VCS Cluster

[vikas.kumar11@wipro.com]

Dear Team,

I need you support for VCS- C clustering.

This is first time we are doing this. We have uploaded the same set of license in both the VCS-C and done the peering configuration in VCS-C which is working.

What will be next step and DNS configuration we need to do for clustering and what setting we need to apply in End point for gatekeeper.

Based on Cisco VCS Cluster Creation and Maintenance Deployment Guide: 

The DNS servers used by the VCS peers must support both forward and reverse DNS lookups of Cisco TMS and all VCS peer addresses; the DNS servers must also provide address lookup for any other DNS functionality required, such as:

— NTP servers or the external manager if they configured using DNS names

— Microsoft Lync Server FQDN lookup

— LDAP server forward and reverse lookup (reverse lookups are frequently provided through PTR records) Note: DNS server configuration does not replicate and you must configure the DNS server address on each peer.

■ A DNS SRV record is available for the cluster which contains A or AAAA records for each peer of the cluster. This configuration is advised for video interoperability and business to business (B2B) video calling, but is not required for Mobile and Remote Access.

■ (For MRA) Create a collab-edge SRV record for each peer in the VCS Expressway cluster

■ (For B2B only) The VCS Expressway cluster has a DNS SRV record that defines all cluster peers

For endpoints settings for gatekeeper registration refer to p. 44-45.

In addition to what Acevirgil mentioned, you'll also want to be sure you following the VCS Basic Configuration (Control with Expressway) Deployment Guide (X8.7) in order for your endpoints to be able to register and make calls etc, if you haven't done so already.

Dear Team,

As we understand that we need to create the cluster FQDN that needs to be set up in Endpoint.

Just want to understand Cluster FQDN will point to which IP ( VCSC1 or VCSC2 ).

Does it require only A record or SRV records also for VCSC1 and VCSC2.

We don't have any Expressway cluster in solution only VCS-C cluster.

The cluster FQDN should point to both A records of each VCS peer, and the SRV records for our SIP domain point to the cluster FQDN.  Another option is instead of pointing to the SRV records to the single cluster FQDN which in turn sends it to either VCS peer, you could have your SRV records point to each VCS peer directly.
