The requirements in the previous table outline the minimum hardware configuration
needed to operate Cisco Unified Operations Manager at different scalability levels. The
client requirements dictate the platform from which the user interfaces (Internet browser-
based) are invoked.

3.3
Preparing the Network
3.3.1 Register Devices and Interfaces in DNS
For the name lookup process to work, devices should be registered in DNS. When the
discovery process encounters a device, it performs a reverse lookup on the IP address
where the device was encountered to get the hostname for the device. Operations
Manager then performs a forward lookup on the hostname to get the preferred
management interface for the device. Hence, all interfaces should be registered in reverse
DNS, but only the preferred management interface should be registered in the forward
lookup. The loopback interface is an ideal candidate, because it is never down. Ensure
that the other interfaces do not have forward lookup pointing to incorrect DNS names.
