Add an X7.0.n VCS to a VCS X7.0.n cluster
(n is
the same value on all peers)
Follow this process if you have an existing X7.0.n cluster (of one or more peers) to which you want to
add another Cisco VCS peer. If you do not have an existing cluster, following the instructions in the
section “Create a new cluster of VCS X7.0.n peers”.
add another Cisco VCS peer. If you do not have an existing cluster, following the instructions in the
section “Create a new cluster of VCS X7.0.n peers”.
Note: You can have up to 6 Cisco VCSs, including the master Cisco VCS, in a cluster.
This process will add an X7.0.n VCS to the cluster and replicate the cluster Master’s configuration
onto the Cisco VCS.
onto the Cisco VCS.
Note:
Cisco VCS clusters peers must all run the same version of code as the master, for example all
X7.0.n (x is the same value on all peers).
X7.0.n (x is the same value on all peers).
Only one Cisco VCS must be added to the cluster at a time.
On the Master Cisco VCS:
1. Ensure that the Master Cisco VCS does not list this new Cisco VCS peer in any of its neighbor
zones or traversal zones (VCS configuration > Zones then check each neighbor and traversal
zone).

Note: The Master VCS will be the source of the configuration for this new VCS peer and all other
VCS peers in the cluster. When a VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
VCS peers in the cluster. When a VCS is added to the cluster, its configuration will be deleted and
replaced by that from the Master.
On the Cisco VCS to be added to the cluster:
1. Check that no other VCS (anywhere) has this VCS’s IP address in their Alternates or Clustering
Peers list.
2. Check that the VCS software version is identical to the version running on the Master and any
other cluster peers of the existing cluster (X7.0.n - x is the same value on all peers).
3. Backup the VCS (See Appendix 1 for details).
On the web interface of the Cisco VCS being added:
4. Review the configuration to ensure that the Cisco VCS has:
•
A valid Ethernet speed (System > Ethernet).
•
Valid IP address and IP gateway (System > IP).
•
The same set of Option keys as those installed on Master peer (Maintenance > Option
Keys).

Note: The number of traversal and non-traversal call license keys may be different on different
peers; all other license keys must be identical on each peer.
