PC Magazine Dec 7, 1993 v12 n21 p335(21) SNMP: Living Up to Its Name? by Michael Blakeley Network management can be a costly and time-consuming endeavor that can impact your success as a network administrator. So why add to the complexity by considering the Simple Network Management Protocol (SNMP)? SNMP was designed for the Internet, a vast expanse of computers linked across the globe via TCP/IP. Early on, the Internet consisted mainly of educational and government institutions. But SNMP soon became the sine qua non of corporate networks as well. With its ability to pull data regarding hubs, client systems, and routers across increasingly heterogeneous networks, SNMP found its way onto the desktops of many corporate WAN managers. In the second quarter of this year, standards for Version 2 of SNMP were released. SNMP 2 adds manager-to-manager communications, security features (including user authentication and DES encryption), and bulk data retrieval, but it maintains backward compatibility with older SNMP agents. Transport mappings are now specified for AppleTalk, IPX/SPX, OSI, and TCP/IP, allowing PCs to be managed without a TCP/IP stack. SNMP 2 is also closely tied to the efforts of the Desktop Management Task Force, which has developed a reference model for network management called the Desktop Management Interface (DMI). SNMP management applications can be written for Windows and are now capable of talking to both TCP/IP and IPX agents. NetWare servers can thus be managed remotely without the user having to install TCP/IP. PCs with SNMP-aware network-interface cards can be managed over IPX, whereas existing TCP/IP agents in hubs and routers can continue to be managed with the same applications. One example of network management's new course is LANDesk/OpenView for Windows, a joint venture of Hewlett-Packard Co. and Intel Corp. that will support NetWare, SNMP, and DMI. OpenView is one of the best SNMP applications for Unix available at this time, and its port to Windows will be a real boon for PC administrators. Whether your network is primarily based on DOS machines, Unix workstations, or even Macintoshes, SNMP 2 provides enough power and flexibility to live up to its name.
