Managing clusters and peers

Setting up a cluster

Before creating your cluster, ensure that all the VCSs to be added to the cluster:
are using TMS version 12.6 or later as their external manager
n
have the same software version and
n
call licenses and TURN relay licenses which may be different on each peer)
each have a different system name
n
each have a different LAN
n
enabled)
have H.323 enabled (even if all endpoints in the cluster are SIP only, H.323 signaling is used for endpoint
n
location searching and sharing bandwidth usage information with other peers in the cluster)
Then, to create your cluster you must first configure a master peer and then add the other peers into the
cluster one-by-one.
You are recommended to backup your VCS data before setting up a cluster.

Cluster name
The Cluster name is used to identify one cluster of VCSs from another. Set it to the fully qualified domain
name used in SRV records that address this VCS cluster, for example cluster1.example.com.
If you are using FindMe and you change the Cluster name, you may need to reconfigure the user accounts.
See the Clustering and FindMe
Cluster pre-shared key
The VCS uses IPsec (Internet Protocol Security) to enable secure communication between each cluster
peer.
The Cluster pre-shared key is the common IPsec access key used by each peer to access every other peer
in the cluster.
Each peer in the cluster must be configured with the same Cluster pre-shared key.
