Appendix A

Inter-Manager Communication

NEC ESMPRO software in a Manager can monitor approximately 100 units, although this number
varies according to what is monitored. You can register more than 100 units in the configuration
information on the screen. The number of units that can be managed depends on the performance of
managers and routers. Limitations occur when availability management is carried out on all
managed units within a short interval.
The NEC ESMPRO system exchanges packets with the SNMP Agent. To monitor many Agents
over a thin line, such as a private line, you should divide them into communities for best results.
Figure A-1 shows two different routing configurations.

Each Manager is recognized by a Manager name that consists of up to 63 characters including the
hyphen (-), underscore (_), and period (.). The Manager name can be changed in the My Manager
Dialog screen by selecting My Manager from the Customize menu in the Options menu.
