CUCM/CUC 9.1 – Fun with Certificates!

pitviper

I figured I’d pass this along since many will be upgrading their labs in the upcoming year. So I’m working on a complete refresh to UC software 9.1 and things have been a bit flaky of late to say the least = lots of oddities, things like login errors, replication errors, unable to manage services on the SUB, servers disconnecting from the license manager, and so on – on all CUCM severs as well as CUC. Mind you this is a 100% fresh install. I regenerated all self signed certs (tomcat, ipsec, CallManager, CAPF, and TVS) from OS Administration on all servers and rebooted every server in the cluster, and all is well again.

Is this for your lab or an actual production environment?
