Cluster ID parameter is an unique identifier for the clusters. By default the value for Cluster ID is set to “StandAloneCluster”. When configuring Extension Mobility Cross Cluster (EMCC) or Intercluster Lookup Service (ILS), cluster id has to be unique across all the cluster. Adding to this Cluster ID parameter is also used in Call Detail Record (CDR) field.

To change Cluster ID, it is recommended to do the changes in a maintenance window.  Below are the steps to change the cluster id:
 

Change Cluster ID in CUCM:

  • Login to Cisco Unified Communications Manager Administration
  • Navigate to System > Enterprise Parameters
  • Change Cluster ID from StandAloneCluster to your desired clusterid
  • Click Save

Restart Services in CUCM:

  • Login to Cisco Unified Communications Manager Serviceability
  • Navigate to Tools > Control Center – Feature Services > Restart Cisco CallManager Service
  • Navigate to Tools > Control Center – Network Services > Restart Cisco AMC Service

Validate Changes:

Now to make sure that the changes has taken place – follow the steps below:

  • Make couple of calls from Phone A to Phone B
  • Download CDR Report from Cisco Unified Communications Manager
  • Open the CDR Report and locate the call made from Phone A to Phone B
  • Search for column “globalCallId_ClusterID” and you should be able to see the new Cluster ID you have configured

Hope this helps!

    1. Do we need to restart Cisco CallManager Service only on PUB or SUB as well.
    2. Do we need to make the clsuter id changes on SUB as well or making changes on PUB will be suffice.

    Regards
