This chapter provides information on the Cisco Server Suite 1000 enhanced TCP/IP server applications. The information is organized into the following sections:
The Cisco Server Suite 1000 is a suite of enhanced TCP/IP server applications that are easily managed and configured with a graphical user interface (GUI). These servers, DNS, DHCP, BOOTP, TFTP, NTP, and syslog, are the most common TCP/IP servers used in building and maintaining TCP/IP networks. With the Cisco Server Suite 1000, administrators can now get a consistent level of network services across both UNIX and Windows NT with an easy-to-use GUI.
The Cisco Server Suite 1000 is designed for the following applications:
- DHCP in a switched network
- The Cisco DHCP server allows organizations to use DHCP in a large switched network. The depletion of IP addresses on the Internet has forced organizations to use classless inter domain routing (CIDR) blocks or groups of Class C networks to build physical networks with more than 256 nodes. This has created a problem for network administrators who want to use DHCP on a large switched network with more than 256 nodes.
- Organizations building large switched networks with TCP/IP assign multiple logical IP networks on a single physical switched network. At the same time, organizations want to take advantage of DHCP to dynamically configure a large number of PCs on their network. The Cisco DHCP server supports address pools that contain multiple logical networks on the same physical network.
- The Cisco DHCP server dynamically updates DNS with the domain name and the IP address allocated to the DHCP client. This requires the Cisco DNS/DHCP Manager.
- The Cisco DHCP server can combine pools of an IP address from multiple networks into a single large pool of addresses.
- TCP/IP servers for Windows NT
- Although Microsoft includes a TCP/IP stack with the Windows NT operating system, many critical TCP/IP services are missing from Windows NT. The Cisco Server Suite 1000 enhances Windows NT by providing services or replacing Windows NT existing services with enhanced services. These services include a DHCP server that also supports BOOTP, a DNS server for domain name service, a TFTP server for booting network devices, an NTP server for synchronizing time on a network, and a syslog server for remotely logging errors from a network device.
- The Cisco DNS/DHCP Manager ships additional network services used to efficiently maintain a TCP/IP network. A DNS server provides name service, NTP provides times synchronization, TFTP loads binary images and configuration files to network devices (including routers), and a syslog server logs error messages from network devices over the network. All of these services can be configured with an easy-to-use GUI.
- Configuring and managing Cisco internetwork hardware
- The Cisco Server Suite 1000 provides networking services on UNIX platforms and Windows NT for network managers building networks based on Cisco internetworking hardware. Network managers building networks based on Cisco internetworking hardware need support for networking services such as BOOTP, TFTP, NTP, and syslog.
- BOOTP provides the initial configuration information such as the IP address, default router, and TFTP server. An NTP server provides time synchronization. TFTP servers load binary images, including Cisco IOS software and configuration files to network devices including Cisco routers and switches. A syslog server is used for logging error messages from network devices over the network. All of these services are easily configured with a GUI.
