Because the IP Manager is a component of many deployments, the IP Availability Manager has been selected as the central repository for storing the device access credentials for other Domain Managers — such as command line interface (CLI) login credentials required by Network Protocol Manager for EIGRP and Network Protocol Manager for IS-IS to perform CLI discovery and, optionally, CLI polling. The satellite Domain Managers import the device access credentials as well as initial topology from IP Availability Manager when they add IP Availability Manager as a source.
