DMA Operations Guide Embedded DNS
260 Polycom, Inc.
You can enable these embedded DNS servers on the Embedded DNS page.
This is a supercluster-wide setting.
If you wish to use this feature, your enterprise DNS must place the Polycom
DMA system supercluster in charge of resolving a sub-domain. To do this, you
must:
• Add NS records to your enterprise DNS so that it refers requests to resolve
the site-based logical host name to these embedded DNS servers.
• Configure your enterprise DNS to forward requests for names in the
site-based logical host name to any of the clusters in the supercluster.
See “Additional DNS Records for the Optional Embedded DNS Feature” on
page 24.
The following table describes the fields on the Embedded DNS page.
To enable DNS publishing
1 Be sure you’ve added the required NS records, one for each cluster in the
supercluster, to your enterprise DNS and have configured it to forward
requests for names in the logical Call Server domain to any of the clusters
in the supercluster (see “Additional DNS Records for the Optional
Embedded DNS Feature” on page 24).
2 Go to Admin > Call Server > Embedded DNS.
3 Click Enable embedded DNS service.
4 Enter the domain name of the enterprise domain for which the DMA
system is to provide DNS and click Update.
5 Reconfigure your endpoints to register to the correct domain name for
their site.
The correct domain name is:
callserver-<site name>.<logical Call Server domain name>
