Add Required DNS Records for the Polycom DMA System

Note

If you’re not familiar with DNS administration, the creation of various kinds of DNS resource records (A/AAAA,NAPTR, NS, and SRV), your enterprise’s DNS implementation, and tuning for load balancing (if needed), please consult with someone who is.

In order to access your Polycom DMA system by its host name instead of by IP address, you (or your DNS administrator) must first create an A (address) resource record (RR) for IPv4 and/or AAAA record for IPv6 on your DNS server(s).

For a two-server cluster configuration, at a minimum, create a record for the virtual host name and IP address. This address is shared between the servers in a two-server cluster configuration. For administrative convenience, we recommend that you also create alias records for the physical host name(s) and IP address(es). For a superclustered system, A/AAAA records for each physical host name, physical IP address, virtual host name, and virtual IP address are mandatory.

Note

Depending on local DNS configuration, the host name could be the Polycom DMA system’s fully qualified domain name (FQDN) or a shorter name that DNS can resolve. For some features, such as Microsoft Exchange Server integration, it’s imperative that the virtual host’s FQDN can be resolved in DNS, especially by the Exchange server.

If you’re using split network interfaces, we recommend creating alias records for both the management and signaling host names and addresses.

The DNS server(s) should also have entries for your Microsoft® Active Directory® server (if different from the DNS server) and any external gatekeepers or SIP peers.

You may need to create additional DNS records as described below.
