If DNS is
configured on a device, ensure that Cisco Prime Collaboration can resolve the
DNS name for that device. Check the DNS Server configuration to make sure it is
correct. This is critical for Cisco Unified CM, Unified Presence Server, Unity
Connection devices. Cisco Prime Collaboration needs to resolve the hostnames
for MGCP gateways. This is because, the MGCP gateway hostnames are not added to
the DNS server generally as the gateways and Cisco Unified CM are capable of
operating together without DNS resolution. However, the Cisco Unified CM does
not resolve the hostnames for MGCP gateways, considering it as an FQDN.

Clients. These endpoints are discovered only with the discovery of the
call processor with which they are registered.
ensure that the device credentials that you have entered are correct. During
the discovery process, based on the device that you want to discover, Cisco
Prime Collaboration connects to the device using CLI, HTTP/HTTPS, or SNMP.
When you add devices, the

discovering devices, if the IP address changes for network devices and
infrastructure devices (such as CTS-Manager, CTMS, Cisco Unified CM, Cisco MCU,
Cisco VCS, Cisco TS, and so on), you must rediscover these devices by providing
the new IP address or hostname. See
for information on rediscovering devices.
If a managed device is
removed from the network, it will continue to be in the Managed state until the
next inventory collection occurs, even though the device is unreachable. If a
device is unreachable, an Unreachable event for this device appears.
Configuration changes on a
device are discovered by Cisco Prime Collaboration only during the inventory
collection process. Therefore, any changes to a device’s configuration will not
be shown by Cisco Prime Collaboration until the next inventory collection after
the configuration change.
To periodically update
inventory, and synchronize the inventory with the Cisco Prime Collaboration
database, you must perform inventory update. For more information, see
and Collect Inventory Details.
