and service policies. Cisco BAC relies upon the CNR DHCP server for IP address assignment, DNS, device
detection, and load distribution among Cisco DPE servers.

Platform Support and System Requirements
The Cisco BAC RDU, DPE, KDC, and CNR components are supported on the Sun Solaris 10 operating systems
based on SPARC architecture.
Starting with Cisco BAC 4.1, Cisco BAC provisioning group components - BAC DPE, CNR DHCP, and CNR DNS are
also supported on Red Hat Enterprise Linux 5 and above. These systems have been tested on Cisco Unified
Computing System (UCS).
