Universal Cds Override With A Dns Entry; Broadcast Discovery - Black Box Coalesce WC-COA Deployment Manual

2.8.3 Universal CDS Override with a DNS Entry

With CDS installed, configuring DNS will enable users to view and select displays available for connection without entering the
CDS IP address on their client device. Furthermore, any client, including clients downloaded from the app store for mobile devices,
will see Coalesce enabled displays as soon as they join the network. This can override the CDS IP address if one has been entered
previously on the client device, so guest users who may also be using Coalesce on their home network, will still see your Coalesce
displays, even if they have configured CDS on their device for a different network in the past.
Recommended for:
Networks with switches and/or multiple subnets. Coalesce collaborators with different network access. Users are not required to
enter an IP address to connect.
How to Setup:
Add a DNS entry to resolve the CDS IP address to its URL. Use one of the two methods below. Please refer to the CDS Reference
Guide from the http://www.blackbox.com for more details about the DNS entry options.
• Method 1. Create a "Coalesce_customer_internal" domain zone and add an "A" record that maps the name
'Coalescedirectoryservice.Coalesce_customer_internal" to the IP address of the machine where the CDS is installed.
• Method 2. Coalescedirectoryservice is an unqualified host name because it does not include a domain name such as
"blackbox.com" "university.edu." By leaving off the domain name, we allow the client operating system the option of
appending the local domain name. This allows the IT department to add an CDS record to their name (e.g. university.edu).
This method requires your internal DHCP servers to append the appropriate suffix.

2.8.4 Broadcast Discovery

Coalesce can use UDP broadcast packets to automatically populate client devices with a list of Coalesce displays on the network
to connect to. Broadcast discovery is enabled by default when the Coalesce is deployed off-network in WAP mode.
Recommended for:
Dedicated network configurations and small single network configurations that do not use a switch. Users will not be required to
enter an IP address to connect.
How to Setup:
1. Access the configuration panel for your Coalesce units by browsing to the Coalesce units IP address(es) and selecting "config-
ure." The configuration panel settings can also be accessed from Coalesce display interface by clicking the Coalesce icon in the
bottom right corner.
2. On the Display tab under the Naming and Discovery heading, enable the option to "Broadcast display name on the network."
