Strange problem with CUCM 11.5 replication

There were several reboots of Primary and Secondary SUBS. I noticed that Primary SUBS couldn’t authenticate on PUB. I tried to restore system from backup, but I cannot restore Primary SUBS.

Primary SUBS now serves ~3500 phones.

Finally, I have strange situation:

admin:utils dbreplication runtimestate

 

Server Time: Wed Apr  7 18:49:32 +03 2021

 

Cluster Replication State: BROADCAST SYNC ended at: 2021-04-07-17-57

     Sync Result: SYNC COMPLETED on 706 tables out of 706

     Sync Status: All Tables are in sync

     Use CLI to see detail: 'file view activelog cm/trace/dbl/20210407_175345_dbl_repl_output_Broadcast.log'

 

DB Version: ccm11_5_1_13901_3

 

Repltimeout set to: 300s

PROCESS option set to: 1

svrua102-103-group it’s a name of Cisco Unified Communications Manager Group and it has correct Primary and Secondary SUBS. Moreover, everything is right in PUB Web Administration.

There should be SVRUA000102 (Primary SUBS)

By the look of this I would recommend you to reach out to TAC to get help with this.

Can you share the Server configuration from CUCM administration page. Need to see the servers configured. 

 

Subscriber cups DBSub not authenticated - INITIATOR since Wed Apr 7 15:03:23 2021 >>> Your CUPS server is not authenticated, is this server UP and RUNNING ? is there a firewall between this server and CUCM ?

Hello Nithin,

 

I have uploaded some interesting screens from PUB.

Our primary goal is to connect Primary SUBS with PUB and get fully managed system. I'll try to check CUPS later.

There are no firewall between components.

 

Best regards,

Sergey

As @roger mentioned, Open a TAC case.
