probably a TAC case to find what is likely a new defect. If I were you, I would just move DHCP to your normal (hopefully redundant) DHCP server; or, run it on a router instead.
Did you ever find a solution for this? I'm having the same problem on 126.96.36.19900-146. I have opened a TAC case however but was wondering if you found a solution.
Thanks and have a nice day.
