Inter-Manager Communication 91
You can group communities by network, level, or a combination of the two for inter-Manager
communication. Figures A-2 and A-3 show the two types of configurations. In Figure A-2, foo, bar,
and shina are Manager names. If you group communities by level, you may want to name the
communities using the Domain Name System (DNS).
Figure A-2 Network Manager Group
Figure A-3 Ladder Manager Group
In Figure A-3, the three communities, nvs, kawa.tk.nvs, and foo.tk.nvs, are directly connected to
each other. ks.nvs and tk.nvs are adjacent communities. A TCP/IP connection is always established
to adjacent communities. However, establishing a connection between two adjacent communities
requires making some settings in the Remote Manager dialog.
Indirect communication to a non-adjacent Manager can be made available with the Manager routing
function. For details about these procedures, see Setting Up Inter-Manager Communication, in
Chapter 3, Using the NEC ESMPRO Manager.
